C is a procedural general purpose programming language developed in the early 1970s. The language focuses on execution speed, simplicity, and memory management. The main use of the C language is in low level programming, such as operating systems or drivers.
C++ is an object oriented general purpose programming language developed in the late 1970s. The language is similar to C, but with new functionalities.
