• Question 141:

  Which line is a loop variable update statement in the sample code?

  integer h = 0 do Put "What is the password?" to output string userInput = Get next input if userInput != pwd then Put "Incorrect." to output h = h + 1 while (userInput != pwd) and (h <= 10) if userInput == pwd then Put "Access granted." to output else Put "Access denied." to output

  A. integer h = 0
  B. h = h +1
  C. (userInput !=pwd) and (h
  D. if userInput == pwd
  B. h = h +1

  In programming, a loop variable update statement is used to modify the loop variable's value with each iteration of the loop. This is crucial for the progression and eventual termination of the loop. The statement h = h + 1 is a classic example of a loop variable update statement. It increments the value of h by 1, ensuring that the loop can move towards its completion condition. Without such an update, the loop could potentially continue indefinitely, leading to an infinite loop. References: The answer is based on standard programming conventions where loop variables are updated within the body of the loop to avoid infinite iterations. This practice is consistent across various programming languages and is a fundamental concept taught in programming and computer science courses.
