Answer:
Valid Identifiers
What constitutes a legal name in C++ is governed by very simple rules:
A name can have one or more characters;C++ places no limits to the length of an identifier.
Only alphabetic characters, numeric digits, and the underscore character (_) are legal in an identifier.
The first character of an identifier must be alphabetic or an underscore (it cannot be a numeric digit).
Upper case letters are considered distinct from lower case letters; that is, identifiers are case sensitive.
C++ reserved words cannot be used for identifiers.
