// Tutorial 18: TicketInformation.cpp
// This application reads information about events on different
// dates from a file.
#include <iostream> // required to perform C++ stream I/O
#include <fstream>  // required to perform C++ file I/O
#include <string>   // required to access string functions
#include <cstdlib>  // required for the exit function

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

// function prototypes
int getDate();
void displayEvent( int );

// function main begins program execution
int main()
{
   int date; // event day

   // prompt user for and input the day for an event
   date = getDate();

   // display events (if any) and prompt user for new date
   while ( date != 0 )
   {
      date = getDate(); // prompt user for next event date
   } // end while

   cout << "\n"; // insert newline for readability
   
   return 0; // indicate that program ended successfully

} // end function main

// prompt user for and input date, then return the date if valid
int getDate()
{
   int date; // user input

   // prompt user for and input the requested date
   cout << "\nSelect date (1-31) or 0 to exit: ";
   cin >> date;

   // ensure that the date is valid before proceeding
   while ( date < 0 || date > 31 )
