(a) Explain two differences between an Algorithm and a Flowchart.
(b) List three examples of utility programs.
(c) Draw a flowchart of the stops to be used in updating a customer's balance.
(a)
Representation: An algorithm is a step-by-step procedure for solving a problem, whereas a flowchart is a graphical representation of an algorithm that uses symbols to depict different operations.
Detail level: An algorithm is typically written in a programming language and provides a higher level of detail in terms of the logic and syntax required for the program to run, while a flowchart is a visual representation that provides a broad overview of the steps involved in the algorithm.
(b)
Disk cleanup: A utility program that frees up disk space by removing temporary files, internet cache files, and other unnecessary files from your computer.
Antivirus software: A utility program that protects your computer from viruses, malware, and other malicious software.
Compression software: A utility program that compresses and decompresses files and folders to save disk space and make it easier to transfer large files.
(c)
A flowchart for updating a customer's balance could involve the following steps:
Start the program.
Ask the user for the customer's name.
Retrieve the customer's balance from a database.
Ask the user for the amount to be added to the balance.
Add the amount to the customer's balance.
Update the customer's balance in the database.
Display the updated balance to the user.
End the program.
This flowchart outlines a simple process for updating a customer's balance. It begins by asking the user for the customer's name, retrieves the current balance from a database, and prompts the user for the amount to be added. The program then adds the amount to the current balance, updates the balance in the database, and displays the updated balance to the user before ending the program.
