Also known as: C++, cpp, C plus plus

C++ is a statically typed, compiled language that extends C with objects, templates, generics, RAII and a large standard library.1 It can match C’s performance while offering far higher-level abstractions.

C++ layers objects, generics and RAII over C's fast native model — power at the price of complexity.

Overview

C++ compiles ahead of time to native code like C, but adds object-oriented features, compile-time generics through templates, and the Standard Template Library.2 Its signature idiom is RAII — tying resource lifetimes to object scope — which gives a disciplined approach to memory management and, with smart pointers, much of the safety of automatic management without a garbage collector.

Strengths and trade-offs

The strength is reach: C++ delivers C-level performance while letting you build large, abstracted systems, which is why it dominates game engines, browsers, high-frequency trading and serious DSP. The drawback is complexity — the language is vast, with decades of accumulated features and sharp edges, and it inherits C’s memory-safety risks unless you are disciplined. It is genuinely hard to master. For new systems work where safety is paramount, Rust is increasingly chosen as an alternative that keeps the speed without the same footguns.

Where it’s used

C++ is the workhorse of performance-critical software with rich logic: game engines, web browsers, trading systems, scientific and signal-processing code, and other domains where both raw speed and high-level structure are required at once.
