C++98 (1998): - Initial release of the C++ programming language standard. - Introduced core features such as classes, templates, and the Standard Template Library (STL).
C++03 (2003): - A bug-fix release to address issues identified in C++98. - No new features were introduced; focused on improving the existing standard.

- Significant update introducing features like auto keyword, lambda expressions, range-based for loops, and smart pointers.
- Introduces the concept of move semantics to optimize resource management.
- Enhanced support for multithreading with the introduction of the <thread>

C++14 (2014):
- A minor update building on C++11, aimed at improving language features without introducing major changes.
- Introduces features like generic lambdas, relaxed constexpr
restrictions, and binary literals.
C++17 (2017):
- Adds features such as std::optional
, std::variant
, std::any
, and parallel algorithms.
- Enhancements to existing features like constexpr
