What is C++?

C++ is a powerful, high-performance programming language developed by Bjarne Stroustrup in 1979 at Bell Labs. It was originally called “C with Classes” before being renamed to C++ in 1983.

C++ is an extension of the C programming language. It adds object-oriented programming features while keeping the speed and efficiency of C.

Why Learn C++?

  • It is one of the most widely used programming languages.
  • C++ is very fast and efficient.
  • It is used to develop operating systems, games, and large applications.
  • It supports both procedural and object-oriented programming.
  • Learning C++ helps in understanding many other programming languages.

Key Features of C++

  • Object-Oriented Programming – Supports classes and objects.
  • High Performance – Compiles directly to machine code.
  • Memory Control – Provides direct access to memory.
  • Portability – Programs can run on different platforms.
  • Rich Standard Library – Includes STL (Standard Template Library).

Basic Example

The following example shows a simple C++ program that prints a message.

#include <iostream>
using namespace std;

int main() {

    cout << "Hello, World!";

    return 0;
}

Applications of C++

C++ is used in many real-world applications such as:

  • Game development
  • Operating systems
  • Web browsers
  • Database systems
  • Embedded systems
  • Financial and banking software

Advantages of C++

  • Very fast execution speed
  • Powerful object-oriented features
