C program to uncover whether a given string is an identifier or no longer.
A string is known as an identifier when he follows these rules:
- The first letter would possibly perchance perchance well perchance maintain to be alphabet(both capital or slight i.e. A-Z,a-z) or underscore(_).
- After first letter it contains sequence of alphabet or digits(0-9) or underscore(_) but no longer occupy any particular symbol(#,@,$,%,^,& etc.) and space( ).
