/* Author: <Removed> Created in Spring 2004 This is the classic game of Snake. The object of the game is to eat the food that appears on the board, which increases the length of your snake by a factor of one. Your score is the amount of additional lengths you aquire before losing. You lose by either running into yourself or into a barrier or wall. I created this game for my end-of-the-year project in Computer Science II for my senior year of high school. I used Borland C++ 5.02 to create and compile this program. Thank you to my Computer Science I and II teacher, <Removed>. She has taught me me everything I know, supports me 100%, and continues to challenge me. Also Thanks to Mohammed Ali Akbani for creating the In9.h header file and releasing it as freeware. This header file was "key" to my program. */ #include <iostream.h> #include <conio.h> #include <stdlib.h> #include <time.h> #include <dos.h> #include <stdio.h> #include <fstream.h> #include <windows.h> #include "dosgraphics.h" #include "int9.h" int num;
