Give the output of the following program segment and also mention how many times the loop is executed: int i; for(i = 5; i > 10; i++) System.out.println(i); System.out.println(i * 4);
Topic: Loop that never executes
Previous-year question practice database
Answer
Exam answer
20
The loop is executed 0 times.
Explanation
Test the condition before anything else: i starts at 5, and the condition asks whether i > 10. Since 5 is not greater than 10, the condition is false at the very first test and the body never runs. A for loop is entry-controlled, so zero executions is perfectly possible. The second println is OUTSIDE the loop, since a loop without braces takes only the next single statement. It therefore runs once, printing 5 * 4 = 20. Note that i is still 5, because the update i++ never executed either. Both parts of the question matter — the output AND the count of executions.
