Which of the following is NOT a type of control structure used in loops?

• A. For Loop
• B. While Loop
• C. Do-While Loop
• D. Print Loop

Answer: (D)

The correct answer is that "Print Loop" is not a recognized type of control structure used in loops. In programming, control structures primarily facilitate the flow of control in loops through specific defined mechanisms. For loops, while loops, and do-while loops represent established categories of control structures. A for loop is used when the number of iterations is known beforehand, while a while loop continues to execute as long as a specified condition remains true. Similarly, a do-while loop guarantees that the loop body runs at least once before checking the condition for subsequent iterations. In contrast, "Print Loop" does not exist as a formal loop structure in programming languages. It may refer to the action of printing inside a loop but does not define a control structure on its own. Therefore, it is clear why this option is not a type of control structure used in loops.
