Introduction
C++ a general-purpose programming language. It has
imperative, object-orientedand generic programming
features, while also providing the facilities for low-
level memory manipulation.
It is designed with a bias toward system programming
(e.g., for use in embedded systems or operating
system kernels), with performance, efficiency and
flexibility of use as its design requirements

History
Bjarne Stroustrup, a Danish computer scientist, began his work on C++'s
predecessor "C with Classes" in 1979.
The motivation for creating a new language originated from Stroustrup's
experience in programming for his Ph.D. thesis. Stroustrup found
that Simula had features that were very helpful for large software
development, but the language was too slow for practical use, while BCPL was
fast but too low-level to be suitable for large software development.
When Stroustrup started working in AT&T Bell Labs, he had the problem of
analyzing the UNIX kernel with respect to distributed computing.
Remembering his Ph.D. experience, Stroustrup set out to enhance
the Clanguage with Simula-like features.
C was chosen because it was general-purpose, fast, portable and widely used.
As well as C and Simula's influences, other languages also influenced C++,
including, ALGOL 68, Ada, CLU and ML.

Etymology
According to Stroustrup “The name signifies the evolutionary nature
of the changes from C". This name is credited to Rick Mascitti (mid-
1983) and was first used in December 1983.
When Mascitti was questioned informally in 1992 about the naming,
he indicated that it was given in a tongue-in-cheek spirit. The name
stems from C's "++" operator (which increments the value of
a variable) and a common naming convention of using "+" to indicate
an enhanced computer program.
A joke goes that the name itself has a bug: due to the use of post-
increment, which increments the value of the variable but evaluates
to the un incremented value, so C++ is no better than C, and the pre-
increment ++C form should have been used instead, so that C++ is
better than C.
During C++'s development period, the language had been referred to
as "new C", then "C with Classes", before acquiring its final name.
