And I'll sit there staring at the output, staring at the code, not realizing that that output was not produced by that code.

然后我就坐在那儿盯着输出的结果，看着代码，没有意识到输出的结果,并不是由我的代码产生。

我传一个X，之后我把返回值赋值给,很明显，这一行代码,将会产生什么作用？

So you have to somehow convert the source code, the C code into 0s and 1s and for that process there exist this tool called a compiler that someone else wrote that takes this stuff as input and produces this stuff as output.

所以你必须把源代码，即C语言代码转换成二进制文件,这个过程就需要我们提到的编译器了,它是由别人编写的一个软件，以这些代码作为输入,将会产生的输出。

So in other words, if you terminate these lines early, if you terminate the four loop early, if you terminate an if condition early with that semicolon, the code may very well work; and this is a common source -- of frustration and conundrum because you don't -- because your code looks right and yet it's misbehaving, but that semicolon means stop looking for subsequent lines of related code.

换句话说，如果你用分号过早的终止了这些代码行，如果你过早地终止了那个for循环，如果如此,一个if条件，代码可能可以运行，这就是,挫折和问题产生的源头，因为你没有-,因为你的代码看起来是正确的，但是运行是错误的，那个分号的意思是,停止寻找后面相关的代码。
