C++ Programming Tutorial

Introduction to C++

C++ is a fast, compiled programming language used to build operating systems, embedded software, high-performance backends, game engines, and desktop/mobile apps. It blends procedural and object-oriented paradigms, with fine-grained control over memory and performance.

What You Can Build

• High-performance APIs, servers, and microservices
• Game engines, physics simulations, and rendering systems
• Cross-platform desktop apps (Qt, wxWidgets)
• Embedded systems and device firmware

Key Features

• Object-Oriented Programming (classes, inheritance, polymorphism)
• Generic Programming with Templates
• Rich standard library (STL) with containers and algorithms
• Low-level memory control with pointers and references

#include \n\nint main() {\n    std::cout << "Hello, C++!" << std::endl;\n    return 0;\n}

Tips

• Use modern standards (C++17/C++20) for better safety and features.
• Prefer standard containers (`std::vector`, `std::string`) over raw arrays.
• Avoid manual memory management where possible; consider RAII and smart pointers.
