Question

The game Tic-Tac-Toe (or Naughts and Crosses) is an ancient game in which 2 players alternate turns palcing either X's or O's on 3*3 square grid. One Player places X's on the grid and the opposing player places O's. The first player to place 3 consecutive X's (or O's) on any row, column or diagonal of the grid wins the game. If all 9 grid cells are occupied without either player winning, the game is declared a draw. Write a C++ function that takes a two-dimensional 3*3 array of charaacters representin a tic-tac-toe game in progress and determines the current state of the game: player X has won, player O has won, the game is a draw or none of those. Your function should return a single character as follows: 'X' if player X has won the game, 'O' if player O has won the gmae, 'D' if the game is a draw (all cells occupied but neither layer has won) and '*' if none of these conditions exist. (Hint: use a for loop that compares each element of the diagonal with the elements of tits intersecting row and column, then check the diagonals) Write a main() driver to verify that your function is correct. Your main program should do the following: 1) declare a 3*3 character array, 2) use a loop to read in values for each of the 3 rows of the grid (use '-' to indicate a black cell), 3) print out the contents of the grid as 3 rows of 3 values, 4) call your function with the array as an argument, and 5) output an appropriate message declaring the state of the game (as returned by your function).
