What are the functions of overloading operators in C++?

The main purposes of C++ operator overloading are as follows:

  1. Enhancing the functionality of built-in data types: Custom operations can be defined for built-in data types (such as integers, floating-point numbers, etc.), giving them more versatility and functionality.
  2. Implementing operator overloading for class types: allows for defining operator overloads for class types, enabling support for more operations and enhancing the readability and maintainability of the code.
  3. Enhancing code readability: By properly defining operator overloading, code can be made more readable, intuitive, and understandable.
  4. Improve code reusability: Through operator overloading, existing code can be reused to reduce repetitive coding work and enhance code reusability.
  5. Perform specific operations: By defining specific operator overloads according to specific requirements, specific operations can be implemented to make the code more flexible and versatile.
