Operator Overloading is a programming feature that allows developers to redefine the behavior of standard operators (like +, -, *, etc.) for user-defined data types. This means that you can specify how these operators work when applied to objects of your own classes, making the code more intuitive and easier to read. For example, if you create a class called Vector, you can overload the + operator to add two Vector objects together. Instead of writing a separate method to handle vector addition, you can simply use the + operator, enhancing code clarity and usability.
