重载三元？：运算符，或更改为包含文件中的{} else {} [英] Overload ternary ?: operator, or change to if{}else{} in included files

问题描述

这里的研究项目。在我的C ++库中，我包含C文件：

Research project here. In my C++ library, I am including C files:

#include "aprogram.c"

我通过重载（几乎）所有运算符来执行符号。

which I execute symbolically by overloading (almost) all operators.

我有能够检测（条件）？这个：那个并提取条件，这个和那个用于我的符号执行库。但是， SO 1 ，< a href =https://stackoverflow.com/questions/2874589/unoverloadable-c-operators/2874641#2874641> SO 2 和 SO 3 等已经帮助我意识到？：不能超载。

I have to be able to detect (condition) ? this : that and extract condition, this and that for usage in my symbolic execution library. However, SO 1, SO 2 and SO 3 amongst others already helped me realise that ?: cannot be overloaded.

• 我有什么方法强行超载？：无论如何？


• 我可以将包含的C文件中的所有？：语句更改为ifelse语句而不实际更改文件吗？

• Is there any way for me to forcibly overload ?: anyways?
• Can I change all ?: statements in my included C file into ifelse-statements without actually changing the file?

推荐答案

根据C ++标准，你不允许重载？：
你能做的最好就是使用C宏（但这可能导致可怕的代码）。

According to the C++ standard you are not permitted to overload ?: The best you can do is use C macros (but this can lead to horrible code).
