Hi.
I,ve got some very helpfull advice from various experts on here and have nearly finished my program but am having a problem with a do while loop. When i try to put a do while ( the input isn't numbers one to ten) loop on a certain part of my program it works fine when a number that isn't one to ten is put in but if you put in a letter (which should make that part repeat again) it just dies and the screen starts flickering. I have tried a few things but with no joy. My only other idea was to use letters a to j instead. Hopefully this would work because later on in the program i have another two do while loops working on the exact same principle but with letters and they work fine when either the wrong letter is input or a number is input.
The only problem i have is that i use a switch statment to return a statement and if i use letters for the choice at the beginning i will need to make the switch statement work with case a: case b: etc. and not case1: case 2: etc.
Is there any way you can set up a switch statement to work with lettters for each case? It is slightly annoying that i cant get the do while loop working at the beginning but it just doesn't like it when you put a letter in and not a number.
Any help would be great. Thankyou.

Jump to Postcase statements must be constants. You can not use variables there
switch( some_variable ) { case 'a': // blabla break; case 'b': // blabla break; case 'c': case 'd': case 'e': // this for all three characters break; <etc. etc for each letter you want to support> …
