What are some examples of function overloading in C++ classes?

Can you explain function overloading in C++ with some examples?

Sure! Function overloading allows multiple functions to have the same name but different parameters. For example, you can have a function named 'add' that adds two integers and another 'add' that adds two doubles.

Can you show me a code example of that?

Absolutely! Here's a simple example:

class Calculator {
public:
    int add(int a, int b) {
        return a + b;
    }
    double add(double a, double b) {
        return a + b;
    }
};

In this class, the 'add' function is overloaded to handle both integers and doubles.

What happens if I try to call add with a string?

If you try to call 'add' with a string, it will result in a compilation error because there is no matching overloaded function for that type.

Are there any limitations to function overloading?

Yes, function overloading can lead to ambiguity if the parameters are not distinct enough. For example, if you have two functions that take a single parameter of different types, the compiler may not know which one to call.
