Question

I have noticed that when using for loop in objective c, i cant set the loop to go down like:

for(int i=16; i<=1; i-- )
    {
        NSLog(@"%d",i);
    }

He would not print i .
How can i do that anyway ?

Answer 1

Your for statement is incorrect, you check (second part of the for) i<=1. This defines while i is smaller or equal to 1 and this should be i>=1: while i is larger or equal to 1.

for(int i=16; i>=1; i-- )
{
    NSLog(@"%d",i);
}
