Nested comments in Visual C++?

问题

Is it possible to enable nested comments (/* /* */ */) in Visual C++?

I can't seem to find the switch, if there is one.

回答1:

Nested comments are not allowed in the C++ standard. Visual C++ supports this standard.

Sorry, no nested comments.

回答2:

I don't think it's possible using that style of quote. The first "*/" will always "close" the quote.

回答3:

I don't believe that is possible, but if you want to "comment out" a chunk of code which itself contains comments, you could always use the preprocessor,

#ifdef NOT_REQUIRED

/**
 * foo
 */
 void foo()
 { 

 }

#endif
