    What's your second name? I might know you... a Stu from the UK I've been looking for recently.

    You have to delare a variable before you can use it.

    In your example, if c is a number type, do this

    Code:
    int c;
    if c is a character type, do this

    Code:
    char c;
    Remeber to delcare all variables you will be using in the main function to make them
    local - try not to use global ( declared outside main ) as they can cause confusion.
