Help me fix this code I tried to make the traffic light like the traffic light on the picture.

You are to write a program that allows the user to draw a simple house using 5 mouse clicks. - The first two clicks will be the opposite corners of the rectangular frame of the house. - The third click will indicate the center of the top edge of the rectangular door. The door should have a total width that is 1/5 of the width of the house frame. The sides of the door should extend from the corners of the top down to the bottom of the frame. - The 4th click will indicate the center of a square window. The window is as wide as the door. (A change from the original book program.) - The last click will indicate the peak of the roof. The edges of the roof will extend from the point at the peak to the corners of the top edge of the house frame. Make the lines of the roof edge green. (Another change from the original book program.)
