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 arrow_base_height. (1 pt) (2) Modify the given program to use a loop to output an arrow base of width arrow_base_width. (1 pt) (3) Modify the given program to use a loop to output an arrow head of width arrow_head_width. (2 pts) (4) Modify the given program to only accept an arrow head width that is larger than the arrow base width. Use a loop to continue prompting the user for an arrow head width until the value is larger than the arrow base width. (1 pt)
