CS 201, Summer 2002


Assignment #10: 10 Points.

Due Date: Friday, 8/9/02.


(2)  1.	Exercise 5.8.

(1)  2.	Exercise 5.21.  Which string manipulation function in Figure
        5.29 performs the same function as mystery1()?

(3)  3. Write a program that uses function strcmp() to compare two
	strings input by the user.  The program should state whether
	the first string is less than, equal to, or greater than the
	second string by alphabetic order.  Test all three cases.**

(4)  4. Write a program which displays a game of tic-tac-toe between
	two human players.  Store the game state in a 3x3 integer 
	array which represents the 9 squares in the game.  Initialize
	the array to all zeros to indicate an empty board.  Prompt 
	for Player 1 to enter a move using two integers, which are the 
	subscripts of an element of the array, and place a 1 in the 
	specified element and then print the game board as an array of
	3 rows and 3 columns.  Repeat for Player 2 by placing a 2 in the
	specified square.  Each move must be to an empty square.
	Alternate players until there is a winner (a row, a column
	or a diagonal with all squares belonging to the same player) or
	until all squares are filled (a draw).  The program should
	congratulate the winner at the conclusion of the game.  
	Use output formatting commands to line up the rows and columns.**


      **For full credit, turn in fully commented program listings,
	including your name and the problem number, and the output
	from test runs exactly as produced by the program.
