C Related File Extensions

Overview
The following table lists the standard file extensions used for C-related files. The extension normally indicates how far the file is through the compilation process. Note that many integrated development environments (IDEs), and command-line compilers hide most of the individual compiler steps from the user.
| File Extension | Description |
|---|---|
file-name.c | C source code which must be preprocessed. |
file-name.i | C source code which should not be preprocessed. |
file-name.h | C header file (not to be compiled or linked). |
file-name.s | Assembler code. |
file-name.S | Assembler code which must be preprocessed. |
file-name.o | Object file by default, the object file name for a source file is made by replacing the extension .c, .i, .s etc with .o. This can be changed with a command line parameter. |
file-name | If the file has no extension, this is usually the final executable (NIX systems). |
file-name.exe, .dll, .com | The final executable on a Windows system. |
