Question

BlackTom AI · Accepted Answer

The question asks to identify the type of control structure depicted by the given example.
Option a: 'conditional loop.' A conditional loop typically executes while a condition is true or until it becomes false (e.g., while or until loops). The example shown uses a fixed counter range rather than a condition that governs continuation, so this is not best described as a conditional loop.
Option b: 'counter sequence.' This would describe a sequence that merely lists values produced by a counter, but does not imply repeated execution of a block of code. The structure in the example clearly performs repeated actions (printing the counter value) rather than just generating a sequence.
Option c: 'counter repetition.' This is the most accurate: the block of code is executed multiple times, controlled by a counter (from 1 to 3), which demonstrates repetition driven by a counter, i.e., a loop that repeats a set number of times using a counter variable.
Option d: 'conditional selection.' Conditional selection refers to choosing between alternatives based on a condition (like if-else). The example does not show branching based on conditions; it repeatedly prints the index, so this option is incorrect.
In summary, the structure repeats a block of commands a fixed number of times using a counter, which matches the idea of counter repetition rather than a conditional loop, a mere counter sequence, or a conditional selection.
