How do I make an if... else construct that reacts at a certain multiple of a number?

Question

I have an infinite loop, and would like to add an if...else loop that triggers when the loop is at the 10th, 20th, 30th, (aka a multiple of 10) time.

I'd like to know whether it's possible to make something like

if (x is the multiple of 10) printf(something)

else printf(something else)

Thanks!

If it's an infinite loop, when an (unsigned) counter wraps you'll get a discontinuity. Just count to 10 and reset the counter. — Weather Vane, Oct 12 '19 at 22:33

A number is a multiple of 10 if its remainder when dividing by 10 is 0. So use the modulus operator %:

if (x % 10 == 0) {
    // do something
} else {
    // do something else
}
