if else problem

i am having trouble trying to convert a 0 or 1 into an X or O.
here is my print function of the program

Code:

char print(int row1col1, int row1col2, int row1col3)
{
   char X;                
   char O;     
             
   if (row1col1 == 1) 
      row1col1 = X;          
   else row1col1 = O;   
                             
   if (row1col2 == 1)            
      row1col2 = X;          
   else row1col2 = O;
                          
   if (row1col3 == 1)
      row1col3 = X;
   else row1col3 = O;   
                       
   printf("\n|%s| |%s| |%s|", row1col1, row1col2, 
   row1col3);
}

when i dont try and convert, i get a randomly selected 0 and 1's so i know i am creating it right but when i use the if else above i get a
|(null)| |(null)| |(null)| as output. so please help.....

X and O are undefined. Maybe try:

Code:

   char X='X';                
   char O='O';

Or, simply do:

Code:

   if (row1col1 == 1) 
      row1col1 = 'X';          
   else row1col1 = 'O';

etc.

row1col1, row1col2, row1col3 aren't strings but the printf makes them out to be.

yea that worked thanks everyone
