Basically + operator is binary operator, which performs on two buil in data types.

However if you wish to add two objects like complex numbers [ eg. (2+3i) + (4+6i) then its addition is (6+9i). In this case + operator needs to be overloaded with well defined code of adding both imaginary and real parts of numbers.

So in main(), you can directly write objC=objA+objB  (where objC,objA and objB all are complex number objects..)

Hence, this makes code readable and easy to maintain.

 

I hope you cleared your doubts...

Best luck..
