Modify the program (code) such that the user can run it as many time as he/she wants.

You should provide digital and hard copy of your work.

#include <iostream>

#include <string>

using namespace std;

int main(int argc, char **argv)

{

            string input;

            int count = 0, length ;

                       

            cout <<" Enter your phrase:"<<endl;

            getline (cin, input);

            length = (int) input.length ();

            for (count = 0; count < length; count++)

            {

                        if (isalpha (input [count]))

                        {                     

                                    for (int i = 0; i < 12; i++)

                                    {

                                                if (input [count] == 'z')

                                                            input [count] = 'a' ;

                                                else

                                                            input[count] ++;

                                    }

                        }

            }

            cout << " Results: \n" << input<<endl;                      

    system("PAUSE");

    return EXIT_SUCCESS;
