//Compile and Run-time polymorphism.

// Compile-time Polymorphism - static binding - early binding 
// function overloading  and operator overloading
// Non-virtual function binded at compile time

//Run-time polymorphism - late binding -dynamic binding
// Virtual Functions or function overriding
// Virtual function binded at runtime (Runtime polymorphism)
