单链表实现宾馆客房管理系统的各类客房收入情况的源代码

以下是单链表实现宾馆客房管理系统的各类客房收入情况的源代码：

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

// 定义客房结构体
typedef struct Room {
    int id; // 客房编号
    char type[20]; // 客房类型
    int price; // 客房价格
    int income; // 客房收入
    struct Room* next; // 指向下一个客房的指针
} Room;

// 定义单链表结构体
typedef struct List {
    Room* head; // 指向链表头结点的指针
    int len; // 链表长度
} List;

// 初始化单链表
List* initList() {
    List* list = (List*)malloc(sizeof(List));
    list->head = NULL;
    list->len = 0;
    return list;
}

// 创建新客房
Room* createRoom(int id, char* type, int price) {
    Room* room = (Room*)malloc(sizeof(Room));
    room->id = id;
    strcpy(room->type, type);
    room->price = price;
    room->income = 0;
    room->next = NULL;
    return room;
}

// 在单链表尾部添加新客房
void addRoom(List* list, Room* room) {
    if (list == NULL || room == NULL) {
        return;
    }

    Room* p = list->head;
    if (p == NULL) {
        list->head = room;
    } else {
        while (p->next != NULL) {
            p = p->next;
        }
        p->next = room;
    }
    list->len++;
}

// 根据客房编号查找客房
Room* findRoomById(List* list, int id) {
    if (list == NULL) {
        return NULL;
    }

    Room* p = list->head;
    while (p != NULL) {
        if (p->id == id) {
            return p;
        }
        p = p->next;
    }

    return NULL;
}

// 更新客房收入
void updateRoomIncome(List* list, int id, int income) {
    Room* room = findRoomById(list, id);
    if (room != NULL) {
        room->income += income;
    }
}

// 输出所有客房信息
void printRooms(List* list) {
    printf("客房编号\t客房类型\t客房价格\t客房收入\n");
    Room* p = list->head;
    while (p != NULL) {
        printf("%d\t\t%s\t\t%d\t\t%d\n", p->id, p->type, p->price, p->income);
        p = p->next;
    }
}

int main() {
    List* list = initList();

    // 添加客房
    addRoom(list, createRoom(101, "单人间", 150));
    addRoom(list, createRoom(102, "双人间", 200));
    addRoom(list, createRoom(103, "豪华套房", 500));

    // 更新客房收入
    updateRoomIncome(list, 101, 300);
    updateRoomIncome(list, 102, 600);
    updateRoomIncome(list, 103, 1000);

    // 输出客房信息
    printRooms(list);

    return 0;
}

上述代码实现了一个简单的宾馆客房管理系统，可以在单链表中存储客房信息，并且能够根据客房编号进行查询和更新客房收入。
