Question

我试图编写程序来清除屏幕并显示一个简单的帮助＆＃39;用户要求的部分。然后该程序应该等待用户在再次清除屏幕之前按Enter键并重定向回到屏幕＆＃39;他们以前（在不同的功能）。但是，由于某些原因，程序在继续之前不等待用户输入，并且帮助屏幕根本不显示。也许一组不同的眼睛可以看到我失踪的东西？

据我所知，cin.get();函数应该可以暂停我的程序，但它并没有做它应该做的事情。我希望问题实际上在帮助部分，但我不知道它是如何搞砸的。任何帮助将不胜感激，谢谢。

Answer 1

在cin.ignore()之前添加cin.get()以摆脱输入缓冲区中的先前值。

为什么我的程序停止在我告诉它的地方？
