SDD

• What are functional requirements in software development?

  Specifications of what the program must do
• What is the purpose of identifying functional requirements?

  To determine what the program is supposed to do
• How does the purpose statement help in identifying functional requirements?

  It clarifies what the program should accomplish
• What are the three main components of functional requirements?

  Inputs, processes, and outputs
• What does the design phase involve in software development?

  Creating a solution to meet functional requirements
• What design notations are discussed in the video?

  • Structured diagrams
  • Flowcharts
  • Pseudocode
• What is the purpose of a structured diagram?

  To break down a problem into sub-steps
• What shape represents a process in a structured diagram?

  Square box
• What shape represents a loop in a structured diagram?

  Oval
• What does a flowchart illustrate in a program?

  The flow of the program from start to end
• What is the symbol for a decision in a flowchart?

  Diamond
• What is pseudocode used for?

  To describe processes in plain language
• How does pseudocode differ from structured diagrams and flowcharts?

  Pseudocode is text-based, not graphical
• What types of errors can occur during programming?

  Syntax, execution, and logic errors
• What is a syntax error?

  A mistake in the programming language syntax
• What causes an execution error?

  Errors that occur while the program runs
• What is a logic error?

  A flaw in the program's expected output
• What is exceptional test data?

  Data that the program should not accept
• What does evaluating a program ensure?

  It meets requirements and is efficient
• What are the criteria for evaluating a program?

  • Fit for purpose
  • Efficient
  • Robust
  • Readable
• What does 'fit for purpose' mean in program evaluation?

  The program meets its functional requirements
• What does efficiency refer to in programming?

  How quickly and easily the code runs
• What is robustness in programming?

  The ability to handle unexpected errors
• What contributes to code readability?

  Meaningful names, whitespace, and comments
• How can internal commentary improve code?

  It explains the code's purpose to developers
• What do we need to describe, exemplify, and implement regarding 1D arrays?

  Fixed and conditional loops
• What standard algorithms are mentioned in the video?

  Input validation and running total
• What is the purpose of a fixed loop?

  To repeat code a set number of times
• What is a running total in programming?

  Constantly adding to a total throughout a loop
• What is the difference between fixed loops and conditional loops?

  Fixed loops repeat a set number of times
• What is input validation in programming?

  Ensuring user input meets specific criteria
• How would you implement input validation in a program?

  Use a while loop to check conditions
• What is the purpose of an array in programming?

  To store multiple pieces of data efficiently
• How do you access an element in an array?

  Using square brackets with the index
• How would you change a value in an array?

  Assign a new value to the specific index
• How can arrays be used with loops?

  To populate and output data efficiently
• What are the three standard algorithms in the software design and development unit?

  Input validation, running total, array traversal
• What is the purpose of input validation?

  To check if user input is acceptable
• How is input validation implemented using a pre-test conditional loop?

  Check score, display error, repeat until valid
• What does a running total do?

  Keeps track of a total inside a loop
