//	countlines.cpp
//
//	This program reads input from cin, one line at a time,
//	counting the lines as it goes.  When the input ends,
//	the program prints the number of lines.
//
//	The program retrieves words from standard input (cin)
//	until reaching "end of file."  You can run this
//	in two ways from a UNIX prompt:
//
//	(1)		countlines < someInputFileName
//
//	(2)		countlines
//
//	In the second case, you will type the input.  You
//	can type as many lines as you like.  To terminate
//	the input, type CTRL-D at the start of a new line.
