Helpful Batch Files

The following one-line batch files are convenient for compiling small C programs in DOS. (The gcc compiler is assumed, though the files can be modified in an obvious way for any compiler.) Comments within the files explain their functions.

ccc.bat
cccW.bat

Suggestion: Turn DOSKEY on so the command “ccc” or “cccW” can be run repeatedly with only a few keystrokes.
