Files that contain the .c file extension normally contain source code that has been written for C or C++ programs. The C file may contain the source code for an entire program or a single source file that is to be referenced within a specific programming project.
The C programming language was developed as a general-purpose computer language by Dennis Ritchie. It was originally intended to be used for Unix operating systems. In 1983 the C++ programming language was developed by Bjarne Stroustrup as an enhancement to the original C language. Both the C and C+++ languages are two of the most widely-used programming languages in use today.
