C# 在構建多項選擇測驗時，我們如何計算正確/錯誤答案並根據計數形成分數？

Question

所以我將有 4 個問題，每個問題值 25 分，滿分是 100。我不確定如何根據我的代碼和表格分數代碼來計算答案。 謝謝你幫我。 （我提出了 1 個問題來縮短代碼，但在我的 VS 中有 4 個問題）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MCQuiz
{
    class Program
    {
        static void Main(string[] args)
        {


            string answer;

            Console.WriteLine("Q1-Every Statement in C# language must terminate with: ");
            Console.WriteLine(" \t a.  ; ");
            Console.WriteLine(" \t b.  , ");
            Console.WriteLine(" \t c. . ");
            Console.WriteLine(" \t d.  ? ");
            Console.WriteLine();


            Console.Write("Enter the letter (a, b, c, d) for correct Answer: ")

            answer = Console.ReadLine();

            if (answer == "a")
            {
                Console.WriteLine("Your Answer '{0}' is Correct.", answer);
            }
            else
            {
                Console.WriteLine("Your Answer '{0}' is Wrong.", answer);
            }
            Console.WriteLine();
            Console.WriteLine("****************************************");
           
        }
    }
}

您可以在 integer 變量中跟蹤 totalScore，並使用+=運算符將每個正確答案加 25，這是以下示例中totalScore = totalScore + 25的簡寫。

class Program
{
    static void Main(string[] args)
    {
        int totalScore = 0;   // initiate variable
        string answer;

        Console.WriteLine("Q1-Every Statement in C# language must terminate with: ");
        Console.WriteLine(" \t a.  ; ");
        Console.WriteLine(" \t b.  , ");
        Console.WriteLine(" \t c. . ");
        Console.WriteLine(" \t d.  ? ");
        Console.WriteLine();


        Console.Write("Enter the letter (a, b, c, d) for correct Answer: ")

        answer = Console.ReadLine();

        if (answer == "a")
        {
            totalScore += 25;   // add score
            Console.WriteLine("Your Answer '{0}' is Correct.", answer);
        }
        else
        {
            Console.WriteLine("Your Answer '{0}' is Wrong.", answer);
        }
        Console.WriteLine();
        Console.WriteLine("****************************************");
        Console.WriteLine($"You scored {totalScore} points"); // output result
    }
}
