Ruby - Control Flow
Given a variable score that can range from 0 to 100, which Ruby control flow style is most suitable to clearly handle multiple score ranges like 0-59, 60-79, and 80-100, and why?
AUsing multiple nested <code>if</code> statements to check each range separately
BUsing a <code>case</code> statement with range conditions for clear and readable branching
CUsing a single <code>if</code> statement with complex logical operators
DUsing a loop to iterate over score values and print messages
Step-by-Step Solution
Solution:
Step 1: Identify the need for multiple range checks
Score ranges require distinct handling for each interval.
Step 2: Evaluate control flow options
A case statement with ranges is concise and improves readability compared to nested if or complex conditions.
Step 3: Consider loops
Loops are not appropriate here since the task is conditional branching, not iteration.
Final Answer:
Using a case statement with range conditions for clear and readable branching -> Option B
Quick Check:
Ranges in case simplify multi-branch conditions [OK]
Quick Trick:Use case with ranges for clear multi-branch conditions [OK]
Common Mistakes:
MISTAKES
Using nested ifs which reduce readability
Trying to handle all conditions in one if statement
Using loops for conditional branching
