#include <iostream>
#include <string>

 using namespace std;

 int swap_value(int *a, int *b, int temp)
  temp = *a;
  *a = *b;
  *b = temp;

 main() {

     int a=0,b=0,temp=0;
      char reply = 'Y';

 for (; toupper(reply)== 'Y'; ) {

 cout << "\n\n";
 cout << "\n\n\t Created By: Mr. Jake R. Pomperada,MAED-IT";
 cout << "\n\n";
 cout << "Enter the first value  :=> ";
 cin >> a;
 cout << "Enter the second value :=> ";
 cin >> b;

 cout << "\nOrignal value of a : " << a <<".";
 cout << "\nOrignal value of b : " << b <<".";

 cout << "\n\n";

 cout << "After calling the function Reference/Pointer";
 cout << "\n\n";

 cout << "\nNew value of a : " << a <<".";
 cout << "\nNew value of b : " << b <<".";
 cout << "\n\n";
 cout << "Do You Want To Continue Y/N :=> ";
 cin >> reply;

 if (toupper(reply) == 'N') {
     cout << "\nThank You For Using This Program.";

 cout << "\n\n";
