The purpose of operator overloading is to provide a special meaning of an operator for a user-defined data type. With the help of operator overloading, you can redefine the majority of the C++ operators. You can also use operator overloading to perform different operations using one operator.

Why do we need operator overloading?

The need for operator overloading: It allows us to provide an intuitive interface to our class users, plus makes it possible for templates to work equally well with classes and built-in types. Operator overloading allows C++ operators to have user-defined meanings on user-defined types or classes.
