w doesn't point anywhere, yet you're reading into it!

You might replace

	char* w;

by

	char w[200];

or some suitably large buffer.

Of course, what you'd really like to be able to say is

	String w;

	while (cin >> w) { ...
	};

and have the String class take care of memory allocation for you.

This is left as an exercise to the reader.
