7.10: tic tac toe (sort of) write a program that will allow two users to play tic-tac-toe. the program should ask for moves alternately from player x and player o. the program displays the game positions as follows: 123 456 789 the players enter their moves by entering the position number (a single digit, 1-9) they wish to mark. after each move, the program re-displays the changed board. a sample board configuration is as follows: xxo 456 o89 sample run #1: ./etest interactive session 1 2 3 4 5 6 7 8 9 enter move: 1 x 2 3 4 5 6 7 8 9 enter move: 2 x o 3 4 5 6 7 8 9 enter move: 3 x o x 4 5 6 7 8 9 enter move: 4 x o x o 5 6 7 8 9 enter move: 5 x o x o x 6 7 8 9 enter move: 6 x o x o x o 7 8 9 enter move: 7 x o x o x o x 8 9 enter move: 8 x o x o x o x o 9 enter move: 9 x o x o x o x o x game over!
