The C compiler does not know what to call your final executable, so it has defaulted the name to a.out.

It is unusual for the compiler to place the output in the /usr/bin directory, usually it is placed into your current directory.

Nearly all compiliers, including those on Unix and Linux will accept a number of command line switches and parameters. By using command line parameters you can change the behaviour of the compiler significantly. See for yourself by doing:

man cc

or

man gcc

This will give you a very lengthy description of what to expect from your compiler. Also read the man page on your linker.

man ld

Somewhere in that lot will be a way to change the output file name. If necessary you can give it an explicit path name.


Finally, if you did not realise it already, the a.out file is (or should be) a fully runnable executable. You can always rename it using the move or copy command!

Regards

MBB.
