Question

This loop will run at least once: ___________

Options:
a. While
b. For
c. Do-While
d. None of the above

Answer 1

The 'Do-While' loop is designed to run at least once before evaluating its condition, ensuring that the code block inside it is executed at least one time.

Step-by-step explanation:

The loop that will run at least once regardless of the condition at the start of the loop is the Do-While loop. This is because a Do-While loop executes the code block once before checking the condition. In contrast, a While loop and a For loop first check the condition before executing the code block, which means they might not run at all if the condition is false from the beginning.
