What are C files and how to open them

Are you having problems opening a C file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your C 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.
