关于代码的几个问题 [英] Several Questions About Code

问题描述

string keystroke(char KeyStroke, string output2){

    while (true==true) {
        KeyStroke = getch();
        if (KeyStroke == 0)
        {
            KeyStroke = getch(); // Even though there are 2 getch() it reads one keystroke
            switch (KeyStroke)
            {
            case UP_ARROW:
                Keystroke1 = "up";
                charpos_calculation(Keystroke1);
            break;
            }
        }
    }
    return output2;
}

问题1 - 跑步时我的程序返回此错误。此项目的POSIX名称已弃用

我需要做些什么来解决此问题。



问题2 - 我如何获得击键？我通过#define UP_ARROW 25来定义向上箭头。这是正确的方式和正确的价值。



我想弄清楚的是如何直接来自用户的键盘输入。我该如何操作，这样用户就不必按回车。



这是一个使用Windows Visual Studio 2012 Express的控制台应用程序。



这也是我的大型游戏代码的一部分。

Question 1 - When ran my program returns this error .The POSIX name for this item is deprecated
What do I need to do to fix this.

Question 2 - How do I get a keystroke? I defined the up arrow by #define UP_ARROW 25. Is this the right way and the right value.

What I'm trying to figure out is how to get direct keyboard input from the user. How would I do this so the user doesn't have to press enter.

This is a console application using Windows Visual Studio 2012 Express.

Also this is part of my code of a larger game.

我认为这是一个警告，而不是错误。无论如何编译器是对的，当然:-)，请参阅文档 [ ^ ]用于修复（即使用 _getch [< a href =http://msdn.microsoft.com/en-us/library/078sfkak(v=vs.110).aspx\"target =_ blanktitle =New Window> ^ ] ）。

I believe that is a warning, not an error. Anyway the compiler is right, of course :-), see the documentation[^] for a fix (that is use _getch[^] instead).

你可以测试它。
