How do I use heterogeneous lookup with std::queue?

In C++, heterogeneous lookup allows us to access members of a class that can be found in types of different categories, such as base classes. This can be particularly useful when working with standard containers like `std::queue`.

Below is an example that demonstrates how to leverage heterogeneous lookup with `std::queue`. In this example, we have a base class `Base` and a derived class `Derived`. We create a queue of `Derived` objects and access members from both classes.


#include 
#include 

class Base {
public:
    void display() {
        std::cout << "I am Base class" << std::endl;
    }
};

class Derived : public Base {
public:
    void show() {
        std::cout << "I am Derived class" << std::endl;
    }
};

int main() {
    std::queue myQueue;
    Derived d1;
    myQueue.push(d1);
    
    // Accessing Derived class member
    myQueue.front().show();
    
    // Accessing Base class member
    myQueue.front().display();
    
    return 0;
}
