why to use operator overloading..

Answer / chandra

to achieve synchronization with the normal languages like c.
for example int a=10,b=30,c;
c = a+b ;
the above operation is possible in c as well as c++.bcos
the variables declared are primitive types.

If u want to do same thing for user defined datatypes, i
can say objects, we have to overload the operators.

For ex:
Assume that u created one class
Class A
and u have created objects
A obj1(10),obj2(30),obj3;

and u want the add 2 objects and result must be stored in
another object.

then u have to overload the operator + for class A.

obj3 = obj1 + obj2 ;
