Overloading means that the same operator, method maybe used
for different purposes.
It is part of the OOP concept 'Polymorphism'.
1)Method overloading:Methods with same name, but different
argument types and number of arguments.
2)Operator overloading: Same operator can be used for
different ways, ex:'+' can be used for addition and for
concatenation.
3)Constructor overloading: We can define two constructors
for a same class, ie with same name, but difference in
argument types and number of arguments.
