[lex.token] (original) (raw)
There are five kinds of tokens: identifiers, keywords, literals,13operators, and other separators.
Blanks, horizontal and vertical tabs, newlines, formfeeds, and comments (collectively, “whitespace”), as described below, are ignored except as they serve to separate tokens.
[Note 1:
Whitespace can separate otherwise adjacent identifiers, keywords, numeric literals, and alternative tokens containing alphabetic characters.
