Question

can you add based on code below to prints the time when the print job from each student started and their waiting time. It also need to calculate the time needed to complete all printing jobs and the average waiting time. all using dynamic queue.

 

#include <bits/stdc++.h>
using namespace std;

struct QNode {
    int data;
    QNode* next;
    QNode(int d)
    {
        data = d;
        next = NULL;
    }
};

struct Queue {
    QNode *front, *rear;
    Queue()
    {
        front = rear = NULL;
    }

    void enQueue(int x)
    {

        // Create a new LL node
        QNode* temp = new QNode(x);

        // If queue is empty, then
        // new node is front and rear both
        if (rear == NULL) {
            front = rear = temp;
            return;
        }

        // Add the new node at
        // the end of queue and change rear
        rear->next = temp;
        rear = temp;
    }

    // Function to remove
    // a key from given queue q
    void deQueue()
    {
        // If queue is empty, return NULL.
        if (front == NULL)
            return;

        // Store previous front and
        // move front one node ahead
        QNode* temp = front;
        front = front->next;

        // If front becomes NULL, then
        // change rear also as NULL
        if (front == NULL)
            rear = NULL;

        delete (temp);
    }
};

// Driven Program
int main()
{

    Queue q;
    q.enQueue(10);
    q.enQueue(20);
    q.deQueue();
    q.deQueue();
    q.enQueue(30);
    q.enQueue(40);
    q.enQueue(50);
    q.deQueue();
    cout << "Queue Front : " << (q.front)->data << endl;
    cout << "Queue Rear : " << (q.rear)->data;
}

Consider the following situation in a computer science laboratory. On any average day
about 10 students are working in the lab at any given hour. These students uses the
shared printer in the lab to print their assignments and reading materials. The time
taken for printing tasks varies from one another depending on the pages volumes
printed by students. Students can send printing instructions from any terminals
attached to same network of the printer. Hence, many students can do so at once.
Below is the six printing job (each labelled as Task ID) that await to be printed along
with their printing time and arrival time. Note that time unit starts with to.

Explain how can the printer handles the many instructions. Show your solution in terms
of flowchart and full program.
Make sure your program use dynamic queue as the data strcuture and simulates
the whole executions till completion. Your program should prints the time when the
print job from each student started and their waiting time. It also need to calculate the
time needed to complete all printing jobs and the average waiting time.
