C 编程 - 多行注释

Question

如何忽略另一个多行注释里面的多行注释符号？

假设我想将整个代码放在注释中，以便我可以测试代码中的其他内容

/* This is my first comment */
printf("\n This is my first print command");

/* This is my second comment */
printf("\n This is my second print command");

如果我这样做

/* 

/* This is my first comment */
printf("\n This is my first print command");

/* This is my second comment */
printf("\n This is my second print command");

*/

这是在制造错误。

您期望的是嵌套的多行注释。

直接引用标准C11，章节§6.4.9，

Except within a character constant, a string literal, or a comment, the characters /* introduce a comment. The contents of such a comment are examined only to identify multibyte characters and to find the characters */ that terminate it. ⁸³⁾

和脚注，

83 ) Thus, /* ... */ comments do not nest.

作为解决方法，您可以使用条件编译 block 作为

#if 0
.
.
.
.
#endif 

将整个 block 注释掉。
