如何使用 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/黑客的角度来问这个问题的(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).

是否可以仅使用 C 预处理器指令来实现 while 循环.我知道宏不能递归扩展，那么如何实现?

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

查看Boost 预处理器 库，它允许您在预处理器中编写循环等等.

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