Ruby - Loops and Iteration

What is the main difference between a while loop and an until loop in Ruby?

A<code>while</code> runs while the condition is true; <code>until</code> runs while the condition is false

B<code>while</code> runs only once; <code>until</code> runs multiple times

C<code>while</code> runs when condition is false; <code>until</code> runs when condition is true

D<code>while</code> and <code>until</code> are exactly the same

Step-by-Step Solution

Solution:

Step 1: Understand while loop behavior
The while loop runs as long as its condition is true.
Step 2: Understand until loop behavior
The until loop runs as long as its condition is false (it stops when condition becomes true).
Final Answer:
while runs while the condition is true; until runs while the condition is false -> Option A
Quick Check:
Loop condition logic = B [OK]

Quick Trick: Until runs while false, while runs while true [OK]
