Can you give me examples of odd single line comments in C++?

Answer 1

I think you are missing the /* comment */ case.

Answer 2

The fun ones are formed by trigraphs and line continuations. My personal favorite is:

/??/
* this is a comment *??/
/

Answer 3

You don't seem to handle escaped quotes, like:

"Comment\"//also inside string"

versus

"Comment"//not inside string"

Answer 4

I think you can't handle

  puts("Test \
    // not a comment");

and this is also likely to make problems:

  puts("'"); // this is a comment

Answer 5

// Single line comments can\
actually be multi line.

Answer 6

The handling of \ character at the end of the line is performed at the earlier translation phase (phase 2) than replacement of comments (phase 3). For this reason, a // comment can actually occupy more than one line in the original source file

// This \
whole thing \
is actually \
a single comment

P.S. Oh... I see this is already posted. OK, I'll keep it alive just for mentioning phases of translation :)

Answer 7

This is always a favourite:

// Why doesn't this run?????????????????????/
foo(bar);
