Question

As an example in pseudocode:

if ((a mod 2) == 0) {     isEven = true; } else {     isEven = false; } 

Answer 1

Instead of the modulo operator, which has slightly different semantics, for non-negative integers, you can use the remainder operator %. For your exact example:

if ((a % 2) == 0) {     isEven = true; } else {     isEven = false; } 

This can be simplified to a one-liner:

isEven = (a % 2) == 0;
