Rule 14

[derek_farn]

Rule 6.1 and 6.2 refer to 'character values' and 'numeric values;
respectively (the response to a question uses the term 'numeric type').
What exactly is a character
or numeric value? This seems to be a general problem with
the new guidelines in that they use terms without defining them.

I guess we might define a character value as a literal delimited
by single quotes and a numeric value as a literal that
is not delimited by single or double quotes. Rules then need
to be defined for the result of arithmetic operations.
For instance, is char_valu_1 + char_valu_2 a character
or numeric value? What about char_valu_1 + 1? Can I apply
the ++ operator to an object having char type?
