What is a C File?
A file with a .C extension is a code file that can be written in the C or the C++ programming language. It may contain an entire source code, or only a part of it, in which case multiple .C files work together to perform a task. Developers usually open and edit such files in a Software Development Environment (SDE) program or compilers, but can also be edited in any text editor, since the files are in plain text format.
Note that certain Unix operating systems use the “.c” (lowercase) extension for files having code in the C programming language, and “.C” (uppercase) for the C++ programming language.
