c语言俄罗斯方块代码

以下是一个简单的C语言俄罗斯方块代码示例：

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

#define WIDTH 12     // 画面宽度
#define HEIGHT 22    // 画面高度
#define BLOCK_SIZE 4 // 方块大小
#define BLOCK_NUM 7  // 方块数量

int block[BLOCK_NUM][BLOCK_SIZE][BLOCK_SIZE] = {
    // I
    {
        {0, 0, 0, 0},
        {1, 1, 1, 1},
        {0, 0, 0, 0},
        {0, 0, 0, 0}
    },
    // J

        {1, 1, 1},
        {0, 0, 0}
    },

    {

        {1, 1}
    },
    // S
    {
        {0, 1, 1},
        {1, 1, 0},

以上代码实现了一个简单的俄罗斯方块游戏，使用了控制台窗口作为画面，通过键盘输入控制方块移动和旋转。
