C++ programming language is a general-purpose, statically typed, free and open-source software language. It was developed by Bjarne Stroustrup at Bell Labs between 1979 and 1985. It supports object-oriented, imperative, and generic programming paradigms. C++ is a very powerful programming language that is used to develop many types of applications. It is one of the most popular languages in the world. These libraries make it easy for developers to build C++ applications that are modular, scalable and high performing. C++ is used for operating system development, desktop applications, mobile apps, and games. It provides a lot of flexibility, and it is used in many different areas. Some of the most popular C++ Application Open Source libraries among developers are: dlib - A toolkit for making real world machine learning and data analysis applications in C; drogon - Drogon: A C++14/17/20 based HTTP web application framework running on Linux/macOS/Unix/Windows; oatpp - Light and powerful C web framework for highly scalable and resourceefficient web application.
