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 types of parameters.

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 pitfalls to avoid when overloading?

Yes, avoid ambiguous overloads where the compiler cannot determine which function to call. Also, be cautious with default arguments.

What about operator overloading? Any tips?

For operator overloading, ensure that the operation makes sense for the type and maintain intuitive behavior. Use friend functions for access if needed.
