[Solved] Identify the error in this Ruby code using an until loop: i = 0 until i — Ans: The loop condition should be > instead of < | Ruby

Ruby - Loops and Iteration

Identify the error in this Ruby code using an until loop:

i = 0
until i < 5
  puts i
  i += 1
end

AInfinite loop because i never changes

BMissing do keyword after until condition

CThe loop condition should be > instead of <

DNo error, code runs correctly

Step-by-Step Solution

Solution:

Step 1: Analyze the loop condition
until i < 5 with i=0: 0 < 5 is true, so condition true and loop never executes.
Step 2: Identify the correct error
Syntax is fine (newline ok without do). Logic error: condition backwards. Should be until i > 4 or similar. The loop condition should be > instead of < identifies this.
Final Answer:
The loop condition should be > instead of < -> Option C
Quick Check:
Wrong condition direction: loop never runs [OK]

Quick Trick: Flip < to > for until when adapting while logic [OK]
