What is the difference between function overloading and function overriding in C++?

Can you explain the difference between function overloading and function overriding in C++?

Sure! Function overloading allows multiple functions with the same name but different parameters, while function overriding is when a derived class has a function with the same name and parameters as a base class.

Can you give me an example of function overloading?

Of course! Here's a simple example:

class Print {
public:
    void display(int i) {
        std::cout << "Integer: " << i << std::endl;
    }
    void display(double d) {
        std::cout << "Double: " << d << std::endl;
    }
};

In this case, the display function is overloaded to handle both integers and doubles.

What about function overriding? Can you show me that too?

Certainly! Here's an example of function overriding:

class Base {
public:
    virtual void show() {
        std::cout << "Base class show function." << std::endl;
    }
};

class Derived : public Base {
public:
    void show() override {
        std::cout << "Derived class show function." << std::endl;
    }
};

In this example, the show function in the Derived class overrides the show function in the Base class.

Thanks! That really clarifies things.
