C語言寫的簡單貪喫蛇程序，實現WASD控制蛇運動，輸入輸出流爲C++

其實還是比較簡單的，總的來說就是運行的時候注意上下左右調整爲大寫輸入，

WASD控制上下左右，
在程序內部有解釋程序的構造。

# include "snack.h"

int main()
{
    int counter = 50;
    InitFrame();
    Wall();
    InitSnack();
    Create_apple();
    char ch = 'D';
    char ch1 = ch;
    while(1)
    {
        Handle(0,N+2);
        if(_kbhit())//判斷是否鍵入
        {

            ch = _getch();
            if(!(ch1 == ch+3 || ch1 == ch-3 || ch1 == ch+4 || ch1 == ch-4))//判斷
             ch1 = ch;
            Shift_Snack(ch1);
            counter = 0;

        }
        else{
                Sleep(10);
                counter++;
        }
        if(counter >= 50)
        {
            Shift_Snack(ch1);
            counter = 0;

        }
        if (flag_1 == 0)
            break;
    }
    //getchar();
    Handle(0,N+2);
    return 0;
