Questions and Answers

What is the main purpose of a 'while' loop in programming?

  • To initialize loop variables
  • To create a loop that repeats for a fixed number of iterations
  • To execute a block of code as long as a certain condition is true (correct)
  • To skip the loop entirely if the condition is not met
  • What happens if the condition in a 'while' loop is never false?

  • The loop will not execute at all
  • The code inside the loop will be skipped
  • The loop will execute forever in a loop known as an infinite loop (correct)
  • The loop will execute once and then terminate
  • What is one of the essential steps for implementing a count-controlled loop?

  • Changing the loop type to 'for' loop instead of 'while' loop
  • Initializing the loop variable (correct)
  • Using multiple conditions within the loop
  • Testing the loop variable to determine if the condition is true
  • When should you change the loop variable within the body of a 'while' loop?
