What are the different return types in C++?

What are the different return types in C++?

In C++, return types can be basic types like int, float, or double, as well as user-defined types like classes.

Can you explain how to use void as a return type?

Sure! A function with a void return type does not return a value. It's used when you want to perform an action without returning data.

What about returning pointers or references?

Returning pointers allows you to return the address of a variable, while references provide an alias to an existing variable, which can be more efficient.

Are there any best practices for choosing return types?

Yes, it's best to choose return types that match the function's purpose, use const references for large objects, and avoid returning local variables.
