如何重載此代碼以使其接受我的輸入？

Question

我正在開發一個程序來收集“瓶驅動器”的結果。 該程序將提示用戶輸入1到4之間的房間號，然后提示用戶輸入每個房間收集的瓶子數。 用戶應該可以選擇鍵入“退出”以顯示每個房間和收集的瓶子數量。

這是我現在的代碼，我很難擴展程序以支持多個房間。

namespace BottleDrive
{
  class Program
  {
    static void Main(string[] args)
    {
        int roomNumber;
        int numberOfBottles;
        char quit;

        Console.WriteLine("Enter the Room number you are in.");
        string roomSelect = "";
        roomSelect = Console.ReadLine();
        roomSelect = int.Parse(roomSelect);
        if (roomSelect >= 1)
        {
            Console.WriteLine("Enter the number of bottles collected by room one");
            string room1Bottles = "0";
            room1Bottles = Console.ReadLine();
            int room1 = int.Parse(room1Bottles);
            if (room1 == 1)
            {
                room1Bottles += room1;
                Console.WriteLine("Room one has " + room1 + " many bottles collected");
            }
        }
        if (Console.ReadLine() = quit)
        {
            Console.WriteLine("Room one has collected:" + room1Bottles + "\nRoom two has collected:" + room2Bottles + "Press space to quit");
            string systemExit = "";
            if (Console.ReadLine = "")
            {
                systemExit(0);
            }
        }

Answer 1

您可以利用一個數組（房間號將用於計算索引）來跟蹤收集的瓶子數量：

int[] bottles = new int[4];

while (true)
{
    Console.Write("Enter the room you're in: ");
    string inputString = Console.ReadLine();
    if (inputString == "quit")
        break;
    int room = int.Parse(inputString);

    Console.Write("Bottles collected in room {0}: ", room);
    bottles[room - 1] = int.Parse(Console.ReadLine());
}

for (int i = 0; i < bottles.Length; ++i)
    Console.WriteLine("Bottles collected in room {0} = {1}", i + 1, bottles[i]);

然后，一旦用戶鍵入“退出”以顯示收集了多少瓶，您就可以再次遍歷數組。

Answer 2

我懷疑您的代碼僅是因為以下原因而編譯：

string roomSelect = "";
roomSelect = Console.ReadLine();
roomSelect = int.Parse(roomSelect);

使用整數變量存儲已解析的房間號。

Answer 3

因為您只需要知道每個房間一個變量，所以可以使用整數數組，在這種情況下，該數組包含4個條目。 您將從用戶那里獲取輸入並將其轉換為int。 然后，您可以使用該數字訪問正確的數組索引。

  int[] arr_rooms = new int[4];
 Console.WriteLine("Enter room number");
 int number = Int.Parse(Console.ReadLine());
 Console.WriteLine("enter number of bottles");
 int bottles = Int.Parse(Console.ReadLine());

 arr_rooms[number - 1] = bottles; //the -1 is because arrays start at 0

 Console.WriteLine("bottles in room 1 is " + arr_rooms[0].toString());

Answer 4

您將必須聲明一個數組來存儲瓶數：

static void Main(string[] args)
{
    const int NumberOfRooms = 4;

    int[] numberOfBottles = new int[NumberOfRooms];

    while (true) {
        Console.WriteLine("Enter the Room number you are in or 'q' and <enter> to quit.");
        string line = Console.ReadLine();
        if (line.ToLower().StartsWith("q")) {
            break;
        }
        int roomNumber = int.Parse(line) - 1;
        if (roomNumber >= 0 && roomNumber < NumberOfRooms) {
            Console.WriteLine("Enter the number of bottles collected by room number " + (roomNumber + 1));
            line = Console.ReadLine();
            int bottles = int.Parse(line);
            numberOfBottles[roomNumber] += bottles;
            Console.WriteLine("{0} bottles collected for room number {1}", numberOfBottles[roomNumber], roomNumber + 1);
            Console.WriteLine();
        }
    }
    Console.WriteLine();
    for (int i = 0; i < NumberOfRooms; i++) {
        Console.WriteLine("{0} bottles collected for room number {1}", numberOfBottles[i], i + 1);
    }
    Console.WriteLine("Press any key to quit.");
    Console.ReadKey();
}

還要注意，數組的索引從0到項數減一。
