(½ Mark for declaring class header correctly)
(½ Mark for declaring data members correctly)
(1 Mark for defining CalVolume() correctly)
(½ Mark for taking inputs of Radius, Type and Height in GetValues())
(½ Mark for invoking CalVolume() inside GetValues())
(½ Mark for defining ShowAll() correctly)
(½ Mark for correctly closing class declaration with a semicolon ; )

NOTE:
● Marks to be awarded for defining the member functions inside or
outside the class
● Marks not to be deducted for replacing the Formulae for calculating
