用C语言编写给200个新生随机分配50个宿舍小程序。 （已知楼号，房号；学生学号，班级，性别等信息）

以下是基于C语言的一个简单实现：

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

#define FLOOR_NUM 5 // 楼层数
#define ROOM_NUM 10 // 每层房间数
#define ROOM_CAPACITY 5 // 房间容纳人数

// 学生信息结构体
typedef struct {
    char id[10]; // 学号
    char class[10]; // 班级
    char gender[10]; // 性别
} StudentInfo;

// 房间信息结构体
typedef struct {
    int floor; // 楼层
    int room; // 房间号
    int cur_capacity; // 当前房间人数
    StudentInfo students[ROOM_CAPACITY]; // 学生信息数组
} RoomInfo;

// 初始化房间信息数组
void initRooms(RoomInfo rooms[FLOOR_NUM][ROOM_NUM]) {
    for (int i = 0; i < FLOOR_NUM; i++) {
        for (int j = 0; j < ROOM_NUM; j++) {
            rooms[i][j].floor = i + 1;
            rooms[i][j].room = j + 1;
            rooms[i][j].cur_capacity = 0;
        }
    }
}

// 随机分配宿舍
void assignRooms(RoomInfo rooms[FLOOR_NUM][ROOM_NUM], StudentInfo students[], int student_num) {
    for (int i = 0; i < student_num; i++) {
        int floor, room;
        do {
            floor = rand() % FLOOR_NUM;
            room = rand() % ROOM_NUM;
        } while (rooms[floor][room].cur_capacity == ROOM_CAPACITY); // 直到找到空房间

        // 将学生信息添加到房间中
        rooms[floor][room].students[rooms[floor][room].cur_capacity] = students[i];
        rooms[floor][room].cur_capacity++;
    }
}

// 输出房间分配结果
void printRooms(RoomInfo rooms[FLOOR_NUM][ROOM_NUM]) {
    for (int i = 0; i < FLOOR_NUM; i++) {
        printf("第%d层\n", i + 1);
        for (int j = 0; j < ROOM_NUM; j++) {
            printf("房间%d：", j + 1);
            for (int k = 0; k < rooms[i][j].cur_capacity; k++) {
                printf("%s ", rooms[i][j].students[k].id);
            }
            printf("\n");
        }
        printf("\n");
    }
}

int main() {
    srand(time(NULL)); // 初始化随机数种子

    int student_num = 200;
    StudentInfo students[student_num];
    for (int i = 0; i < student_num; i++) {
        sprintf(students[i].id, "S%03d", i + 1); // 自动生成学号
        sprintf(students[i].class, "C%03d", i % 10 + 1); // 自动生成班级
        sprintf(students[i].gender, "%s", i % 2 == 0 ? "男" : "女"); // 自动生成性别
    }

    RoomInfo rooms[FLOOR_NUM][ROOM_NUM];
    initRooms(rooms);
    assignRooms(rooms, students, student_num);
    printRooms(rooms);

    return 0;
}

这个程序会生成200个学生，随机分配宿舍并输出结果。每个房间最多容纳5人，如果房间已满则会重新随机选择房间。
