    WHILE LOOP problem

    uggg....oh man i will probably figure it out before anybody respods but just incase i don't here's my problem. it's soo anoying

    i'm asking the user to enter n (notice small) if they don't want the program to continue, but when they press 'N' (notice capital) my loop just continues. so i tried fixing it with this statement:

    while(ch!='n' || ch!='N')

    but now the problem is that the loop continues if the user enters n or N. not what i want. i want the program to exit when the user enters n or N. any thoughts on this would be greatly appreciated. thx

    ... or use toupper() and then only test against capitals.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    || is "or"
    && is "and"

    Read the logic of the test, and you should understand. You want both tests to be true to keep the loop going.
    When all else fails, read the instructions.
