If the first one didn't have a zero error code, it's gonna try to do the second one.

如果第一个没有零错误代码，它将尝试执行第二个。

Citing earlier research by Dr Dror, the report's authors stated, for example, that fingerprint examiners' claims of zero error rates were scientifically implausible.

引用这篇报道的作者Dror博士早前做的研究，例如，指纹鉴定者宣称的零误差在科学上是不合理的。

But since we have a zero error code, something happened - just that everything went correct and everything is fine.

但由于我们有一个零错误代码，所以发生了一些事情 - 只是一切都正确并且一切都很好。

There are some interesting commands like " true" , for example, will always have a zero error code, and false will always have a one error code.

有一些有趣的命令，例如“true”，将始终具有零错误代码，而 false 将始终具有一错误代码。

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。
