Explanation / Answer

TicTacToe pseducode:-
step1:- declare boaed[3][3] and equate its elements to 0;
step2:- ask player 1 to enter row and column number
step3:- check the validity of entered row and column values (check_error())
step4:- check whether the entered location is empty or not (input(string player,int turn))
a) if not ask for another location
b) if yes then mark 'X' on that location
step5:- check win condition (check_state(int turn))
a)if entered move make player 1 win show and end the game
b)if not follow next step
step6:- display board
step7:- ask player 2 to enter row and column number
step8:- check the validity of entered row and column values (check_error())
step9:- check whether the entered location is empty or not (input(string player,int turn))
a) if not ask for another location
b) if yes then mark 'O' on that location
step10:- check win condition (check_state(int turn))
a)if entered move make player 2 win show and end the game
b)if not display board step 2 to 10 till either one win the game or game tie while(continue_playing)
