g Modify the program so that it includes struct s for each of the eight shapes that were the subject of Assignment 1. Name these as follows: Square, Rectangle, Circle, Triangle, Cube, Box, Cylinder, and Prism. Include attributes of the double data type for the required dimensions for each (for example, length and width for the Rectangle). Provide a descriptive name for each of these data elements (for example, "radius" instead of "r"). Do NOT include any other attributes, and do NOT include any "member functions" -- avoid the temptation to extend the specifications beyond what is required. If you include attributes for area, volume, or perimeter, you are not doing this right!
