用Ubuntu编写一个C语言程序设计的酒店管理系统源代码

好的，以下是一个使用Ubuntu操作系统编写的C语言程序的示例，用于管理一家酒店：

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

#define MAX_ROOMS 100
#define MAX_NAME 50

typedef struct {
    int room_number;
    char guest_name[MAX_NAME];
    int num_of_nights;
    float rate;
} Room;

int main()
{
    Room rooms[MAX_ROOMS];
    int num_rooms = 0;
    int choice;
    int i;

    while (1) {
        printf("\n\nHotel Management System\n");
        printf("-----------------------\n");
        printf("1. Add Room\n");
        printf("2. Remove Room\n");
        printf("3. View Rooms\n");
        printf("4. Exit\n");
        printf("\nEnter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                if (num_rooms == MAX_ROOMS) {
                    printf("Error: Maximum number of rooms reached.\n");
                    break;
                }
                printf("\nEnter room number: ");
                scanf("%d", &rooms[num_rooms].room_number);
                printf("Enter guest name: ");
                scanf("%s", rooms[num_rooms].guest_name);
                printf("Enter number of nights: ");
                scanf("%d", &rooms[num_rooms].num_of_nights);
                printf("Enter rate per night: ");
                scanf("%f", &rooms[num_rooms].rate);
                num_rooms++;
                printf("\nRoom added successfully.\n");
                break;

            case 2:
                if (num_rooms == 0) {
                    printf("Error: No rooms to remove.\n");
                    break;
                }
                printf("\nEnter room number to remove: ");
                int room_number;
                scanf("%d", &room_number);
                for (i = 0; i < num_rooms; i++) {
                    if (rooms[i].room_number == room_number) {
                        num_rooms--;
                        rooms[i] = rooms[num_rooms];
                        printf("\nRoom removed successfully.\n");
                        break;
                    }
                }
                if (i == num_rooms) {
                    printf("\nError: Room not found.\n");
                }
                break;

            case 3:
                if (num_rooms == 0) {
                    printf("\nNo rooms found.\n");
                    break;
                }
                printf("\nRoom Number\tGuest Name\tNumber of Nights\tRate per Night\n");
                printf("----------------------------------------------------------------\n");
                for (i = 0; i < num_rooms; i++) {
                    printf("%d\t\t%s\t\t%d\t\t%.2f\n", rooms[i].room_number, rooms[i].guest_name, rooms[i].num_of_nights, rooms[i].rate);
                }
                break;

            case 4:
                printf("\nGoodbye!\n");
                exit(0);

            default:
                printf("\nError: Invalid choice.\n");
                break;
        }
    }

    return 0;
}

这个程序使用结构体来存储每个房间的信息，包括房间号、客人姓名、入住天数和每晚的费率。程序提供了以下操作：

1. 添加房间
2. 删除房间
3. 查看房间
4. 退出程序

你可以根据你的需求对程序进行修改和扩展。
