printing array elements in the programs output.

I'm trying to print all the array elements in their proper columns in the second for(loop).

As general,matrix is printed out as ;
1
2
3
4
5
6
 
for( i = 0 ; i < NUM_ROW ; i++)
{
       for( j = 0 ; j < NUM_COL ; j++) 
              cout << matrix[i][j] << "  " ;
      cout << endl;
}

Dufresne, I appreciate you feedback that worked out just fine. The third for(loop) would give an output of the maximum value cell for each column and divided the cell by the other cells before i applied the changes to the second for(loop) I tried to changing it and had no luck.
