C++ also reserves a number of words that can be used as alternative names for various operators. These alternative names are provided to support character sets that do not support the standard set of C++ operator symbols. These names, listed in Table 2 below, also may not be used as identifiers:

C++ Operator Alternative Names

and	bitand	compl	not_eq	or_eq	xor_eq
and_eq	bitor	not	or	xor

In addition to the keywords, the standard also reserves a set of identifiers for use in the library. Identifiers cannot contain two consecutive underscores, nor can an identifier begin with an underscore followed immediately by an upper-case letter. Certain identifiers those that are defined outside a function may not begin with an underscore.
