Error How to decrease a string number by one in C?

If i have a macro called NUM which is "8" (string) for example
How do I make it into say "7", well i just want to lower it by one, also there will never be the case where its "0" and i have to decrease it.
there is no guarantee how many digits NUM could have, but will always be an integer.
How do I do the conversion?
