Unsigned int reverse iteration with for loops

Question

I want the iterator variable in a for loop to reverse iterate to 0 as an unsigned int, and I cannot think of a similar comparison to i > -1, as

Answer 1

My pattern for this is usually...

for( unsigned int i_plus_one = n; i_plus_one > 0; --i_plus_one )
{
    const unsigned int i = i_plus_one - 1;
    // ...
}
