What is the purpose of operator overloading in C#?

Operators overloading in C# allows programmers to redefine the behavior of operators to fit specific data types or classes. By overloading operators, user-defined classes can have similar behaviors to built-in data types, making the code more flexible and easier to understand. For example, overloading the addition operator can be used to implement the addition operation of two objects, or overloading comparison operators can define comparison rules between objects. Through operator overloading, code readability and maintainability can be improved.
