// FILE: testget.cpp
// Written by Michael Main -- Nov 4, 1998
//
// Illustrates several features of the modified winbgim functions.
// To use these features, please download the newest versions of
// winbgim.h and winbgim.cpp as described in:
// http://www.cs.colorado.edu/~main/bgi/README.html
// Then create a project file that contains testget.cpp and winbgim.cpp.
// The project file should use have:
//   Target type: Application (exe)
//   Platform: Win32
//   Target model: Console
//   Using Static Libraries
//
// Compile and run the program to see:
//   1. Numbers that print in the graphics window.
//   2. Using the getch( ) function to get arrow and other special keys.
//
// Note:
//   winbgim contains its own versions of getch, delay, and kbhit.
//   You do not need to include conio.h to use these functions.
//   If you are going to print numbers to the graphics screen as shown below,
//   you do need to include stdio.h (which contains sprintf).

#include <cstdio>       // Provides sprintf
#include <iostream>     // Provides cout
#include <graphics.h>
