While loop is not working

jekaterina (40)
I am writing a program for mcdonald ordering system, now I extracted one part of my program. I don't know why the while loop is not working, it just runs once.

Does it even compile?

EDIT:...
but anyway, the problem is likely with the line (54) else solved=0;break;}. I suspect you want something like

1
2
3
4
5
6
7
 
//...
   else
   {
        solved = 0;
        break;
    }
}

as it is it will break on the first run.

Getting it to run even once would be a bonus.

cause I only extracted one part of the whole coding so thats why i forgot to include those initializations

And the problem really exists in else solved=0;break;}. Thanks!
