宿舍管理系统c语言

宿舍管理系统是一个比较复杂的系统，需要设计多个模块，包括学生信息管理、宿舍楼信息管理、宿舍房间信息管理、宿舍住宿情况管理、宿舍卫生情况管理等等。

在C语言中，可以使用结构体来定义学生信息、宿舍楼信息、宿舍房间信息等数据类型，同时也需要使用文件读写来进行数据的持久化存储。下面是一个简单宿舍管理系统的代码示例，供参考：

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

#define MAX_STUDENT_NUM 1000
#define MAX_BUILDING_NUM 20
#define MAX_ROOM_NUM 100

// 学生信息结构体
typedef struct {
    char name[20];  // 姓名
    char sex;       // 性别：M-男，F-女
    char id[20];    // 学号
    int building;   // 所在宿舍楼
    int room;       // 所在宿舍房间
} Student;

// 宿舍楼信息结构体
typedef struct {
    int id;             // 宿舍楼编号
    char name[20];      // 宿舍楼名称
    int floor_num;      // 层数
    int room_num_per_floor;  // 每层房间数
} Building;

// 宿舍房间信息结构体
typedef struct {
    int building;   // 所在宿舍楼
    int room;       // 房间号
    char type[10];  // 房间类型：single-单人间，double-双人间
    int capacity;   // 房间容纳人数
} Room;

// 全局变量
Student students[MAX_STUDENT_NUM];          // 学生信息数组
Building buildings[MAX_BUILDING_NUM];       // 宿舍楼信息数组
Room rooms[MAX_BUILDING_NUM][MAX_ROOM_NUM]; // 宿舍房间信息数组

int student_num = 0;        // 学生总数
int building_num = 0;       // 宿舍楼总数
int room_num[MAX_BUILDING_NUM] = {0};     // 每个宿舍楼的房间总数

// 读取学生信息
void read_students() {
    FILE *fp = fopen("students.txt", "r");
    if (fp == NULL) {
