c语言实现宾馆客房管理

在 C 语言中实现宾馆客房管理系统通常会涉及结构体、数组、文件操作以及函数的使用。下面是一个简单的示例，描述了如何设计这个系统的基本框架：

1. 定义客房结构体 (Room)：

typedef struct {
    int room_number;
    char guest_name[50];
    bool is_booked;
} Room;

2. 动态创建客房数组 (HotelRooms) 和分配内存：

Room *HotelRooms = NULL;
int num_of_rooms;

3. 宾馆房间操作函数：
- 预订房间：

void book_room(Room **rooms, int room_number) {
    // 检查房间是否可用
    if (!(*rooms)[room_number - 1].is_booked) {
        (*rooms)[room_number - 1].is_booked = true;
        printf("Room %d booked by %s.\n", room_number, (*rooms)[room_number - 1].guest_name);
    } else {
        printf("Room %d already booked.\n", room_number);
    }
}

- 解除预订：

void cancel_reservation(Room **rooms, int room_number) {
    if ((*rooms)[room_number - 1].is_booked) {
        (*rooms)[room_number - 1].is_booked = false;
        printf("Room %d reservation canceled.\n", room_number);
    } else {
        printf("No reservation found for Room %d.\n", room_number);
    }
}

4. 文件操作，如读取/保存房间信息：

void save_rooms_to_file(Room *rooms, int num_of_rooms) {
    FILE* file = fopen("hotel_rooms.txt", "w");
    for (int i = 0; i < num_of_rooms; i++) {
        fprintf(file, "%d - %s - %s\n", rooms[i].room_number, rooms[i].guest_name, rooms[i].is_booked ? "Booked" : "Available");
    }
    fclose(file);
}

void load_rooms_from_file(Room **rooms, int *num_of_rooms) {
    FILE* file = fopen("hotel_rooms.txt", "r");
    while (fgetsRooms从file中读取数据并更新结构体数组...
    fclose(file);
}
