Changing an input to output a "space"

sh129951 (24)
I've been fumbling around with making this tic tac toe program work correctly. When the user inputs a " . " (period) in the array, i need it to just print a blank space.

eg:

input:

oxo
.xo
.xo

output:

O X O
_ X O
_ X O

underscores were to show formatting on the forum

if( board[ row ][ column ] == '.' )
    std::cout << ' ';
else
    std::cout << board[ row ][ coloum ];

Thank you Lynx876. After using what you said and putting it in the nested for loops in the print function, I got it to print blank spaces throughout the array if the whole thing is filled with period.

No problem. (:
