|

|
|
|
||
|
|
<p>If a ‘<samp><span class="samp">#</span></samp>’ appears as the first character of a line then the whole
|
||
|
|
line is treated as a comment, but in this case the line could also be
|
||
|
|
a logical line number directive (see <a href="Comments.html#Comments">Comments</a>) or a preprocessor
|
||
|
|
control command (see <a href="Preprocessing.html#Preprocessing">Preprocessing</a>).

|

|
|
and as a symbol denoting the current location counter.

|

is one character in between, it is a character constant, otherwise it is

a string constant.
