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.

The task involves updating a website program to incorporate features for validating credit card account numbers using an array and sequential search algorithm. This process requires several steps, including creating pseudocode and developing a flowchart that visually represents the program's logic. The primary goal is to enable the system to prompt the user for a credit card number, search for this number within a predefined array, and then provide appropriate feedback based on whether the number exists in the array.

Initially, the program must declare and initialize an array containing valid credit card numbers. This array acts as the data source against which user input will be verified. The program then prompts the user to enter a credit card account number, capturing the input for processing. The core of the algorithm utilizes sequential search to examine each element of the array in order. If a match is found, the program will display a message confirming that the credit card number is valid. If the search completes without finding a match, the program will inform the user that the number is invalid.

The pseudocode for this revised program simplifies the logic into clear, step-by-step instructions. It begins with the array declaration and initialization, followed by prompting the user for input. Using a loop structure, it iterates through each array element, compares it with the user-entered number, and sets a flag or directly outputs the validity message upon finding a match. If no match is found after completing the iterations, it displays an invalid message.

Similarly, the flowchart visually represents these procedures with standard flowchart symbols, such as cylinders for input/output, rectangles for processes, and diamonds for decisions. The flowchart illustrates the sequence starting from array initialization, user prompt, sequential search through array elements, condition checks for matches, and respective outputs. Incorporating these elements ensures that the program is both logically sound and user-friendly, providing clear validation feedback.

By integrating these modifications—prompting for user input, array utilization, sequential search, and validation messages—the website program enhances its functionality and user experience. Developing both pseudocode and flowchart documentation ensures a comprehensive understanding of the program's logic, facilitating future updates and troubleshooting.
