What are the best practices for operator overloading in C++?
When overloading operators in C++, it's important to follow certain best practices to ensure code clarity and maintainability. For instance, you should only overload operators when it makes logical sense for the types involved.
Can you give me some specific examples of operators that are commonly overloaded?
Sure! Commonly overloaded operators include +, -, *, / for arithmetic operations, and <<, >> for input and output streams.
Are there any operators that should not be overloaded?
Yes, operators like &&, ||, and , (comma) should generally not be overloaded as they can lead to confusion and unexpected behavior.
What about the return types for overloaded operators?
It's best to return by value for most operators, but for operators like = (assignment), you should return by reference to allow for chaining.
