无法将参数 1 从“const char [13]”转换为“const wchar_t ” c:\users\
类型不一样不可以转换哦, 一个是char ,一个是 wchar_t ,当然不能转换
建议你学习炫彩界面库, 比MFC简单, 好多年不用MFC了
达到你说的要求，可以使用kbhit()函数，上百度搜一下它的用法，这个函数可以检测到游戏中是否有按键被按下，如果没有就使用一个死循环使蛇身一直移动，如果检测到了有按键被按下，就判断是否是方向键或者程序中设置的其他功能键(如ESC退出键，调速键等)，如果不是，不做响应，如果是，就就bioskey()函数接收这个键，并根据这个键值做出相应的响应！
写游戏要注意模块化，你这样全写在main里很乱的。
使用数组解决贪吃蛇的问题有点挠头，最好是自己构造一个合适的数据类型。
还有就是学习一下<graphicsh>这个头文件，只需要里面的几个函数就可以设计贪吃蛇的图形界面。
给你个现成的贪吃蛇游戏，代码不长，仔细看一下里面的数据结构和算法思想。

这个程序有只有一个地方需要改，就是initgraph(&gd,&gm,"c:\\JMSOFT\\DRV");
这句代码中的第三个参数是 bgi文件的路径，你按下键盘上的alt + f 搜索一下 bgi在哪个目录下，把那个路径复制到这个地方就可以了直接运行了，不然可能提示你 初始化错误!。
可以Sleep函数设置延时来控制贪吃蛇的速度。
函数名： Sleep
功 能： 执行挂起一段时间
用 法： void Sleep(DWORD dwMilliseconds);
在VC中使用带上头文件
#include <windowsh>
（ Sleep函数存放头文件：WinBaseh）
在gcc编译器中，使用的头文件因gcc版本的不同而不同
#include <unistdh>
Sleep()单位为毫秒，sleep()单位为秒（如果需要更精确可以用usleep单位为微秒）
返回值
若进程/线程挂起到参数所指定的时间则返回0，若有信号中断则返回剩余秒数。
