    looking for some functions in C

    hi

    I'm searching for a function defined in C that can recognize if a certain character is a digit or not... is there a "isDigit()" function in C?

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    Aye. In ctype.h, isdigit()
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein
