C++ is a high-performance, statically-typed, compiled language that extends C with object-oriented, generic, and functional programming paradigms. It powers systems software, game engines, high-frequency trading platforms, and performance-critical applications where direct hardware control and zero-cost abstractions are essential. The language evolves rapidly—C++20 introduced modules, ranges, concepts, and coroutines; C++23 stabilized them; C++26 is refining these features further. Understanding C++ means mastering both low-level memory control (pointers, manual allocation) and high-level abstractions (templates, lambdas, RAII). The key mental model: C++ gives you full control at every layer, but demands you understand the cost of every operation.
