How to you print % in a string, as in I want the print out looking like, "6 % 2 = ..."?

How do I print something that looks like

"6 % 2 = 0"

I'm trying,

NSLog(@"6 % 2 = %d", 6 % 2);

but am getting 2 errors. More percent conversions that data arguments and invalid conversion specifier.

I need to type instead NSLog(@"6 %% 2 = %d", 6 % 2);

but why do I need two %%s?

Thanks!

The % character is part of a format specifier such as %f or %d. If you want to print a % in a string you need to use the escape code %%. You can visit Mac Developer Library for more information about string formatting.
