9.11.2.1 Special Characters

The presence of a ‘ ; ’ on a line indicates the start of a comment that extends to the end of the current line.

If a ‘ # ’ 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 Comments ) or a preprocessor control command (see Preprocessing ).

The ‘ ` ’ character can be used to separate statements on the same line.
