// Program to Add Many Integers

// input <- Prompted by the program, the user types zero or more integers.
// output-> The integers' sum is printed.

// We modified the previous program to add any number of integers.

// To add many integers, we must repeatedly ask for integers.  To do
// something repeatedly, we use a while loop.  First, we have to
// identify the lines that should be repeatedly executed.

#include <iostream.h>

int main()
{
  // This group looks a lot like ...
//  int first_integer;
//  cout << "Please enter an integer: ";
//  cin >> first_integer;

  // this group ...
//  int second_integer;
//  cout << "Please enter an integer: ";
//  cin >> second_integer;
  
  // so we put them inside the while loop.
  while (/* add test of when to stop */)
  {
    int second_integer;
    cout << "Please enter an integer: ";
    cin >> second_integer;
  }

  int sum = first_integer + second_integer;
  cout << "The sum is " << sum << ".\n";

  return 0;
