easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recall Ruby for loop syntax
Ruby uses 'for variable in range do ... end' or without 'do'.Step 2: Check each option
for i in 1..3 do puts i end uses 'do' and 'end' correctly. for i in 1..3 puts i end misses 'do'. for i in 1..3 { puts i } uses braces which is invalid. for (i = 1; i <= 3; i++) puts i end uses C-style syntax which is wrong in Ruby.Final Answer:
