I am inputing from a text file, displaying it on the screen, displaying the menus and the choosing from there. It will repeat the menu, but, how to do I get it to read the next line in my input file and display it to the screen before repeating the menu?

Here's what I have.

#include <iostream>
#include <iomanip>
#include <fstream>
#include <cstdlib>

using namespace std;

//Function Prototypes
void accept (char letter);
void transfer (char letter);
void decline (char letter);
int menu ();

int main()
{
        
    
    const int SIZE = 100; //Length of line
    char first[SIZE], last[SIZE], phone[SIZE], status;
    int X, pref;
    
    ifstream inputFile; //File Stream Object
    inputFile.open ("c:\\potentials.txt", ios::in);  //Open File
    
   
    if (inputFile.fail()) //Error Opening File
   { 
      cout << "Error opening file. The file could not be found.\n";
      cout <<""<<endl;
      system ("PAUSE");
      return EXIT_FAILURE;  
   }

    // Determine status
    inputFile >> status;
    if (status == 'X' || status == 'x')
   {
      cout << "Preferred -- 7.9%" << endl;
      pref=0;
   }  
    else 
   {
      cout << "12.9%" << endl; 
      pref=1;
   }
    
    // Get name
    inputFile >> first >> last;
    cout << first << " " << last << endl;    
    
    // Get phone number
    inputFile >> phone;
    cout << phone << endl;
    cout << "" << endl;

   char letter;
    
    do
    {
        letter = menu ();
        switch (letter)
        {
            case 'A':  accept ('A');
                       break; 
            case 'a':  accept ('a');
                       break;

Place all the code you want to repeat each time new stuff is read from the file inside the body of a loop, maybe lines 34 through 76, or something like that. Use line 35 as the controlling condition for the loop to run by placing it between the parenthesis of a while loop.
