Polymorphism is the ability of an object to exhibit multiple behaviors. C++ allows two types of polymorphism, Static and Dynamic. Static polymorphism happens at compile time via function overloading whereas Dynamic polymorphism is exhibited at run time via function overriding.

Softwares are susceptible to change. A new requirement can come-up any time and the software should be able to handle this change effectively with minimum intrusion. A software that is well designed can easily adapt to these ever-changing requirements and hence a good design is of utmost importance especially when it comes to design and development of a commercial software.
