Placing the posttest loop inside a selection structure allows you to test an initial condition before entering the loop, ensuring that the loop is only executed if the condition is met. This is because posttest loops (like do-while loops in some languages) check the condition after the loop body has executed, so an initial test using a selection structure (like an if statement) can determine if the loop should run at least once.
