Testing Your Queue

If you build out your own queue, use this main function to test your code to ensure everything is working properly:

#include "QueueUsingStacks.h"

using namespace std;

int main() {
    QueueUsingStacks queue;

    // Test enqueue operation
    queue.enqueue(1);
    queue.enqueue(2);
    queue.enqueue(3);
    cout << "After enqueue operations:\n";
    queue.display();

    // Test dequeue operation
    cout << "Dequeued: " << queue.dequeue() << "\n";
    cout << "After one dequeue operation:\n";
    queue.display();

    // Test front operation
    cout << "Front of the queue: " << queue.front() << "\n";

    // Test more enqueue and dequeue operations
    queue.enqueue(4);
    queue.enqueue(5);
    cout << "After adding more elements:\n";
    queue.display();

    cout << "Dequeued: " << queue.dequeue() << "\n";
    cout << "Dequeued: " << queue.dequeue() << "\n";
    cout << "After two more dequeue operations:\n";
    queue.display();

    // Test isEmpty
    cout << "Is the queue empty? " << (queue.isEmpty() ? "Yes" : "No") << "\n";

    return 0;
