[lex.token] (original) (raw)

1

#

There are five kinds of tokens: identifiers, keywords, literals,13operators, and other separators.

Blanks, horizontal and vertical tabs, newlines, formfeeds, and comments (collectively, “white space”), as described below, are ignored except as they serve to separate tokens.

[ Note

:

Some white space is required to separate otherwise adjacent identifiers, keywords, numeric literals, and alternative tokens containing alphabetic characters.
