This document discusses different types of constructors in C++, including default, parameterized, and copy constructors. It provides examples of how to define each type of constructor and demonstrates their usage when creating objects. Destructors are also covered, along with an overview of their purpose to destroy objects and free allocated memory. Constructor overloading and the use of the "this" keyword in C++ are further explained with additional examples.
Constructors are special class functions which performs initialization of every object. The Compiler calls the Constructor whenever an object is created. Destructor on the other hand is used to destroy the class object.
This document discusses exception handling in C++. It defines an exception as an event that occurs during program execution that disrupts normal flow, like divide by zero errors. Exception handling allows the program to maintain normal flow even after errors by catching and handling exceptions. It describes the key parts of exception handling as finding problems, throwing exceptions, catching exceptions, and handling exceptions. The document provides examples of using try, catch, and throw blocks to handle exceptions in C++ code.
Classes allow users to bundle data and functions together. A class defines data members and member functions. Data members store data within each object, while member functions implement behaviors. Classes support access specifiers like public and private to control access to members. Objects are instances of classes that allocate memory for data members. Member functions can access object data members and are called on objects using dot notation. Friend functions allow non-member functions to access private members of classes.
This document discusses the five main types of tokens in C++ - keywords, variables, constants, strings, and operators. It provides definitions and examples of each token type. Keywords are reserved words that cannot be used as variable names, while variables store values that can change. Constants represent fixed values, strings group characters within double quotes, and operators perform actions on operands like arithmetic, comparison, and assignment.
This document discusses different uses of the "this" pointer in C++ classes. This pointer points to the object whose member function is being called. It can be used to return the object from a member function, access the memory address of the object, and access data members within member functions. Sample programs are provided to demonstrate returning an object using this, displaying the memory address of an object using this, and accessing a data member within a member function using this->.
C++ functions require prototypes that specify the return type and parameters. Function overloading allows multiple functions to have the same name but different signatures. Default arguments allow functions to be called without providing trailing arguments. Inline functions expand the function body at the call site for small functions to reduce overhead compared to regular function calls.

The document discusses access specifiers in C++ classes. There are three access specifiers: public, private, and protected. Private restricts access to class members to only within the class, public allows access from anywhere, and protected is used for inheritance but not discussed here. By default, members are private. Public members can be accessed from outside the class, while private members can only be accessed within class functions. Access specifiers control the scope and accessibility of class members.
Constructor functions are special member functions used to initialize objects. They are called whenever an object is created. Key points:
- Constructors have the same name as the class and do not return a value.
- The default constructor takes no arguments and initializes objects if no other constructor is defined.
- Parameterized constructors allow passing arguments to initialize object attributes.
- Constructors can be overloaded to support different initialization scenarios.
- The destructor function is called when an object is destroyed to perform cleanup tasks. It is prefixed with a tilde and has no parameters or return type.
Pointers,virtual functions and polymorphism cpprajshreemuthiah
This document discusses key concepts in object-oriented programming in C++ including polymorphism, pointers, pointers to objects and derived classes, virtual functions, and pure virtual functions. Polymorphism allows one name to have multiple forms through function and operator overloading as well as virtual functions. Pointers store the memory address of a variable rather than the data. Pointers can be used with objects, arrays, strings, and functions. Virtual functions allow calling a derived class version of a function through a base class pointer. Pure virtual functions define an abstract base class that cannot be instantiated.
The document discusses various data types in C++ including built-in, user-defined, and derived types. Structures and unions allow grouping of dissimilar element types. Classes define custom data types that can then be used to create objects. Enumerated types attach numeric values to named constants. Arrays define a collection of elements of the same type in sequence. Functions contain blocks of code to perform tasks. Pointers store memory addresses.
This document discusses the diamond problem that can occur with multiple inheritance in C++. Specifically, it shows an example where a class "four" inherits from classes "two" and "three", which both inherit from class "one". This results in two copies of the base class "one" being present in objects of class "four", leading to ambiguity when trying to access attributes from the base class. The document presents two ways to resolve this issue: 1) manual selection using scope resolution to specify which attribute to access, and 2) making the inheritance of the base class "one" virtual in classes "two" and "three", which ensures only one copy of the base class exists in class "four" objects. The virtual
A destructor is a special member function that is called automatically when an object is destroyed or goes out of scope. It performs cleanup actions like freeing memory allocated to the object. Destructors are defined with a tilde symbol preceding the class name and they take no arguments and return no value. They are mainly used to delete dynamically allocated memory for an object and its members before the object is destroyed.
Exceptions are runtime errors that a program may encounter. There are two types: synchronous from faults in input data, and asynchronous from external events. Exception handling uses try, throw, and catch keywords. Code that may cause exceptions is placed in a try block. When an exception occurs it is thrown, and the catch block handles it to prevent program termination. Multiple catch blocks can handle different exception types, and a catch-all block uses ellipses to catch any exception.
Abstraction in c++ and Real Life Example of Abstraction in C++Hitesh Kumar
1. Real life examples of abstraction in C++ include operating a mobile phone without understanding its internal details and driving a car without knowing its inner mechanisms like how the accelerator increases speed.
2. Abstraction in C++ refers to hiding background implementation details and exposing only essential features to users. For example, a user presses the accelerator of a car to increase speed without knowing how this actually works internally.
3. Advantages of abstraction in C++ include increased code reusability and readability by hiding complex workings, enhanced security by restricting access to class members and functions, and allowing users to write code at a high level without dealing with low-level implementation.

This document discusses templates in C++. Templates allow functions and classes to work with multiple data types without writing separate code for each type. There are two types of templates: class templates, which define a family of classes that operate on different data types, and function templates, which define a family of functions that can accept different data types as arguments. Examples of each template type are provided to demonstrate how they can be used to create reusable and flexible code.
This document discusses classes and objects in C++. It defines a class as a user-defined data type that implements an abstract object by combining data members and member functions. Data members are called data fields and member functions are called methods. An abstract data type separates logical properties from implementation details and supports data abstraction, encapsulation, and hiding. Common examples of abstract data types include Boolean, integer, array, stack, queue, and tree structures. The document goes on to describe class definitions, access specifiers, static members, and how to define and access class members and methods.
The document contains information about Tarandeep Kaur, including her name, section, and roll number. It then lists and describes various topics related to functions in C++, including definition of functions, function calling, function prototypes, void functions, local vs global variables, function overloading, and recursion. Examples are provided to illustrate function calling, passing arguments, return values, and differences between call by value and call by reference.
Functions allow programmers to break programs into smaller, reusable parts. There are two types of functions in C: library functions and user-defined functions. User-defined functions make programs easier to understand, debug, test and maintain. Functions are declared with a return type and can accept arguments. Functions can call other functions, allowing for modular and structured program design.
An operator is a symbol designed to operate on data.
They can be a single symbol, di-graphs, tri-graphs or keywords.
Operators can be classified in different ways.

This document discusses dynamic memory allocation in C. It explains that dynamic allocation allows memory to be allocated at runtime, unlike static allocation which requires defining memory sizes at compile time. The key functions covered are malloc() for allocating memory blocks, calloc() for arrays and structures, realloc() for resizing allocated blocks, and free() for releasing used memory to avoid memory leaks. Examples are provided to demonstrate how each function is used.
Static Data Members and Member FunctionsMOHIT AGARWAL
Static data members and static member functions in C++ classes are shared by all objects of that class. Static data members are initialized to zero when the first object is created and shared across all instances, while static member functions can only access other static members and are called using the class name and scope resolution operator. The example program demonstrates a class with a static data member "count" that is incremented and accessed by multiple objects to assign increasing code values, and a static member function "showcount" that prints the shared count value.
The document discusses functions in C programming. It defines a function as a self-contained block of code that performs a specific task. Functions make code more modular and reusable. There are two types of functions: standard/library functions and user-defined functions. Functions can take input parameters and return values. Functions are an essential part of program structure in C as they help organize code and logic.
This document discusses C++ friend functions and classes. It explains that friend functions have access to private and protected members of a class, but are not members themselves. Friend functions are declared using the friend keyword within the class definition. Friend classes also have access to private members, and are declared using the friend class syntax. Examples are provided to illustrate friend functions for operator overloading and accessing members of multiple classes.
C Programming/Strings. A string in C is merely an array of characters. The length of a string is determined by a terminating null character: '-' . So, a string with the contents, say, "abc" has four characters: 'a' , 'b' , 'c' , and the terminating null character.
CONSTRUCTORS, DESTRUCTORS AND OPERATOR OVERLOADING.pptxDeepasCSE
Certainly, here's a brief explanation of constructors, destructors, and operator overloading without using code:
Constructors: Constructors are special methods used to initialize objects of a class. They set the initial state of an object when it is created.
Destructors: Destructors are special methods used to clean up resources and perform necessary cleanup when an object is no longer needed or goes out of scope. They ensure proper resource management.
Operator Overloading: Operator overloading is a feature that allows you to define custom behaviors for operators such as +, -, *, /, etc., when they are applied to objects of your class. It enables you to work with objects in a way that is meaningful for your specific class.
Constructors can be of different types:
Default Constructors: Initialize objects with default values.
Parameterized Constructors: Accept arguments to initialize objects with specific values.
Copy Constructors: Create a new object as a copy of an existing object.
Constructor Overloading: A class can have multiple constructors with different parameter lists, providing flexibility in object initialization.
Destructors are executed automatically when an object is destroyed. They are essential for releasing resources like memory, file handles, or network connections, ensuring proper cleanup and preventing resource leaks.
Operator overloading enables you to define how operators work with objects of your class. For instance, you can specify what the + operator does when applied to two objects of your class, allowing for custom operations that make sense in the context of your class's functionality.
In summary, constructors initialize objects, destructors handle cleanup, and operator overloading allows custom operations with operators when working with objects. These features are crucial for building custom classes in object-oriented programming.
1. Constructors are special member functions used to initialize objects. They are called whenever an object is created and have the same name as the class.
2. Constructors can be default, parameterized, overloaded, or have default arguments. The default constructor takes no arguments.
3. A destructor is a special function that is called when an object is destroyed. It performs cleanup tasks like closing files. It has the same name as the class but preceded by a tilde (~).
The document discusses access specifiers in C++ classes. There are three access specifiers: public, private, and protected. Private restricts access to class members to only within the class, public allows access from anywhere, and protected is used for inheritance but not discussed here. By default, members are private. Public members can be accessed from outside the class, while private members can only be accessed within class functions. Access specifiers control the scope and accessibility of class members.

The Dijkstra algorithm is used to find the shortest path between a source node and all other nodes in a graph. It works by assigning initial distances from the source node of infinity for all other nodes. It then repeatedly selects the unvisited node with the lowest distance, calculates the distance through it to each neighbor, and updates distances if shorter than the previous value. It returns the shortest distances and predecessors for each node. The algorithm works for both directed and undirected graphs that are connected.
The document discusses the Entity Relationship (ER) model and ER diagrams. The ER model is a conceptual data modeling technique that is used to produce a database design. It displays entities, attributes, and relationships between entities. ER diagrams help visualize these components and the logical structure of databases. Some key benefits of ER diagrams include defining database terms, providing a preview of how tables connect, and allowing communication of the database structure. Common components of ER diagrams are entities, attributes, and relationships.
Dijkstra's algorithm is used to find the shortest path between a source node and all other nodes in a connected graph. It works by computing the shortest path from one particular source node to all other remaining nodes. The algorithm provides the cost or value of the shortest paths between the source node and all other nodes in the graph, whether directed or undirected.
DFS uses a stack to perform a depth first traversal of a graph, which produces a spanning tree without loops as the final result. It selects a starting vertex, visits it and its non-visited neighbors, pushing them on the stack until there are no more to visit, then backtracks and pops vertices off the stack until it is empty, producing the final spanning tree.
The document discusses different types of intelligent agents in artificial intelligence. It defines an agent as anything that can perceive its environment through sensors and act upon the environment through effectors. It then describes different types of agent programs:
1) Simple reflex agents that take actions based solely on current percepts.
2) Model-based reflex agents that maintain an internal state based on past percepts allowing them to operate in partially observable environments.
3) Goal-based agents that choose actions to achieve goals by considering long sequences of possible actions through planning.
4) Utility-based agents that act not just based on goals but also to maximize utility or success at achieving goals.
5) Learning agents that can

It provides pseudocode for DFS and BFS algorithms and examples of their use. It also notes that graph theory is used for shortest path algorithms like Dijkstra's, Prim's and Kruskal's.
Queue is a linear data structure where elements are inserted at the rear end and removed from the front end, making it a First In First Out (FIFO) structure. Elements are added to the back of the queue and the earliest elements exit from the front, similarly to waiting in line. Queues are useful for serving single shared resources like printers, scheduling CPU tasks, handling calls in call centers, and processing interrupts in real-time systems in the order they arrive.
A tree is a nonlinear data structure that consists of a root node and zero or more subtrees. The root node can have any number of child nodes, but each child can only have one parent. Nodes maintain a parent-child relationship, with one node designated as the root and the remaining nodes forming non-empty subtrees below the root. Trees allow for hierarchical categorization of data.
The document discusses applying a stack to evaluate arithmetic expressions. It provides examples of converting infix expressions to prefix expressions by reversing the order of operations and operands and pushing them onto a stack. It also gives examples of stack operations like push, pop, and arithmetic operations between popped elements to evaluate postfix expressions.
This document discusses stacks as a linear data structure that follows the LIFO (Last-In First-Out) principle. Key points include:
- Stacks allow insertion and deletion from one end only (the top) through PUSH and POP operations.
- Common applications of stacks include reversing strings, checking validity of expressions with nested parentheses, and converting infix notation to postfix notation for arithmetic expressions.
- The document provides examples and algorithms for common stack operations like insertion, deletion, and display.
Heap sort is a sorting algorithm that uses a heap data structure. It has two main steps: 1) transforming the array into a max or min heap, and 2) performing the actual sort by extracting the largest/smallest element and transforming the remaining heap. Heap sort runs in O(n log n) time and uses O(1) constant memory, making it an efficient in-place sorting algorithm.
Quick sort is a divide and conquer sorting algorithm that works by partitioning an array around a pivot value. It then recursively sorts the sub-arrays on each side of the pivot. The key steps are: 1) Choose a pivot element to divide the array; 2) Partition the array by swapping elements such that all elements less than the pivot come before it and all greater elements come after; 3) Recursively apply the same process to the sub-arrays on each side of the pivot until the entire array is sorted.
This document discusses different types of linked lists including singly linked lists, doubly linked lists, and circular linked lists. It describes the basic structure of nodes in each type of linked list and common operations like insertion, deletion, traversal, and searching. Circular linked lists are defined as lists where the last node points back to the first node, forming a continuous loop without a null terminator.

This document compares key differences between C and C++ programming languages. It lists 12 points of comparison between the two languages. Some key differences mentioned are:
1) C follows procedural programming while C++ supports both procedural and object-oriented programming.
2) C++ allows for better data encapsulation and security through access modifiers for class members.
3) C follows a top-down approach while C++ follows a bottom-up approach.
4) C++ supports features like function overloading, inheritance, exception handling, and namespaces that are not present in C.
The document discusses the JSTL (JSP Standard Tag Library) which represents a set of tags to simplify JSP development. It provides advantages like fast development and code reusability. The core JSTL tags provide variable support and flow control. Common tags are outlined along with their purposes. Function, formatting, XML and SQL tags are also introduced and example uses are shown for SQL tags like <sql:setDataSource> and <sql:query> to connect to a database and execute queries.
Hill climbing algorithm in artificial intelligencesandeep54552
The hill climbing algorithm is a local search technique used to find the optimal solution to a problem. It works by starting with an initial solution and iteratively moving to a neighboring solution that has improved value until no better solutions can be found. Simple hill climbing only considers one neighbor at a time, while steepest ascent examines all neighbors and chooses the one closest to the optimal solution. The algorithm can get stuck at local optima rather than finding the global optimum. Techniques like simulated annealing incorporate randomness to help escape local optima.
Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

20. When Copy Constructor is called
• When we initialize the object with another
existing object of the same class type. For
example, Student s1 = s2, where Student is
the class.
• When the object of the same class type is
passed by value as an argument.
• When the function returns the object of the
same class type by value.
21. #include<iostream.h> Copy Constructor Example
#include<conio.h>
class A
{
public: int x;
A(int a) // parameterized constructor.
{
x=a;
}
A(A &i) // copy constructor
{
x = i.x;
} };
int main()
{
A a1(20); // Calling the parameterized constructor.
A a2(a1); // Calling the copy constructor.
cout<<a2.x;
getch(); }

27. Rules for Destructors
• Destructor is a type of special member function of a
class.
• It is used to destroy the memory allocated by the
constructor.
• It has the same name as the class prefixed with a tilde
(~) sign.
• Destructor does not take any arguments and cannot
return or accept any value.
• It is called automatically by the compiler when the
object goes out of scope.
• Compiler calls the destructor implicitly when the
program execution is exited.

33. Example - 1 Constructor Overloading
class Student
{
public:
int rollno;
string name;
Student(int x) // first constructor
{
rollno = x;
name = "None";
}
34. Student(int x, string str) // second constructor
{
rollno = x;
name = str;
}};
int main()
{
Student A(10);
Student B(11, "John");
getch();
}
35. Example - 2 Constructor Overloading
#include <iostream.h>
#include <conio.h>
class ABC
{
private:
int x,y;
public:
ABC () //constructor 1 with no arguments
{
x = y = 0;
}
ABC(int a) //constructor 2 with one argument
{
x = y = a;
}
36. ABC(int a, int b) //constructor 3 with two argument
{
x = a;
y = b;
}
void display()
{
cout << "x = " << x << " and " << "y = " << y << endl;
} };
int main()
{
ABC cc1; //constructor 1
ABC cc2(10); //constructor 2
ABC cc3(10,20); //constructor 3
cc1.display();
cc2.display();
cc3.display();
getch(); }
37. this Keyword
this is a keyword that refers to the current
instance of the class. There can be 3 main
usage of this keyword in C++.
• It can be used to pass current object as a
parameter to another method.
• It can be used to refer current class
instance variable.
• It can be used to declare indexers.
