如何产生的CPP宏换行？ [英] How to generate a newline in a cpp macro?

问题描述

我怎样写一段cpp的宏观其扩展到包括换行符？

How do I write a cpp macro which expands to include newlines?

推荐答案

C＆放大器; C ++编译器忽略未加引号的空格（除>>模板的问题），因此让宏发出新行并没有真正意义。您可以结束与反斜杠宏观的每一行作出宏跨越几行，但不输出换行。

C & C++ compilers ignore unquoted whitespace (except for the > > template issue), so getting a macro to emit newlines doesn't really make sense. You can make a macro span several lines by ending each line of the macro with a backslash, but this doesn't output newlines.
