Looping Question

akasuavity (4)
My question is: How would I just loop the output of (cardB == cardA)? Let's say for example, if the outcome was a tie, hence cardB == cardA, how would I add a loop so that it'll generate a new outcome?

All you have to do in this is to add a "do" loop around the code you wish to repeat. In my code I've also added "cin.ignore" so that the user has to press "enter" before another outcome is generated.

Hope this helps!
