Identifiers

Identifiers provide names for the following language elements:

An identifier consists of an arbitrary number of letters, digits, or the underscore character in the form:

               .------------.
               V            |
>>-+-letter-+----+-letter-+-+----------------------------------><
   '-_------'    +-digit--+
                 '-_------'
 
 
The universal character names for letters and digits outside of the basic source character set are allowed in C++ and at the C99 language level.
