This program outputs a downwards facing arrow composed of a rectangle and a right triangle. the arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. (1) modify the given program to use a loop to output an arrow base of height arrowbaseheight. (1 pt) (2) modify the given program to use a loop to output an arrow base of width arrowbasewidth. use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow base. (1 pt) (3) modify the given program to use a loop to output an arrow head of width arrowheadwidth. use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow head.
