用 c语言写个俄罗斯方块程序

好的，下面是一个基于C语言的简单俄罗斯方块程序：

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

#define WIDTH 10
#define HEIGHT 20

int board[HEIGHT][WIDTH] = {0}; //初始化游戏面板
int block[4][4] = {0}; //初始化方块

//生成随机方块
void generate_block() {
    int idx = rand() % 7;
    int blocks[7][4][4] = {
        {{0,0,0,0},
         {1,1,1,1},
         {0,0,0,0},
         {0,0,0,0}},
        {{0,0,0,0},
         {0,1,1,0},
         {0,1,1,0},
         {0,0,0,0}},
        {{0,0,0,0},
         {1,1,0,0},
         {0,1,1,0},
         {0,0,0,0}},
        {{0,0,0,0},
         {0,1,1,0},
         {1,1,0,0},
         {0,0,0,0}},
        {{0,0,0,0},
         {0,1,0,0},
         {1,1,1,0},
         {0,0,0,0}},
        {{0,0,0,0},
         {1,0,0,0},
         {1,1,1,0},
         {0,0,0,0}},
        {{0,0,0,0},
         {0,0,1,0},
         {1,1,1,0},
         {0,0,0,0}}
    };
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            block[i][j] = blocks[idx][i][j];
        }
    }
}

//判断方块是否可以放置
int can_put_block(int x, int y) {
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            if (block[i][j] == 1) {
                int px = x + j;
                int py = y + i;
                if (px < 0 || px >= WIDTH || py < 0 || py >= HEIGHT || board[py][px] != 0) {
                    return 0;
                }
            }
        }
    }
    return 1;
}

//将方块放置到游戏面板上
void put_block(int x, int y) {
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            if (block[i][j] == 1) {
                board[y+i][x+j] = 1;
            }
        }
    }
}

//消除满行
void clear_full_rows() {
    for (int i = 0; i < HEIGHT; i++) {
        int is_full = 1;
        for (int j = 0; j < WIDTH; j++) {
            if (board[i][j] == 0) {
                is_full = 0;
                break;
            }
        }
        if (is_full) {
            for (int k = i; k > 0; k--) {
                for (int j = 0; j < WIDTH; j++) {
                    board[k][j] = board[k-1][j];
                }
            }
            for (int j = 0; j < WIDTH; j++) {
                board[0][j] = 0;
            }
        }
    }
}

//绘制游戏面板
void draw_board() {
    system("cls"); //清屏
    for (int i = 0; i < HEIGHT; i++) {
        for (int j = 0; j < WIDTH; j++) {
            printf("%c", board[i][j] == 0 ? ' ' : '*');
        }
        printf("\n");
    }
}

int main() {
    srand(time(NULL)); //初始化随机数生成器
    while (1) {
        generate_block(); //生成随机方块
        int x = 3;
        int y = 0;
        while (can_put_block(x, y)) { //如果方块可以放置
            draw_board(); //绘制游戏面板
            Sleep(100); //暂停100毫秒
            y++; //方块下落
        }
        y--; //方块无法再下落时回退一格
        put_block(x, y); //将方块放置到游戏面板上
        clear_full_rows(); //消除满行
    }
    return 0;
}

这个程序使用了Windows API中的Sleep函数来实现暂停，如果在其他平台上运行，需要使用相应的函数来实现暂停。
