Ruby - Control Flow

Which of the following is the correct syntax for a case/when statement in Ruby?

case x
  when 1
    puts "One"
  when 2
    puts "Two"
  else
    puts "Other"
end

Acase x when 1 puts "One" when 2 puts "Two" else puts "Other" end

Bcase x { when 1: puts "One" when 2: puts "Two" else: puts "Other" }

Cswitch(x) { case 1: puts "One" case 2: puts "Two" default: puts "Other" }

Dif x == 1 then puts "One" elsif x == 2 then puts "Two" else puts "Other" end

Step-by-Step Solution

Solution:

Step 1: Check Ruby case/when syntax
Ruby uses case followed by when clauses and ends with end. No braces or colons are used.
Step 2: Compare options
case x when 1 puts "One" when 2 puts "Two" else puts "Other" end matches Ruby syntax exactly. Options B and C use braces and colons like other languages. if x == 1 then puts "One" elsif x == 2 then puts "Two" else puts "Other" end is an if/elsif, not case/when.
Final Answer:
case x when 1 puts "One" when 2 puts "Two" else puts "Other" end -> Option A
Quick Check:
Ruby case/when uses no braces or colons [OK]

Quick Trick: Ruby case/when uses no braces or colons, just end [OK]
