注意关闭方法只释放编写器需要的资源，并不关闭底层的输出。

Note that the close method only releases any resources that the writer acquired, but it does not close the underlying output.

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。
