C++ Programming Introduction

C++ is a general-purpose, object-oriented programming language created by Bjarne Stroustrup starting in 1979 at Bell Labs, originally as an extension of C called “C with Classes.” It was renamed C++ in 1983. C++ keeps C’s performance and low-level memory control while adding object-oriented, generic, and functional programming features such as classes, templates, and the Standard Template Library (STL). It’s widely used for game engines, operating systems, browsers, and performance-critical applications.

Why Learn C++?

  • Builds directly on C, so the fundamentals carry over.
  • Used in game development, embedded systems, and high-performance software.
  • Strong support for OOP concepts: classes, inheritance, polymorphism.
  • Gives fine-grained control over memory and hardware resources.

Structure of a C++ Program

#include <iostream>   // Header for input/output
using namespace std;

int main() {
    cout << "Hello, World!" << endl;
    return 0;
}
ComponentPurpose
#include <iostream>Includes the input/output stream library
using namespace std;Avoids prefixing standard library names with std::
int main()Entry point of every C++ program
coutSends output to the console
return 0Indicates the program ended successfully
This is a starter page — more C++ topics (OOP, STL, templates) will be added here as modules, the same way the C Language section is structured.
