Questions and Answers

What is a loop in programming?

  • A statement that only runs once and then terminates
  • A function that stops the program from executing further
  • A variable that stores multiple values
  • A command that tells the program to repeat a certain action until a specific condition is met (correct)

    • What is Scratch programming primarily designed for?

  • Developing complex enterprise applications
  • Creating machine learning algorithms
  • Writing low-level system software
  • Teaching coding concepts to beginners in a fun and interactive way (correct)

    • Which type of loop in Scratch is useful when something needs to happen before the loop should stop?

  • Repeat Until Loop (correct)
  • While Loop
  • Forever Loop
  • Repeat x number of times Loop
