2.13 Operators and punctuators [lex.operators]

1

The lexical representation of C++ programs includes a number of preprocessing tokens which are used in the syntax of the preprocessor or are converted into tokens for operators and punctuators:

preprocessing-op-or-punc: one of
	{ 	} 	[ 	] 	# 	## 	( 	)
	<: 	:> 	<% 	%> 	%: 	%:%: 	; 	: 	...
	new 	delete 	? 	:: 	. 	.*
	+ 	- 	* 	/ 	% 	^ 	& 	| 	~
	! 	= 	< 	> 	+= 	-= 	*= 	/= 	%=
	^= 	&= 	|= 	<< 	>> 	>>= 	<<= 	== 	!=
	<= 	>= 	&& 	|| 	++ 	-- 	, 	->* 	->
	and 	and_eq 	bitand 	bitor 	compl 	not 	not_eq
	or 	or_eq 	xor 	xor_eq

Each preprocessing-op-or-punc is converted to a single token in translation phase 7 ([lex.phases]).
