C++ is an extension of the C programming language. This expanded version of C has features that allow for easier troubleshooting, more flexibility, and other benefits. C++ is popular for developers interested in programming graphical applications, which enable interaction with a user interface through icons instead of text.

With user-centered design increasingly becoming the goal of development teams, C++ is important to learn for people interested in programming intuitive computer systems and electronic devices.

C++ is also widely used for game and embedded-device programming, which is credited to its efficient memory usage.
