Seperating C++ Code Into Multiple Files

I have the below code in one file.

I need to seperate it into the below files.

Please tell me how to seperate it and what goes in which file.

FIles that i need to seperate below code into:

1. heap.h - declaration file for heap.

2. heap.cpp - implementation file for heap.

3. pqtype.h - declaration file for priority queue.

4. pqtype.cpp - implementation file for priority queue.

5. test.cpp - driver file.

Code i currently have in one file:

#include #include #include #include #include

using namespace std;

struct node { int priority; int snumber; string jobName; struct node *next; };

class PriorityQueue { private: node *front; public:

PriorityQueue() { front = NULL; }

void addJob(string item, int priority, int number)

{ node *temp, *q; temp = new node; temp->jobName = item; temp->priority = priority; temp->snumber = number; //whether queue is empty

if (front == NULL || priority < front->priority) { temp->next = front; front = temp; } else { q = front; while (q->next != NULL && q->next->priority <= priority) q = q->next; temp->next = q->next; q->next = temp; } }

void printJob()

{ node *temp; if (front == NULL) cout << "No print jobs in queue. "; else { temp = front; cout << "Now printing Job # " << temp->snumber << " " << temp->jobName << endl; front = front->next; free(temp); } }

void viewJob() { node *ptr; ptr = front; if (front == NULL) cout << "No print jobs in queue "; else { while (ptr != NULL) { cout << "Job #: " << ptr->snumber << " " << ptr->jobName << endl; ptr = ptr->next; } } } };

int main() { int choice, priority; PriorityQueue pq; char ch; string jobName; int number = 0; cout << "Printer queue" << endl; cout << "=============" << endl; do { cout << " 1.Add Job "; cout << "2.Print Job "; cout << "3.View Job "; cout << "4.Exit "; cout << "Enter choice : "; cin >> choice;

switch (choice) { case 1: cout << "Instructor (I or i), TA (T or t), or Student (S or s)? "; cin >> ch; if (ch == 'i' || ch == 'I') { priority = 1; jobName = "Instructor"; } else if (ch == 't' || ch == 'T') { priority = 2; jobName = "TA"; } else if (ch == 's' || ch == 'S') { priority = 3; jobName = "Student"; } number++; pq.addJob(jobName, priority, number); break;

case 2: pq.printJob(); break; case 3: pq.viewJob(); break; case 4: break; default: cout << "Invalid choice. "; } } while (choice != 4); system("PAUSE"); return 0; }
