In a For loop, which component determines how many times the loop runs?

• A. The step size
• B. All of the above
• C. The starting value
• D. The ending value

Answer: (B)

The number of times a for loop runs is determined by three things: where the counter starts, where it stops, and how much it increases each time. You begin at the starting value, you keep looping until you reach or pass the ending value, and you move the counter by the step size on every iteration. Because each of these controls how many steps fit into the range, all three influence the total count. If the step is large or the end is close to the start, there are fewer iterations; changing the direction with a negative step or an inclusive/exclusive end can also change the result. So all of these components together determine how many times the loop runs.
