The word polymorphism comes from two Greek words i.e., poly & morphism which means that same name but multiple form.
In programming language, Polymorphism means the name of elements to be same but having different properties. In simple words, suppose two functions have the same name but the definition of both the function are different. This concept is very useful in programming world.
Concept of Polymorphism in programming,
- Function Overloading
- Operator Overloading
Function Overloading
Function overloading is a feature of object oriented programming which allows us to create two or more than two function with same name but the condition is that there behavior and there parameters have to be different.
For example,
Suppose two function are there with the same name area() but one area() is for finding the area of circle and one are is for finding the area of the perimeter.
Operator Overloading
Operator Overloading is a feature of object oriented programming which allows to give different definition to the same operator.
For Example,
Suppose the same operator + may used for addition of two number and also used for concatenation of two strings.
