Operator overloading facilitates the specification of user-defined implementation for operations wherein one or both operands are of user-defined class or structure type . This helps user-defined types to behave much like the fundamental primitive data types.

However, when you overload a binary operator, the corresponding compound assignment operator , if any, is also implicitly overloaded. For example, += is evaluated using + , which can be overloaded. These operators cannot be overloaded. The comparison operators must be overloaded in pairs.

Polymorphism: Polymorphism (or operator overloading) is a manner in which OO systems allow the same operator name or symbol to be used for multiple operations . That is, it allows the operator symbol or name to be bound to more than one implementation of the operator. A simple example of this is the “+” sign.

It is polymorphism in which an operator is overloaded to give user defined meaning to it . Overloaded operator is used to perform operation on user-defined data type. For example ‘+’ operator can be overloaded to perform addition on various data types, like for Integer, String(concatenation) etc.
