It's working fine but
^^^ which is it? Is it working fine, or not :P

as far as I can tell, you are not checking for a win after every move. so if the game ends after 5 moves, it won't work. you need to check for a win after every move.

whats with the creeping right indents on the cases?

how do i do it ....please help :(

copy 99-104 and paste it twice, after each turn, remove it from where it is.

If ever there were a case for decent variable names (not alphabet soup) and indentation, then this program would be it.

Just because you're not allowed to use arrays, it doesn't stop you making a whole bunch of variables that resemble an array.

@salem I run it and it still doesn't give right winning or losing result , it prints player 1 wins when it should print that its a draw



e.g:
OXO
XOX
OXO
Player 1 Wins

It should say that its a draw

Why? O has won because of the left to right diagonal and the right to left diagonal. r1c1 r2c2 r3c3 & r1c3 r2c2 r3c1

Oh sorry my bad ....ThankYou ...Love this community <3

I just reformatted YOUR code for readability.
It's up to you to fix what is now rather more obviously wrong with it.

Consider that TTT has
- 3 winning rows
- 3 winning columns
- 2 winning diagonals

I suppose you could use a bitmapped board to avoid an array. You would need to use 2 bits per position since there are 3 states: empty, O, and X. So you need 18 bits, which will fit in a 32-bit unsigned int.
