Operator Overloading

C++ is a powerful language and I want to know about operator overloading .Can someone tell me the points to consider while doing or while using the concept of operator overloading.

This is a very big concept to put all the points. But to say in short for you Operator overloading is a concept in which a single operator can take up several functions as desired by programmers depending on the argument taken by the operator.

Here are some useful refferences. You'll get millions if you hit a google search.
