Questions and Answers

What is recursion in computer programming?

  • A function that calls a function that calls it indirectly
  • A function that only calls itself
  • A function that calls another function which in turn calls it again (correct)
  • A function that never calls itself

    • What is the purpose of activation record in recursion?

  • To keep information about local variables, formal parameters, return address and all information passed to the caller function (correct)
  • To keep track of the iteration count
  • To store the result of the recursive function
  • To keep track of the number of recursive calls made by the function

    • Why is recursion preferred over iteration?

  • Recursion is less efficient than iterations
  • Recursion is harder to implement than iterations
  • Recursion is not supported by most programming languages
  • Recursion makes a program more readable and is more efficient than iterations (correct)
