Simply speaking, polymorphism is the ability of something to be displayed in multiple forms. Let’s take a real life scenario; a person at the same time can perform several duties as per demand, in the particular scenario. Such as, a man at a same time can serve as a father, as a husband, as a son, and as an employee. So, single person possess different behaviors in respective situations. This is the real life example of polymorphism. Polymorphism is one of the important features of Object Oriented Programming (OOP).
The C and C++ language provides a built-in mechanism, the modulus operator (‘%’), that computes the remainder that results from performing integer division.
