   // Print the prices
   for (row=0; row<2; row++)
   {
      if (row == 0)
      {
         cout << "3-1/2\"\t";
      }         // Need \" to print quotation.
      else
      {
         cout << "5-1/4\"\t";
      }
      for (col=0; col<4; col++)    // Print the current row.
      {
         cout << setprecision(2) << "$" << disks[row][col] << "\t\t";
      }
      cout << "\n";    // Print a newline after each row.
   }
