Then, what happens when we if the file did not have foobar, like there was a nonzero error code, then we print " this file doesn't have any foobar, we're going to add one" .

然后，如果文件没有 foobar，就像有一个非零错误代码，然后我们打印“此文件没有任何 foobar，我们将添加一个”，会发生什么。

Similarly, if we instead of use " false" , we use something like " true" , since true will have a zero error code, then the second one will be short-circuited and it won't be printed.

类似地，如果我们不使用“ false”，而是使用“ true”之类的东西，因为 true 将有一个零错误代码，那么第二个错误代码将被短路并且不会被打印。
