FAQ: C

$ gcc -o firstprogram firstprogram.c

If your file is named firstprogram.c then type ‘-o firstprogram’ as the parameter to gcc. This is basically your suggested name for the executable file that gcc would create. In case you typed something like the following

$ gcc firstprogram.c

You would be having a a.out in the same directory as the source C file. This is the default name of the executable that gcc creates. This would create problems when you compile many programs in one directory. So you override this with the -o option followed by the name of the executable

$ gcc -o hello secondprogram.c

Would create an executable by the name hello for your source code named secondprogram.c

Running the executable that you created is as simple as typing the following at the prompt.

$ ./firstprogram
OR
$ ./hello
