What are the rules for function overloading in C++?

What are the rules for function overloading in C++?

Function overloading in C++ allows multiple functions with the same name but different parameters. The rules include: 1. Different number of parameters. 2. Different types of parameters. 3. Different order of parameters.

Can you give me an example of function overloading?

Sure! Here's an example:

void display(int a) {
    cout << "Integer: " << a << endl;
}

void display(double b) {
    cout << "Double: " << b << endl;
}

void display(string c) {
    cout << "String: " << c << endl;
}

In this case, the function display is overloaded with different parameter types.

Are there any limitations to function overloading?

Yes, there are limitations. You cannot overload functions based solely on return type, and the parameters must differ in type or number.

What happens if I overload a function incorrectly?

If you overload a function incorrectly, the compiler will throw an error indicating that it cannot resolve which function to call due to ambiguity.
