hi all I have a question, how do you break out of a loop. i am building game and it is doing what it supposed to do but the problems is when the user enter a wrong answer it supposed to go back to the same question and repeat the question. the thing it is repeating the question but at the wrong level and wrong question and also it is in a loop. here is my codes.
?

I believe that the loop you are getting caught inside of is the 'while' loop declared on line 41. Currently, its condition to continue looping is that the value of 'count' be less than four (4). Since the value of 'count' is not altered anywhere inside the 'while' block (lines 42 through 70), once inside, you will never get smoothly out of it. You either need to increase the value of 'count' somewhere inside the loop or change the condition used to keep the loop going to something that will eventually become 'false' within the loop. A good candidate to keep the loop going might be that the value of 'ans' is not 'a' (or, as long as the question is not answered correctly, keep the loop going). Or, maybe a combination of conditions can be used -- like if not answered correctly within four tries. Something you ought to consider is starting the 'while' loop before any attempt to answer a question (that should help to simplify the code a bit). Another thing that does not help is setting 'i' back to one (1) on a wrong answer. So, for example, with that, if the fourth question is answered wrong, three more question will be forthcoming.

I would set 'ans' to some unused character (maybe a blank -- ' '); then, use the condition:
?
1
while (ans != 'a')
to control the looping.
