Once the logic enters the body of a structured loop, the entire loop must execute.
Explanation:
The structured loop is characterized by this property only. A loop is said to be structured only when it has a single exit point.
Unstructured loops can always be broken by using the break statement often occurring after a test condition. Structured loops don not have any provision for the break statement.
Once the loop starts to execute, it will complete all the iterations no matter what conditions arise. There is only one exit when the test condition fails and the loop body does not execute.
