}贪吃蛇源程序
这个程序在VC++中执行时提示#include <graphics.h>有问题
请问应该怎么调试?

Answer 1

VC++编译环境没有graphics.h头文件，你必须在TC环境下运行！另外你的程序缺少GameOver()函数，而且void GamePlay(void)函数中缺少多个右花括号}。
给你一个编得不错的贪吃蛇，在TC环境下运行！

Answer 2

这个程序是按C言语中的函数库编的。graphics.h是基于dos的图形库,是turbo c/c++的专门库的一个头文件，用来定义borland绘图功能的函数。
要调试的话，改的太多了。一时半会我也改不过来。
VC也有自带的绘图函数库。有时间会去给你改改。
