Questions and Answers

What is the main difference between a while loop and a do-while loop?

  • A do-while loop executes the loop once before testing the expression.
  • A do-while loop has a pre-test condition.
  • A do-while loop always executes the loop at least once. (correct)
  • A do-while loop never executes the loop if the expression is false.
  • Which of the following is NOT a type of control structure?

  • Iteration Control Structure
  • Selection Control Structure
  • Repetition Control Structure
  • Arithmetic Control Structure (correct)
  • What is the purpose of a midterm exam in a programming course?

  • To provide additional practice
  • To introduce a new programming concept
  • To assess student understanding of the material (correct)
  • To develop a new algorithm
  • What is the general format of a do-while loop?

    The logic structure of a do-while loop consists of the word 'do' followed by the loop execution statement, then the condition within the parentheses, and finally the loop body.

    Study Notes

    Chapter 8-9: Repetition Control Structures

    'For' and 'Do-While' Structures

    • The do-while loop is a type of posttest loop, which means the loop is executed first, then the expression is tested.
    • The general format of a do-while loop is: do { statement; } while (expression);
    • A semicolon is required after the expression in a do-while loop.
