According to the university's website design request, students need to order five books, one for each of the five required courses that all students take. You need to design a program that will prompt students for the price of each book and display the total cost for the five books.

The university reassessed its needs for the website design and determined it will no longer require all students to take five classes.

Update the website program to reflect the following changes:

  • Prompt the student for the number of courses being taken
  • Use a while loop to prompt the student for the price of each book based upon the number of classes being taken
  • After the price of each book has been entered, prompt the user for shipping options: delivery or pick-up
  • Use an if statement to add the charges to the total price if the shipping charges are greater than 0
  • Display the total cost

Create a 1/2- to 1-page document containing pseudocode based on the revised program needs.

Create a 1-page flowchart based on the algorithm for the revised program needs.
