Infinite loop when using size_t in a count down for loop

Question

So I\'m using size_t instead of int in any indexing for loop to prevent negative indices. But when counting down, this leads to an overflow:

<

Answer 1

for (size_t i = 11; i-- > 0; ) {
    // Do something, f.ex. array[i] = i
}

Note: The question starts the loop with value=10(which is strange, but not impossible). I start with 11, but the first time the loop body is enterered, it has already been decremented to 10.
