C＆＃x2B;＆＃x2B;控制台应用程序复选框

Question

我正在Visual Studio C ++中编写控制台应用程序，并想像此C＃ application 。

是否有C ++的类似解决方案？

Answer 1

我设法通过Alex f注释的_KBHIT函数创建了一个最小的解决方案。

每次制作一些货币时，我只是打印出控制台。就在打印之前，我要清理控制台。使用_khbit，我正在检查用户是否按下正确的键盘输入之一。如果是否检查了复选框，我将保存在矢量中。 （仅在Windows！）

使用它，只需提供一个字符串的向量，它将返回int的向量，其中0（未检查）或1（检查）。

#include "stdafx.h"
#include "checkbox.h"
#include <string> 
int main()
{
    std::vector<string> lineTexts;
    lineTexts.push_back("first line");
    lineTexts.push_back("second line");
    lineTexts.push_back("third line");
    string headline = "Choose one of the following";

    Checkbox checkbox(headline, lineTexts);
    std::vector<int> result = checkbox.run();

    cout << "Checkboxes: " << endl;
    for (size_t i = 0; i < result.size(); i++)
    {
        cout << "line " << i << " " << result[i] << endl;
    }
}
