How to repeat a char using printf?

I'd like to do something like printf("?", count, char) to repeat a character count times.

What is the right format-string to accomplish this?

EDIT: Yes, it is obvious that I could call printf() in a loop, but that is just what I wanted to avoid.

    Note that this format specifier will print a left substring of the input, so the number you use has to be <= the width of the string
