Question

We are going to supply you with a file which contains a very large
number of words. No definitions, just lots of words. It's the kind of
data that you could use to write a spell checker or to gain an unfair
advantage while playing scrabble-like games online with friends (or
enemies).

Your first program ((assume this program is called 'first') will read
in characters or lines of text and count the number of lines, the
number of alphabetic characters (breaking them down into upper case
and lower case), the number of punctuation characters and the number
of numeric characters. Upon termination of input it will report all
of the statistics.

Note: You will recall that fgets and getchar can detect end of file
(EOF). In order to generate an end of file from the keyboard you must
be at the beginning of a line and you can type CTRL/Z on
Windows or CTRL/D on Linux.
