To understand the concept of = operator, take the scenario, i = j = k; In this k should be assigned to j and then j should be assigned to i. This is the reason, why we make the return type of the =operator as reference and not by value. If you are passing by value, u will have problem, if u have a pointer data member and u are allocating new memory and don't have a copy constructor. By using return by reference you are actually saving on time as well as memory. Rahul
