Which description best fits a For loop?

• A. It prints to the screen
• B. It repeats a fixed number of times based on a start value, an end value, and a step
• C. It runs until a condition is met
• D. It performs a function call

Answer: (B)

A For loop is a control structure that repeats a block of code a fixed number of times, using a counter that starts at a chosen value, increments by a fixed step, and stops when it reaches or passes an end value. This behavior matches the idea of repeating a set number of iterations determined by start, end, and step. That’s why describing it as repeating a fixed number of times based on those three values is the best fit. Printing to the screen can happen inside a loop, but that doesn’t define the loop itself. A loop that runs until a condition is met describes a different pattern (often a while loop). Performing a function call can occur inside any loop, so it doesn’t uniquely define the for loop either.
