Program C.
This project must use a two-dimensional array (see Section 8.5 in the textbook).
The program should allow two players to play tic-tac-toe on the same keyboard.
A 3 X 3 two-dimensional array should be initialized with all blank ( 'b' ) characters.
The X player is first prompted to input two integers, each in the range 1 to 3 for the row and column of to place an X. The program then prints out the new board.
The O player is then prompted to input row and column integers and the new board printed out.
The X and Y players continue to alternate until a sentinel value (any integer outside the range 1 - 3) is entered.
