Create a main that declares an array of three rectangle pointers. Each element should be a different kind of object that "is a rectangle (rectangle, cube, colored rectangle), then separately run the three different constructors (you can send it any values that match up with the argument constructors) and assign to each element of the array (ex. spot 0 rectangle, spot 1 cube, spot 2 colored rectangle). Then in a for loop, print the address of each object that "is a" rectangle (the address in the pointer) and then use dynamic binding to call the print function to print each of the objects in the array
