How to group args with a parameter with getopt()

Question

I need to use two args with a parameter. But if I use the two args grouped then I want to enter the parameter only 1 time.

For example

./mycode -a 45

./mycode -b 45  

./mycode -ab 45

I suggest to simply *not do this*. This isn't how argument parsing works for basically any other argument parsing scheme. — Jonathon Reinhart, Oct 25 '18 at 00:28
This could make sense if it's something that looks like tar (i.e. `tar xvf file.tar`). Not sure getopt can do this though. — Jason Winnebeck, Oct 25 '18 at 01:27

As barmar commented,. getopt doesn't support this. It's one of those things "Wouldn't that be cool?" but do it 'by hand' in C is your only option. Not worth it IMHO. Here's a link to a longer S.O. thread describing your options for option processing:
