2 users enter 2 different numbers, and I want to continue to ask to User 1 and User 2 to try to guess the opponent numbers. When one of the Users guess the other User numbers, the loop ends and the "Game is Over"

I cannot use pointers.

I don't really know how to do it, i'm still kinda new in c programming.

I was trying to put 2 Do While loops inside another Do While, but it's not working.

Any help?
