Hi! C++ program again. Help me, please! Each problem - different program. Thank you!

Problem B1

The volume of a cone is given by the formula: V = r2 h / 3

For the value of use: const double PI = 3.14159265358979323846;

Declare a structure named: Cone containing:

height	a double, the height of the cone
radius	a double, the radius of the base of the cone

Create the following functions:

main

Contains three variables:

A pointer named ptr which points to a Cone structure

A double named height

A double named radius

Uses new to obtain space for the data structure

Calls the the input, setUp, and output functions

Deletes the space that was obtained using new

input:

Takes the height of the cone and radius of the base as reference parameters

Reads the height and radius from the user

Has a return type of void

setUp:

Takes three parameters by value: height, radius, and a pointer to the Cone

Puts the data into the data structure

Has a return type of void

getVolume:

Takes one parameter by value: a pointer to the Cone

Computes the volume

Returns the volume

output:

Takes one parameter by value: a pointer to the Cone

Calls the getVolume function to get the volume

Prints the height, radius, and volume in a neat format

Has a return type of void

Put the main function first. Use the function and variable names specified above. Arrange the functions in the order listed above.

Test your program with the following data:

height	6
radius	2

Problem B2

Repeat problem B1 with the following changes:

Make Cone a class rather than a struct. Make the height and radius in the class Cone private. Make setUp a public member function in the class Cone. Make getVolume a pubic member function in the class Cone. Make output a public member function in the class Cone. The main and input functions will remain global functions, not part of the Cone class. The main function will call the input, setUp, and output functions. The return types will all be unchanged.

The parameter lists will change for some of the functions:

main unchanged

input unchanged

setUp two parameters by value: height, radius

getVolume no parameters

output no parameters

Test with the same data.
