comparing strings in a tic tac toe game

[gemacky]

I am trying to write a test to see if a tic tac toe space is occupied.
char board[3][3];
int row;
int col;
cout << " Enter row";
cin >> row
cout << "Enter col":
board[row][col]=='X';
if(!strcmp(board[col],"O"))
{
cout << "Space already taken";
}
Any ideas please?

hi,
Why are you checking only for O?

strcmp returns 0 if they match,so you could use like:

if(strcmp(board[row][col],"O")==0||strcmp(board[row][col],"X")==0)

Why are you bothering to use strcmp? strcmp is used when you will have multiple characters forming a string. But what you are doing is comparing individual characters: thus, you can write

if (board[row][col] == 'X') {
   // ...
}

and will have no problems.
