用c语言写出游戏俄罗斯方块的代码

以下是一个简单的用C语言写的俄罗斯方块游戏代码，供参考：

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

#define WIDTH 12
#define HEIGHT 22
#define SPEED 50

int board[HEIGHT][WIDTH] = {0}; // 游戏面板
int block[4][4] = {0}; // 当前方块
int block_x = 5, block_y = 0; // 当前方块的位置
int score = 0; // 得分

// 初始化游戏面板
void init_board() {
    int i, j;
    for (i = 0; i < HEIGHT; i++) {
        for (j = 0; j < WIDTH; j++) {
            if (i == HEIGHT - 1 || j == 0 || j == WIDTH - 1) {
                board[i][j] = 1;
            }
        }
    }
}

// 随机生成一个方块
void generate_block() {
    int type = rand() % 7;
    switch (type) {
        case 0:
            block[1][1] = block[1][2] = block[2][1] = block[2][2] = 1;
            break;
        case 1:
            block[1][0] = block[1][1] = block[1][2] = block[1][3] = 1;
            break;
        case 2:
            block[1][1] = block[2][1] = block[2][2] = block[3][2] = 1;
            break;
        case 3:
            block[1][2] = block[2][2] = block[3][1] = block[3][2] = 1;
            break;
        case 4:
            block[1][2] = block[2][1] = block[2][2] = block[3][1] = 1;
            break;
        case 5:
            block[1][2] = block[2][1] = block[2][2] = block[3][2] = 1;
            break;
        case 6:
            block[1][1] = block[2][1] = block[3][1] = block[3][2] = 1;
            break;
    }
}

// 在游戏面板上显示当前方块
void show_block() {
    int i, j;
    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {

            }
        }

// 消除满行
