Learn CPP with Real Code Examples

C++ is a compiled, high-performance language supporting procedural, object-oriented, and generic programming.

It offers fine control over memory with RAII and manual management.

Widely used for performance-critical systems, games, engines, and large-scale applications.

Classes, objects, inheritance, polymorphism

Templates and metaprogramming

Smart pointers for memory safety
