Division is not working

Question

I've got a variable:

int Result = 42 % 84;

However its returning null on NSLog?

Answer 1

How does it return null in NSLog? Did you write "%@"?

Answer 2

int r=42%84;
NSLog(@"%d", r);

The above code logs 42 for me.

Answer 3

To NSLog an integer, use %d.

int result = 42 % 84;
NSLog(@"%d", result);
