用c++写一个俄罗斯方块

好的，我可以回答这个问题。以下是一个简单的俄罗斯方块的 C 代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <conio.h>
#include <windows.h>

#define WIDTH 10
#define HEIGHT 20
#define LEFT 75
#define RIGHT 77
#define UP 72
#define DOWN 80

int shapes[7][4][4] = {
    {{,,,},
     {1,1,1,1},
     {,,,},
     {,,,}},

    {{,,,},
     {,2,2,},
     {,2,2,},
     {,,,}},

    {{,,,},
     {,3,3,},
     {3,3,,},
     {,,,}},

    {{,,,},
     {4,4,,},
     {,4,4,},
     {,,,}},

    {{,,,},
     {,5,,},
     {5,5,5,},
     {,,,}},

    {{,,,},
     {,6,,},
     {,6,6,},
     {,6,,}},

    {{,,,},
     {,7,,},
     {,7,7,},
     {,,7,}}
};
