Question
Consider the program below: public static void main(String[] args) { int numThings = 0; for (int i = 0; i <= 10; i+=3) { numThings++; } } How many times does the body of the for loop run? Group of answer choices9010114
Solution
The body of the for loop runs 4 times. Here's the step-by-step explanation:
-
The loop starts with
i = 0. This is the first iteration, sonumThingsis incremented once. -
The next iteration is when
i = 3. This is the second timenumThingsis incremented. -
The third iteration is when
i = 6.numThingsis incremented for the third time. -
The final iteration is when
i = 9.numThingsis incremented for the fourth time. -
The loop then tries to run with
i = 12, but this is not less than or equal to 10, so the loop ends.
Therefore, the body of the loop runs 4 times.
