C语言写一个俄罗斯方块

俄罗斯方块是一种经典的游戏，使用C语言实现这个游戏需要一些基本的编程知识和技巧，下面是一个简单的代码实现，仅供参考：

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

#define WIDTH 10
#define HEIGHT 20

int brick[7][4][4] = {
    {{0, 0, 0, 0}, {1, 1, 1, 1}, {0, 0, 0, 0}, {0, 0, 0, 0}},  // I
    {{0, 0, 0, 0}, {0, 2, 2, 0}, {0, 2, 2, 0}, {0, 0, 0, 0}},  // O
    {{0, 0, 0, 0}, {0, 3, 3, 0}, {3, 3, 0, 0}, {0, 0, 0, 0}},  // Z
    {{0, 0, 0, 0}, {4, 4, 0, 0}, {0, 4, 4, 0}, {0, 0, 0, 0}},  // S
    {{0, 0, 0, 0}, {5, 5, 5, 0}, {0, 0, 5, 0}, {0, 0, 0, 0}},  // L
    {{0, 0, 0, 0}, {6, 6, 6, 0}, {6, 0, 0, 0}, {0, 0, 0, 0}},  // J
    {{0, 0, 0, 0}, {0, 7, 0, 0}, {7, 7, 7, 0}, {0, 0, 0, 0}}   // T

这个游戏的界面使用了控制台来显示，在Windows平台下可以直接使用，如果在其他平台上运行需要修改一些代码。
