Chapter 7, Problem 7.30E

(Calculating Circle Circumference, Circle Area or Sphere Volume Using Function Pointers) Using the techniques you learned in Fig. 7.28 1, create a text-based, menu-driven program that allows the user to choose whether to calculate the circumference of a circle, the area of a circle or the volume of a sphere. The program should then input a radius from the user, perform the appropriate calculation and display the result. Use an array of function pointers in which each pointer represents a function that returns void and receives a double parameter. The corresponding functions should each display messages indicating which calculation was performed, the value of the radius and the result of the calculation.
