objective-C question

for(int m=1;m <= 200; m++){
        int divisibleByFive;
        divisibleByFive = 5;
        NSLog(@"%d", m);

        if((m % divisibleByFive) == 0) {
            NSLog(@"divisible by %d = %d",divisibleByFive, m);
        }
    }

I coded this and still don't understand the if statement's condition. why is it is-equal to 0, to get the divisibility. Thanks!

Hi!

The result of "m % divisibleByFive" is the remainder of the division (not the quotient as you might think). So the if statemen says: If the remainder of some number divided by 5 is 0 that means is a divisible number, everything else (a remainder from 1 to 4 in this case) is not divisible.
