GetMessage : You can put in a human-readable message here although that's a fairly raw approach to sending along good error information.

getMessage：可以在这里放置易于理解的消息，但是这是一个传送良好错误信息的相当原始的方法。

For example, in Listing 3, it would be good to receive an error message when doing square-root (-22.0) and exiting the program with return status -1 instead of returning -1.0.

例如，在清单3中，当执行square - root(- 22.0)时应该产生错误消息，程序退出，返回状态应该是- 1而不是- 1.0。

That's true. Although you can always redirect stderr and stdout, nothing beats a good command line error message.

这是事实。虽然你总是可以重定向标准输出和标准错误输出，没有什么比命令行错误消息好。

So generally, if you don't get an error message in a command line environment like this, that's good.

一般来说，如果你在命令行界面，没有收到错误信息，那就是好消息。
