Question

代码很丑陋，应该构成一个简单的测试，但是存在一些问题。.重点是创建一个包含十个问题的问答游戏，其目的是选择并选择带有箭头的答案并输入。我希望提出一些建议或改进。

在单击“输入”按钮后，如何重新构造它以继续进行下一个问题。.到目前为止，只有一个问题可用，它检查是否正确，并将点+1添加到变量“ d”中。

#include <iostream>

using namespace std;
int main()
{   char k;
    int m = 0, d = 0 ;
    const int Up = 72;
    const int Down = 80;
    const int Enter = 13;
    cout<<" 1.Which is the closest planet to the Sun?\n"
        "> A) Mercury\n"
        "  B) Mars\n"
        "  C) Earth\n"
        "  D) Neptune\n";
    do {
        k = getch();
        if(k == Down) {
            m++;

        else if(k == Up) {
            m--;

定义代表问题（及其答案）的数据结构，并创建此类结构的集合。
然后，您可以遍历它们，也可以随意选择其中之一。

例如：

#include <iostream>
#include <string>
#include <vector>

struct Question
{
    std::string question;
    std::vector<std::string> answers;
    int correct;
};

std::vector<Question> questions = 
{
    { "What is the moon", {"Cheese", "Fake"}, 0 },
    { "Where's Waldo", {"Over here", "Over there"}, 1}
};

int main()
{
    for (const auto& q: questions)
    {
        std::cout << q.question << "?\n";
        char option = 'A';
        for (const auto& a: q.answers)
        {
            std::cout << option << ") " << a << '\n';
            option += 1;
        }
        std::cout << "Correct answer: " << q.answers[q.correct] << "\n\n";
    }
}

输出：

What is the moon?
A) Cheese
B) Fake
Correct answer: Cheese

Where's Waldo?
A) Over here
B) Over there
Correct answer: Over there
