About C++ Programming

C++ is a powerful, general-purpose programming language that extends C with object-oriented features. It's widely used in system programming, game development, embedded systems, and high-performance applications.

Modern C++ (C++11 and later) introduces many features that make the language more expressive and safer, including smart pointers, lambda functions, and automatic type deduction.
