停车场管理系统c语言代码

以下是一个简单的停车场管理系统的 C 语言代码示例：

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

#define MAX_SIZE 100

typedef struct {
    int id;
    char license_number[10];
} Car;

int main() {
    Car parking_lot[MAX_SIZE];
    int car_count = 0;

    while (1) {
        printf("Enter 1 to park a car, 2 to remove a car, 3 to view parking lot, 4 to exit: ");
        int choice;
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                if (car_count >= MAX_SIZE) {
                    printf("Parking lot is full!\n");
                    break;
                }

                printf("Enter license number of car to park: ");
                char license_number[10];
                scanf("%s", license_number);

                Car new_car;
                new_car.id = car_count + 1;
                strcpy(new_car.license_number, license_number);
                parking_lot[car_count++] = new_car;

                printf("Car parked successfully. Car ID: %d\n", new_car.id);
                break;

            case 2:
                printf("Enter ID of car to remove: ");
                int remove_id;
                scanf("%d", &remove_id);

                int found_car = 0;
                for (int i = 0; i < car_count; i++) {
                    if (parking_lot[i].id == remove_id) {
                        found_car = 1;
                        printf("Car with license number %s removed from parking lot.\n", parking_lot[i].license_number);

                        for (int j = i; j < car_count - 1; j++) {
                            parking_lot[j] = parking_lot[j + 1];
                        }

                        car_count--;
                        break;
                    }
                }

                if (!found_car) {
                    printf("Car with ID %d not found in parking lot!\n", remove_id);
                }

                break;

            case 3:
                printf("Current parking lot status:\n");
                for (int i = 0; i < car_count; i++) {
                    printf("Car ID: %d, License Number: %s\n", parking_lot[i].id, parking_lot[i].license_number);
                }
                break;

            case 4:
                printf("Exiting program...\n");
                exit(0);

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

    return 0;
}

该代码使用一个 `Car` 结构体来表示停在停车场中的汽车。`parking_lot` 数组用于存储所有的汽车，`car_count` 变量用于记录停车场中当前汽车的数量。

程序提供了四个选项：

1. 停车：输入车牌号，将新车辆添加到停车场中。
2. 取车：根据车辆 ID 将车辆从停车场中移除。
3. 查看停车场状态：打印当前所有停在停车场中的车辆。
4. 退出程序。

请注意，该代码仅用于演示目的，并不完整或最优。实际使用中需要根据具体需求进行更改和扩展。
