Questions and Answers

What is the primary purpose of repetition in programming?

  • To perform a task only once
  • To repeatedly perform an action until a certain condition is met (correct)
  • To make code more complex
  • To reduce the number of lines of code

What is the difference between a WHILE loop and a DO-WHILE loop?

  • A WHILE loop is used for infinite loops, while a DO-WHILE loop is used for finite loops
  • A WHILE loop is used for sequence, while a DO-WHILE loop is used for selection
  • A WHILE loop checks the condition before the loop, while a DO-WHILE loop checks the condition after the loop (correct)
  • A WHILE loop is used for selection, while a DO-WHILE loop is used for repetition

What is the benefit of using loops in programming?

  • To make the code more complex
  • To reduce the number of lines of code
  • To perform a task only once
  • To efficiently code repetitive tasks (correct)
