Hello ! I'm interested in working on this issue. Could you please elaborate the issue though ? I am fairly new to this.

Hi @linton-dawson

If you build the program, and give it the --help option, it will spit out the message that it's an invalid option. When --help is given, it should show the usage.

It should do the same thing as when -h is given.

One way to do it would be to use getopt.h

This is an example of a program getting command line options when the getopt.h header is included

That single line would mean that --help would be accepted, or -h
