Ruby - Control Flow
You want to print different messages based on a variable status that can be 'open', 'closed', or 'pending'. Which Ruby control flow style is best and why?
AUse multiple <code>if</code> statements because they are simpler
BUse a <code>for</code> loop to iterate over status values
CUse a <code>while</code> loop to repeat checking status
DUse a <code>case</code> statement because it clearly handles multiple fixed choices
Step-by-Step Solution
Solution:
Step 1: Identify the nature of the problem
Status has multiple fixed values and needs different messages for each.
Step 2: Choose the control flow style
A case statement is best for multiple fixed options because it is clear and concise.
Final Answer:
Use a case statement because it clearly handles multiple fixed choices -> Option D
Quick Check:
Multiple fixed choices = case statement [OK]
Quick Trick:Multiple fixed options? Use case statement [OK]
Common Mistakes:
MISTAKES
Using multiple ifs making code longer and less clear
Using loops which are for repetition, not choice
Confusing for loops with case statements
