我用数组构架   写个类似贪吃蛇的东东求指点
如何实现  那条蛇的移动

赋值刷写屏幕字符

#include <stdio.h>
#include <windows.h>
#include <conio.h>
void gotoxy(HANDLE hout,int x,int y);     
int main()
{
    char input;                     
    int i,j,x=2,y=1;
    HANDLE hout;                        
    hout=GetStdHandle(STD_OUTPUT_HANDLE);
                  
    gotoxy(hout,2,2);               
    SetConsoleTextAttribute(hout,BACKGROUND_RED | BACKGROUND_INTENSITY);
    printf("  ");
    while (1)
    {
        SetConsoleTextAttribute(hout,FOREGROUND_GREEN | FOREGROUND_RED | FOREGROUND_INTENSITY);   
        gotoxy(hout,0,0);
        printf("亲，你瞧，有个红方块，用wasd可以控制移动哦！\n");
        SetConsoleTextAttribute(hout,BACKGROUND_GREEN | BACKGROUND_INTENSITY);      
        for (i=1,j=0;j<=16;j++)
        {
            gotoxy(hout,j*2,i);
            printf("  ");
        }
        for (i=10,j=0;j<=16;j++)
        {
            gotoxy(hout,j*2,i);
            printf("  ");
        }
        for (i=2,j=0;i<=10;i++)
        {
            gotoxy(hout,j,i);
            printf("  ");
        }
        for (i=2,j=32;i<=10;i++)
        {
            gotoxy(hout,j,i);
            printf("  ");
        }
        input=getch();               
        switch (input)
        {
        case 'w' :{if (x>2)  x--;};break;
        case 'a' :{if (y>1)  y--;};break;
        case 's' :{if (x<9)  x++;};break;
        case 'd' :{if (y<15) y++;};break;
        default: break;
        }
        SetConsoleTextAttribute(hout,0);      
        system("cls");                        
        gotoxy(hout,y*2,x);                     
        SetConsoleTextAttribute(hout,BACKGROUND_RED | BACKGROUND_INTENSITY);
        printf("  ");
   
    }
    return 0;
}
void gotoxy(HANDLE hout,int x,int y)
{
    COORD pos;
    pos.X=x;
    pos.Y=y;
    SetConsoleCursorPosition(hout,pos);
}
你运行一下试一试
