What is the main purpose of the loop do ... end construct in Ruby?
ATo define a method that loops through an array
BTo create an infinite loop that runs until explicitly stopped
CTo conditionally execute code once
DTo iterate over a range of numbers automatically
Step-by-Step Solution
Solution:

  1. Step 1: Understand the loop do ... end construct

    This construct runs the block inside repeatedly without a built-in stop condition.

  2. Step 2: Recognize how to stop the loop

    The loop continues infinitely unless a break statement is used inside to exit.

  3. Final Answer:

    It creates an infinite loop that runs until explicitly stopped -> Option B

  4. Quick Check:

    Loop method purpose = infinite loop [OK]
Quick Trick: loop do runs forever unless you use break [OK]
Common Mistakes:
MISTAKES
  • Thinking loop automatically stops after one iteration
  • Confusing loop with for or while loops
  • Assuming loop iterates over collections by default
