Question

Can someone help me with C++? I have to implement a priorityQueue Linked List.

//////////////////////////////////////////

driver.cpp

//////////////////////////////////////////

#include <iostream>
#include <string>
#include "stackLL.h"
#include "queueLL.h"
#include "priorityQueueLL.h"
using namespace std;

int main()
{

    //////////Test code for priority queue/////

priorityQueueLL<int> pQueue;

    const int SIZE = 20;

    //insert a bunch of random numbers
    for (int i = 0; i < SIZE; i++)
    {
        pQueue.insert(rand());
    }

    //pull them back out..
    //They must come out in order from smallest to largest
    while (!pQueue.empty())
    {
        cout << pQueue.extractMin() << endl;
    }


    priorityQueueLL<string> pqs;

    pqs.insert("whale");
    pqs.insert("snake");
    pqs.insert("buffalo");
    pqs.insert("elmo");
    pqs.insert("fire");
    pqs.insert("waffle");

    //buffalo elmo fire snake waffle whale
    while (!pqs.empty())
    {
        cout << pqs.extractMin() << endl;
    }

    return 0;
}
