Write a format string that handles the display of three data items in three columns. The first column should be 20 spaces wide, and it should print a left-aligned string. The second column should be 10 spaces wide, and it should print a right-aligned integer. The third column should be 16 spaces wide, and it should print a right-aligned floating-point number in scientific format with 6 decimal places. Your format string should cause the screen’s cursor to move to the next line after printing the third data item.
