What is Polymorphism in C++?
------------------------------------------------
Polymorphism in C++ means, the same entity (function or object) behaves differently in different scenarios.
Consider this example:
The “ +” operator in c++ can perform two specific functions at two different scenarios i.e when the “+” operator is used in numbers, it performs addition.
int a = 6;
int b = 6;
int sum = a + b; // sum =12
And the same “+” operator is used in the string, it performs concatenation.
string firstName = "Great ";
string lastName = "Learning";
// name = "Great Learning "
string name = firstName + lastName;
Types of Polymorphism in C++
-------------------------------------------------
1. Compile Time Polymorphism
------------------------------------------------
In compile-time polymorphism, a function is called at the time of program compilation. We call this type of polymorphism as early binding or Static binding.
Function overloading and operator overloading is the type of Compile time polymorphism.
II. Operator Overloading
-----------------------------------------
Operator overloading means defining additional tasks to operators without changing its actual meaning. We do this by using operator function.
The purpose of operator overloading is to provide a special meaning to the user-defined data types.
The advantage of Operators overloading is to perform different operations on the same operand.
