How do I repeat a question to the user? I don't want to ask an identical question I want to repeat the same one.
I have written my code so it will ask a question, wait for a responce, determine if that response is correct or incorrect. If the response is correct the code will move on. If the response is incorrect the code should repeat the question until the user gets it right.
Up until this point I thought I had it figured out but I will eventurally be asking randomly generated questions and if the user gets one of those wrong I will need to repeat that particular question until they get if correct.
line 81 is the problem area.
Bonus: Do you think that lines 97, 104, 111, and 118 are necessary?
