What is C++ 11?

C++11 is a version of the ISO/IEC 14882 standard for the C++ programming language. It replaced the prior version of the standard, called C++03, and was later superseded by C++14. C++11 introduced significant improvements to the core language, providing features like lambda expressions, range-based for loops, auto keyword for type inference, move semantics, variadic templates, and concurrency support via threads and atomic operations. It is widely used for developing high-performance applications, system software, game development, and other areas where performance and control over hardware resources are critical.
