Description: Write a program to calculate square, sphere and cylinder surface area and volume. According to the meaning of problems, a common abstract base class CContaineer an abstract class, which defines requirements in surface area and volume of virtual functions (abstract class does not have the surface area and volume at all). Abstract class defines a public data member radius, this data can be used as the radius of the sphere, square side length of the cylinder base area of the radius. This abstract class derived to describe the three classes in the three classes have a surface area and volume of seeking re-definition version.
