Operator overloading concept, Overloading binary operator +, operator overloading using a friend function.
Specifying more than one definition for an operator in the same scope is called operator overloading.
You can overload operators by creating “operator functions”.
Operator overloading extends the overloading concept to operators, letting you assign multiple meanings to C++ operators.
Operator overloading giving the normal C++ operators such as +, * and == additional meanings when they are applied with user-defined data types.
Some of C++ Operators are already overloaded.
Operator overloading is compile time polymorphism.
The only existing operator can be overloaded.
The overloaded operator must have at least one operand that is a user-defined type.
We cannot change the basic meaning and syntax of an operator.
