工作学习 / 专业技术讨论 / c的一个面试问题，How do you write a program which produces its own source code as its output? 我不会，所以请教那位高手给个例子.谢谢先.

if you could write it, you can win Turing Award. Also, there is something named Google.

因为是c语言，源码和执行码是分离的，所以我写了一个小程序，叫test.c，编译成test，执行，输出的代码再写入test.c.（test执行的过程很简单，就是读test.c,写入另一个文件tmp.c，然后move tmp.c到test.c就完了）。我的疑问是：这个问题是否有更深层的意思？

恭喜你,你错了这道题目.其实很简单,考的是一个预定义的宏,这题目出得差,估计EMPLOYER是一个不怎么懂技术的公司.

1.use complete path name at compiling time. 2. run software at local node. 3. use __FILE__ to get the file at running time.
