Question

我必须创建一个以随机顺序打印问题的测验。我已经在if语句中写出了所有问题，如果已经回答了10个问题，我希望显示所有问题，并给出正确的答案和用户输入的答案进行比较。我还不知道怎么做，所以代码在1完成后转到下一个if语句。

如果声明（问题）和随机数生成器指向另一个if if等，我如何完成1。

static void Main(string[] args)
    {
        string answer1;
        string answer2;
        string answer3;
        string answer4;
        string answer5;
        string answer6;
        string answer7;
        string answer8;
        string answer9;
        string answer10;
        int answeredQs = 0;

        Random rnd = new Random();
        int questionNum = rnd.Next(1,10);
        Console.WriteLine("Question Number: " + questionNum);

            if (questionNum == 1)
            {
                Console.WriteLine("What is a CPU?");
                answer1 = Console.ReadLine();
                answeredQs = +1;
            }

            if (questionNum == 2)
            {
                Console.WriteLine("What does 'RAM' stand for?");
                answer2 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 3)
            {
                Console.WriteLine("What is RAM?");
                answer3 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 4)
            {
                Console.WriteLine("How do you measure how fast a processor is?");
                answer4 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 5)
            {
                Console.WriteLine("What is an ALU & what does it do?");
                answer5 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 6)
            {
                Console.WriteLine("What is a register?");
                answer6 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 7)
            {
                Console.WriteLine("What is EEPROM?");
                answer7 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 8)
            {
                Console.WriteLine("What is the difference between SRAM and DRAM?");
                answer8 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 9)
            {
                Console.WriteLine("What is ROM?");
                answer9 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (questionNum == 10)
            {
                Console.WriteLine("What does the Control Unit do?");
                answer10 = Console.ReadLine();
                answeredQs = answeredQs + 1;
            }

            if (answeredQs == 10)
            {
                Console.WriteLine("asdasdasd");
            }

Answer 1

您可以将if语句放在循环中（for，while ...）

此外，例如，通过将问题放在ArrayList中（或任何其他“数据存储”结构，例如简单数组），您的代码可以更具可读性。

然后，您可以使用此结构中的问题的索引，始终处于循环中。

希望这有帮助
