Printing leading 0's in C?

Question

I\'m trying to find a good way to print leading 0\'s, such as 01001 for a zipcode. While the number would be stored as 1001, what is a good way to do it?

I thought

Answer 1

You will save yourself a heap of trouble (long term) if you store a zip code as a character string, which it is, rather than a number, which it is not.
