Modulus operator are useful in many circumstances and it is commonly used to generate the random number. It basically reduce the number into random number in a small range.

It also describe that whether, the one number is a factor of another or not.

In C language, the modulus operator provide the remainder after diving the greater value with the smaller value. If the smaller number are divided by the larger number then, the quotient become zero.
