命令行参数 [英] command line argument

问题描述

如何允许用户通过选择命令行参数输入输入或在C ++中提示输入？

Hi, how do you allow the user to enter the input through his choice of command line arguments or being prompted for input in C++?

推荐答案

参见，实例：如何解析命令行参数 [ ^ ]和基本输入/输出 [ ^ ] at at c ++ app中的 cplusplus.com 。

See, for instance: "How to parse command line parameters"[^] and "Basic Input/Output"[^] at cplusplus.com.

你有一个main函数，它有一个argc参数，命令行来自in。解析它是很常见的。

in a c++ app you have the main-function which has the argc parameter in which the the command line comes in. it is common use to parse it.
