// Tutorial 16: PassByReference.cpp
// This application demonstrates passing by reference using
// reference arguments and pointer arguments.
#include <iostream> // required to perform C++ stream I/O

using namespace std; // for accessing C++ Standard Library members

// function main begins program execution
int main()
{
   int input = 0; // integer to be passed by reference

   // prompt the user for and input an integer
   cout << "\nEnter an integer: ";
   cin >> input;

   cout << endl; // insert newline for readability

   return 0; // indicate that program ended successfully

} // end function main
