Hey @saad90

How do you figure that you have a bug? Any errors, etc

Hello this is Gulshan Negi
Well, you need to add semicolon ; at the end of this line.

do{x=rand()%3;y=rand()%3;}while(board[x][y]!=' ');board[x][y]=COMPUTER

Correct line

do{x=rand()%3;y=rand()%3;}while(board[x][y]!=' ');board[x][y]=COMPUTER;

I hope it will work.
Thanks
