Complete the Lab 9-5, "Programming Challenge 1 -- Going Green," of Starting Out with Programming Logic and Design. Note: You are only required to create the flowchart for this activity; however, notice how the pseudocode compares to the given Python code for this assignment. 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.

In this assignment, the goal is to update an existing program designed to verify credit card numbers through array storage and sequential search algorithm. Although only a flowchart is required, understanding the pseudocode and algorithm adjustments is essential to accurately depict the revised process. This task involves creating a detailed pseudocode reflecting the new features, especially the use of an array for user input and validation, and then developing an updated flowchart that incorporates these modifications.

Pseudocode for the Revised Program

The program begins by initializing an array with predefined valid credit card numbers. It then prompts the user to enter a credit card number, storing this input. The sequential search algorithm is applied to scan through the array to locate the entered number.

If the number is found within the array, the program outputs a message indicating the credit card number is valid. If the search reaches the end of the array without finding a match, the program outputs that the credit card number is invalid.

Below is the pseudocode encapsulating these steps:

START


DECLARE array of valid credit card numbers


PROMPT user to enter a credit card number


READ user input into variable 'cardNumber'


SET 'found' to FALSE


SET 'index' to 0


WHILE 'index' 

IF array['index'] == 'cardNumber' THEN


SET 'found' to TRUE


ELSE


INCREMENT 'index' by 1


END IF


END WHILE


IF 'found' == TRUE THEN


DISPLAY "Credit card number is valid."


ELSE


DISPLAY "Invalid credit card number."


END IF


END

Flowchart Structure for the Revised Program

The flowchart begins with a start symbol, followed by initializing the array of stored credit card numbers. The program then prompts the user for input, which is stored in a variable. The flow proceeds with a decision node checking if the array has been fully searched or if a match has been found. If a match is found, an output indicates the number's validity; otherwise, the search continues until the end of the array. If no match is found after checking all entries, the program outputs that the number is invalid. Finally, the flowchart concludes with an end symbol.

The flowchart visually represents these steps with standard flowchart symbols: oval for start/end, parallelogram for input/output, rectangle for processing, and diamond for decision points. Incorporating these into the existing flowchart structure maintains clarity and precision, illustrating the algorithm's logic, including the sequential search through an array.
