What are the best practices for overloading functions in C++?

When overloading functions in C++, ensure that the function signatures differ in the number or type of parameters. This helps avoid ambiguity.

Can you give me an example of function overloading?

Sure! For instance, you can overload a function named 'add' to handle both integers and doubles:

int add(int a, int b) {
    return a + b;
}

double add(double a, double b) {
    return a + b;
}

Are there any common mistakes to avoid when overloading?

Yes, a common mistake is to overload functions with the same name but identical parameter types, as this leads to ambiguity.

What about operator overloading? Any tips?

For operator overloading, ensure that the operation makes sense for the types involved and maintain intuitive behavior. Always follow the principle of least surprise.
