Introduction to C++ [ English ]

< PrevNext >

C++ is a general-purpose, high-performance programming language widely used for building system software, application software, games, and performance-critical programs. It was developed in the early 1980s by Bjarne Stroustrup as an extension of the C language, with the goal of adding object-oriented programming features while keeping C’s speed and low-level control.

C++ combines low-level efficiency with high-level abstractions, making it powerful, flexible, and suitable for both hardware-close programming and large-scale software development.

Key Features of C++

  • Object-Oriented Programming (OOP)Supports classes and objects, along with core OOP concepts like encapsulation, inheritance, polymorphism, and abstraction.

  • Fast and EfficientCompiled language with direct memory access using pointers, ideal for performance-critical applications.

  • Multi-Paradigm LanguageSupports procedural, object-oriented, and generic programming (using templates).

  • Rich Standard Library (STL)Provides ready-made components such as vectors, lists, maps, algorithms, and iterators.

  • PortableC++ programs can be compiled and run on different platforms with little or no modification.

  • Compatibility with CMost C programs can be compiled using a C++ compiler.

Where C++ Is Used

  • Operating systems and system software
  • Game development and graphics engines
  • Embedded systems and real-time applications
  • Compilers and interpreters
  • High-performance applications (banking, simulations, AI engines)

Why Learn C++?

  • Gives strong fundamentals of programming and memory management
  • Helps understand how software interacts with hardware
  • Forms the foundation for many modern languages
  • Essential for careers in systems programming, game development, and competitive programming
