what is operator overloading? what are the benefits of operator overloading?

Operator overloading in C++ is a feature that allows operator such as "+" or "-" to be redefined to work with user-defined datatypes, such as classes. In other words, it allows you to change the way that an operator works when applied to instances of a class.

The benefits of operator overloading are as follows:

1. Improved readability: overloading an operator can make code more readable as it can make it easier to understand the intent of the code.

2. Consistency: By overloading operators for a class, you can ensure that the syntax and behavior of the operators are consistent with the rest of the language, making it easier for other programmers to understand and use your code.

3. Increased flexibility: Overloading operators can make it easier to implement new types of objects and behaviors, as well as make it easier to extend existing classes.

4. Better performance: In some cases, operator overloading can lead to improved performance compared to using equivalent non-overloaded methods, as the compiler can optimize the code when it knows the exact types of the operands.
