Exercise 3.9
Modify program P34_1.cpp to compute the side area, total area, and volume of a cylinder and the
area and volume of a sphere, depending on the choice that the user makes. Your program should
ask users to enter 1 to choose cylinder or 2 for sphere, and display an "invalid choice error" for
other values.
For a cylinder, we want to compute:
Side area: (2*PI*r) * h
Total Area: 2*(PI*r2) + Side area
Volume: (PI*r2)*h
For a sphere, we want to compute:
Surface area: 4*PI*r2
Volume: (4.0/3.0)*PI*r3.
Use overloading whenever possible.
Call your new program Ex39.cpp.
