c语言编写俄罗斯方块程序

以下是一个简单的C语言实现俄罗斯方块的程序，供您参考：

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

#define WIDTH 10
#define HEIGHT 20

int map[HEIGHT][WIDTH] = {0}; // 地图数组，0表示空，1表示有方块
int block[4][4] = {0}; // 方块数组，0表示空，1表示有方块
int block_x = 0, block_y = 0; // 方块左上角坐标
int score = 0; // 得分

// 画地图
void draw_map() {
    system("cls"); // 清屏
    printf("Score: %d\n", score);
    for (int i = 0; i < HEIGHT; i++) {
        for (int j = 0; j < WIDTH; j++) {
            if (map[i][j] == 0) {
                printf(".");
            } else {
                printf("*");
            }
        }
        printf("\n");
    }
}

// 生成新方块
void new_block() {
    int type = rand() % 7; // 随机生成方块类型
    switch (type) {
        case 0: // I型
            block[0][1] = block[1][1] = block[2][1] = block[3][1] = 1;
