机房预定系统c语言代码

以下是一个简单的机房预定系统的C语言代码示例，仅供参考：

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

#define MAX_ROOMS 10
#define MAX_NAME_LEN 50

typedef struct {
    int room_no;
    char name[MAX_NAME_LEN];
    int reserved;
} Room;

void print_menu() {
    printf("\n");
    printf("1. Reserve a room\n");
    printf("2. Cancel a reservation\n");
    printf("3. List all rooms\n");
    printf("4. Quit\n");
    printf("Enter your choice: ");
}

int get_choice() {
    int choice;
    scanf("%d", &choice);
    return choice;
}

int reserve_room(Room *rooms, int room_no, char *name) {
    if (rooms[room_no - 1].reserved == 0) {
        rooms[room_no - 1].reserved = 1;
        rooms[room_no - 1].room_no = room_no;
        strcpy(rooms[room_no - 1].name, name);
        return 1;
    } else {
        return 0;
    }
}

int cancel_reservation(Room *rooms, int room_no) {
    if (rooms[room_no - 1].reserved == 1) {
        rooms[room_no - 1].reserved = 0;
        strcpy(rooms[room_no - 1].name, "");
        return 1;
    } else {
        return 0;
    }
}

void list_rooms(Room *rooms) {
    printf("\n");
    printf("Room No.    Name        Reserved\n");
    printf("=================================\n");
    for (int i = 0; i < MAX_ROOMS; i++) {
        printf("%-12d%-12s", rooms[i].room_no, rooms[i].name);
        if (rooms[i].reserved == 1) {
            printf("Yes\n");
        } else {
            printf("No\n");
        }
    }
}

int main() {
    Room rooms[MAX_ROOMS];
    for (int i = 0; i < MAX_ROOMS; i++) {
        rooms[i].room_no = i + 1;
        rooms[i].reserved = 0;
        strcpy(rooms[i].name, "");
    }

    printf("Welcome to the room reservation system!\n");
    while (1) {
        print_menu();
        int choice = get_choice();
        switch (choice) {
            case 1:
                printf("\nEnter the room number (1-10): ");
                int room_no;
                scanf("%d", &room_no);
                printf("Enter your name: ");
                char name[MAX_NAME_LEN];
                scanf("%s", name);
                if (reserve_room(rooms, room_no, name) == 1) {
                    printf("Room %d reserved for %s.\n", room_no, name);
                } else {
                    printf("Sorry, room %d is already reserved.\n", room_no);
                }
                break;
            case 2:
                printf("\nEnter the room number to cancel the reservation (1-10): ");
                int cancel_room_no;
                scanf("%d", &cancel_room_no);
                if (cancel_reservation(rooms, cancel_room_no) == 1) {
                    printf("Reservation for room %d cancelled.\n", cancel_room_no);
                } else {
                    printf("Sorry, room %d is not reserved.\n", cancel_room_no);
                }
                break;
            case 3:
                list_rooms(rooms);
                break;
            case 4:
                printf("Goodbye!\n");
                exit(0);
            default:
                printf("Invalid choice, please try again.\n");
                break;
        }
    }
    return 0;
}

该代码使用了一个包含10个房间的结构体数组来表示机房，每个房间包含房间号、预定情况和预定人姓名等信息。主函数中包含一个菜单循环，根据用户的选择执行相应的操作，如预定房间、取消预定和列出所有房间等。
