Question

please complete the following program in c++:

In this homework assignment you will modify the program you have developed in Homework Assignment

1 by implementing the following:

1- Your program will ask the user to choose to either Compute and Display Surface Areas of Hemispheres and their Average (Choice 1) or to Compute and Display Volumes of Hemispheres and their Average (Choice 2). The program will only perform the chosen operation. (Hint: use a character variable to read the character 1 or 2 to safeguard against improper entries)

2- Your program will ask the user to specify how many Hemispheres’ Surface Areas or Volumes they would like to be computed; your program then will prompt for and read as many input information as needed based on how many Hemispheres’ Surface Areas or Volumes the user want to be computed. The program will then compute and display the Surface Areas or Volumes, and their average. The results must be clearly labeled with proper units and format (same format as specified in Homework Assignment 1) – See Sample Run below.

3- Once the results are displayed, the program must ask its users if they want to compute more Hemispheres’ Surface Areas or Volumes (Enter Y or y to Run the Hemisphere Surface Area / Volume Calculator) or if they want to quit (Enter N or n to Quit). If the users want to compute more Hemispheres’ Surface Areas or Volumes the program will repeat until the users quit.

Note:

For modifications 1 and 3 above when the users enter anything other than 1 or 2 for part 1, or anything other Y/y or N/n for part 3 then they will repeatedly receive an error message prompting them to enter a proper value until they enter such a value.

Similarly, for modification 2, the users must enter 1 or more Hemisphere information to be computed otherwise they should be repeatedly prompted with an error message until they provide a valid entry. Also, for input information (Hemisphere Diameter) the input must be greater than or equal to zero, otherwise the user will receive an error message repeatedly until they enter proper values.

Do NOT use any programming statements and/or techniques that have not been covered in this class (i.e., functions, classes, arrays, pointers ... etc.)
