Polymorphism

- What is polymorphism?
 -. Polymorphism word came from greek. we can divide the polymorphism word in two parts
	first part - poly means many and
	second pard - morphism meand forms
	so it means many forms.

- so in software/coding/ programming we can do  a method can be transform in many forms.
