What are C files and how to open them
Are you having problems opening a C file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.
What is a C file?
C files have multiple uses, and C Source Code is one of them. Read more about the other uses further down the page.
C Source Code File
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 initially 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.
