But in term of programming for find even number we check remainder of number is zero or not, If remainder is equal to zero that means number. Integers which are perfectly divisible by 2 are called even numbers. And those integers which are not perfectly divisible by 2 are not known as odd number. To check whether an integer is even or odd, the remainder is calculated when it is divided by 2 using modulus operator %.
