Undertake ONE of the following programming projects. You should keep
a track of the changes to your program using RCS. You should submit
the RCS ",v" files with submit-work.

Project 1)
	a) Write a program which chooses a random int between 1 and 100
	which you have to guess. When you input a guess it prints H if
	you need to go higher, L is you need to go lower or G if you've
	got it.
	b) Write a program which tries to guess an int you are thinging
	of between 1 and 100. It should prompt you with guesses and you
	should answer H, L or G as above.
	c) Using fork(), exec(), pipe() and dup2() join these programs
	together so they "play" one another.

Project 2)
	a) Write a program which reads in a word, opens /usr/share/dict/words
	and searches for the word. It should print "OK: word" if it finds the
	word or "UNKNOWN: word" if id doesn't find it. It should keep reading
	words untill it runs out of input.

	b) Modify the above program so that it forks a child to do the
	open, search and print. The parent should immediately prompt for
	another word. Try searching for "zebra" and then "apple" by putting
	the input in a file.

	c) Use the wait3() system call with the WNOHANG option to reap the
	zombies in the parent.
