I need help identifying how the members and functions work to answer the questions below. I am having troubles understanding this concept. I am learning constructors and deconstructors along with inline and hiding information. I feel lost trying to answer these questions. Can I get direction on how to proceed? Write the definition of the member function set so that the instance variables are set according to the parameters. Write the definition of the member function manipulate that returns a decimal number as follows: If the value of description is "rectangle", it returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of description is "sphere", it returns the volume of the sphere with radius first; if the value of description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns the value -1. Write the definition of the function print to print the values of the instance variables and the values returned by the function manipulate. For example, if description = "rectangle", first = 8.5, and second = 5, it should print: rectangle: length = 8.50, width = 5.00, area = 42.50
