What do you mean by "working"? It does what the code says it does. (And 4%2 is not 2.) — Raymond Chen, Aug 19 '20 at 01:33

modulus operator (%) returns the remainder after (integer) division so 4 % 2 = 0 — Samuel Goldenbaum, Aug 19 '20 at 01:34

the % is for modulus and not for division.

in mathematics it defines the rest of a division, if a number is even divided by two the rest will equals 0 the modulus is commom used to find if a number is even or odd.

so it will work because 10 % 2 really equals 0

The % operator is not a division. It returns the remainder, for which 4 % 2 is 0.
