Ruby - Control Flow

Write a Ruby if-elsif-else structure that prints "Child" if age is less than 13, "Teen" if age is between 13 and 19 inclusive, and "Adult" otherwise. Which code is correct?

Aif age < 13 puts "Child" elsif age >= 13 && age <= 19 puts "Teen" else puts "Adult" end

Bif age <= 13 puts "Child" elsif age > 13 && age < 19 puts "Teen" else puts "Adult" end

Cif age < 13 puts "Child" elsif age > 13 && age < 19 puts "Teen" else puts "Adult" end

Dif age < 13 puts "Child" elsif age >= 13 || age <= 19 puts "Teen" else puts "Adult" end

Step-by-Step Solution

Solution:

Step 1: Check conditions for each age group
Child: age < 13, Teen: 13 <= age <= 19, Adult: else.
Step 2: Verify logical operators and ranges
if age < 13 puts "Child" elsif age >= 13 && age <= 19 puts "Teen" else puts "Adult" end correctly uses age >= 13 && age <= 19 for Teen.
Final Answer:
if age < 13 puts "Child" elsif age >= 13 && age <= 19 puts "Teen" else puts "Adult" end -> Option A
Quick Check:
Use && for range checks in elsif = A [OK]

Quick Trick: Use && to combine conditions in elsif [OK]

Common Mistakes:

MISTAKES

Using || instead of &&
Wrong boundary operators
Overlapping conditions
