Wk 4 – University Project: Using Arrays [due Mon]
Assignment Content
The university updated its website program design request with a few more features to fit its needs.
Update the website program to reflect the following changes:
Use an array to prompt the user to enter a credit card account number
Use the sequential search algorithm to locate the credit card number entered by the user
If the credit card number is not in the array, display a message indicating the number is invalid
If the credit card number is in the array, display a message indicating the credit card number is valid
Create a 1/2- to 1-page document containing pseudocode based on the revised program needs. Add the pseudocode statements to the existing pseudocode program.
Create a 1- to 2-page flowchart based on the algorithm for the revised program needs. Add the flowchart structure in the existing flowchart for the program.
Submit your assignment.
Wk 5 Discussion – Algorithms and Object-Oriented Classes [due Thurs]
Post a total of 3 substantive responses over 2 separate days for full participation. This includes your initial post and 2 replies to other students.
Due Thursday
Respond to the following in a minimum of 175 words:
Read the following pseudocode class definitions:

End Module
End Class
Class Tree Extends Plant
Public Module message()
Display “I’m a tree.”
End Module
End Class

Assignment Content
Resource: Assignment Grading Guide
For completion of the program, use arrays and files.
Instead of prompting the user for the prices of the book, update the website program to reflect the following changes:
Read the prices into an array from a file using a loop
Use a second loop to sum the values stored in the array after the prices of all the books have been read
Write the content of the array to a second file
Create a 1/2- to 1-page document containing pseudocode based on the revised program needs. Replace the pseudocode statements in the existing pseudocode program.
Create a 1- to 2-page flowchart based on the algorithm for the revised program needs. Replace the flowchart structure in the existing flowchart for the program.
