C/C++ Code for Snake Game, with 3 lives & loading graphics

9 comments
/* Description of the Snake Game C/C++ code: It deals with a snake game. In this game snake goes to eat different blobs that are randomly popping on screen/dash board & if it eats that successfully, then it becomes larger in size & gains score. The player has the option of changing direction of the snake by pressing left, right, top, down arrows for moving the snake in desired direction.  This project was developed & compiled initially in Turbo C++ compiler & then with some modifications it was adapted to Microsoft Visual Studio, with some essential modifications*/

i get 'stdafx.h'; please tell me what is it ?

Vibhutesh Kumar Singh said...

If you are not using Visual Studio/C++ you dont need to use stdafx.h. So if its giving error please remove it.
