如何用C预处理器编写while循环？ [英] How to write a while loop with the C preprocessor?

问题描述

我是从教育/黑客的角度提出这个问题的，（我真的不想这样编码）。

I am asking this question from an educational/hacking point of view, (I wouldn't really want to code like this).

是否有可能实现仅使用 C 预处理程序指令进行while循环。我知道宏不能递归扩展，那么如何实现呢？

Is it possible to implement a while loop only using C preprocessor directives. I understand that macros cannot be expanded recursively, so how would this be accomplished?

推荐答案

看看增强预处理器库，该库可让您在预处理器中编写循环，还有更多。

Take a look at the Boost preprocessor library, which allows you to write loops in the preprocessor, and much more.
