To have the method split the lines based on a newline character, you have to explicitly specify the newline character.

我们不必添加一个新行字符，如果这样做了，测试就会失败。

We have not added a newline character; if we did, the test would fail.

Well it's a stupid looking program, but because I had more new line characters, and because I was using percent C, for individual characters, one per line, now I'm seeing dot slash ARG V2, well, now if I go ahead and rerun this with foo, I get this effect as well.

这是一个看起来很笨的程序，但是因为我有更多的新行代码，因为我使用的是%c，为单个字符使用的，每一行一个，现在我看到的是，/argv2，好的，现在如果我继续用foo返回它，我产生了这样的效果。
