Structure of a C++ Program
C++ is a general-purpose and object-oriented programming language developed by Bjarne
Stroustrup at AT&T Bell Labs. It is an extension of the C language. It has features of low-level
languages as well as high-level languages. We can develop wide variety of applications using
C++. Initially, C++ was used to create system software and embedded software. Later it was also
used to develop desktop applications, video games, servers and many more.
C++ was initially standardised in 1998 by International Organization for
Standardization (ISO). However, the development of C++ was started in
1979 with the name “C with Classes”. Later the name was changed to C++.
The (++) is an increment operator in C language. The latest standardized
version of C++ is released in December 2020 as C++20.
In this chapter, you will learn the basic concepts of C++.

According to TIOBE index, C++ is the fourth popularly used programming language after C,
Java and Python.
FEATURES OF C++
Some of the important features of C++ language are:
Object-Oriented Programming: C++ gives preference to the objects rather than the
procedure or the method used in the program. These objects help you to implement real-
time problems in your program.
Platform Independent: C++ supports multiple platforms which means the program
developed on a Windows operating system works in a similar manner on other operating
systems like Linux.
