Tic-Tac-Toe (arrays and multidimensional arrays)

C++

Write an interactive program that plays tic-tac-toe. Represent the board as a 3 X 3 character array. Initialize the array to blanks and ask each player in turn to input a position. The first player's position is marked on the board with a O and the second player's position is marked with an X. Continue the process until a player wins or the game is a draw. To win, a player must have 3 marks in a row, in a column, or on a diagonal. A draw occurs when the board is full and no one has won.

Each player's position should be input as indexes into the tic-tac-toe board – that is, a row number, a space, and a column number. Make the program user-friendly.

After each game, print out a diagram of the board showing the ending positions. Keep a count of the number of games each player has won and the number of draws. Before the beginning of each game, ask each player if he or she wishes to continue. If either player wishes to quit, print out the statistics and stop.

Draw a flow-chart or give a set of steps in pseudo-code for the design of your solution before implementing it and include your design. Then implement your program. Call you program tictactoe.cpp.
