5.12 Operators and punctuators [lex.operators]

#
The lexical representation of C++ programs includes a number of preprocessing tokens that are used in the syntax of the preprocessor or are converted into tokens for operators and punctuators:
preprocessing-op-or-punc:
	preprocessing-operator
	operator-or-punctuator

preprocessing-operator: one of
	#        ##       %:       %:%:

operator-or-punctuator: one of
	{        }        [        ]        (        )
	<:       :>       <%       %>       ;        :        ...
	?        ::       .        .*       ->       ->*      ~
	!        +        -        *        /        %        ^        &        |
	=        +=       -=       *=       /=       %=       ^=       &=       |=
	==       !=       <        >        <=       >=       <=>      &&       ||
	<<       >>       <<=      >>=      ++       --       ,
	and      or       xor      not      bitand   bitor    compl
	and_eq   or_eq    xor_eq   not_eq
Each operator-or-punctuator is converted to a single token in translation phase 7.
