== Overview ==

'''C++''' is a general-purpose programming language created by [[Bjarne Stroustrup]] as an extension of the [[C (programming language)|C]] programming language. It was first developed at [[Bell Labs]] in the early 1980s under the name "C with Classes" and later renamed C++ in 1983. The language is designed to provide high performance, efficient use of hardware resources, and a rich set of abstractions including object-oriented, generic, and functional programming features.

C++ is widely used in systems programming, game development, real-time simulations, web browsers (e.g. [[Chromium (web browser)|Chromium]]), and large-scale server infrastructure. It is standardized by the [[ISO C++ Standard|International Organization for Standardization (ISO)]], with major versions including C++98, C++11, C++14, C++17, C++20, and C++23.

== History ==

Bjarne Stroustrup began work on "C with Classes" in 1979 at Bell Labs, aiming to combine the efficiency and portability of C with the organizing benefits of [[Simula]]’s class mechanism. The first commercial release appeared in 1985, and the language was renamed C++ to emphasize the incremental advancement over C (the "++" operator incrementing the value).

The first ISO standard, C++98, was published in 1998. It defined the core language and the [[C++ Standard Library]], including the Standard Template Library ([[STL]]). Subsequent revisions added library improvements and language features such as auto type deduction, range-based for loops, and variadic templates in C++11; generic lambdas and constexpr extensions in C++14; structured bindings, if constexpr, and fold expressions in C++17; and modules, coroutines, and concepts in C++20. C++23 introduced further library enhancements and refined language features.

== Features ==

C++ supports multiple programming paradigms. Key features include:

* '''Object-oriented programming''': classes, inheritance, polymorphism, and encapsulation.
* '''Generic programming''': templates enable type-parameterized functions and classes, allowing code reuse without sacrificing performance.
* '''Low-level memory manipulation''': pointers, references, and manual memory management, as well as the [[RAII]] (Resource Acquisition Is Initialization) idiom to manage resources safely.
* '''Standard Library''': containers (e.g. [[vector (C++ container)|vector]], [[map (C++ container)|map]]), algorithms, input/output streams, smart pointers, and multithreading support.
* '''Compile-time computation''': [[constexpr]] and [[consteval]] functions, templates, and the [[C++ Metaprogramming|template metaprogramming]] capabilities.
* '''Exception handling''': a mechanism to handle errors at runtime.
* '''Compatibility with C''': C++ maintains a high degree of source and linkage compatibility with C, allowing the use of C libraries directly.
