What are some common mistakes in function overloading in C++?

Some common mistakes include using different return types, not considering const qualifiers, and failing to account for type promotions.

Can you explain why using different return types is a mistake?

Using different return types doesn't help in function overloading because the compiler cannot differentiate between functions based solely on return type.

What about const qualifiers? How do they affect overloading?

Const qualifiers can lead to ambiguity if overloaded functions differ only by constness, making it hard for the compiler to choose the correct one.

Are there any best practices to avoid these mistakes?

Yes, always ensure that overloaded functions differ by parameter types or number, and avoid relying on return types or const qualifiers.
