Logical operators (&&, ||, !) in Ruby - Mini Project: Build & Apply

Using Logical Operators in Ruby

📖 Scenario: You are helping a small shop decide if a customer qualifies for a special discount. The shop has simple rules based on the customer's age and membership status.

🎯 Goal: Build a Ruby program that uses logical operators && and || to check if a customer qualifies for a discount.

📋 What You'll Learn

Create variables with exact names and values as instructed

Use logical operators && and || exactly as shown

Print the exact output string as instructed

💡 Why This Matters

🌍 Real World

Stores and businesses often use simple rules to decide if customers get discounts or special offers based on their age or membership.

💼 Career

Understanding logical operators is essential for writing conditions in programs, which is a key skill for any software developer.

1

Create customer data variables

Create a variable called age and set it to 25. Create another variable called is_member and set it to true.

Ruby

# Create variables 'age' and 'is_member' with given values
# Your code here

Need a hint?

Use = to assign values. For is_member, use true without quotes.

2

Create discount eligibility rules

Create a variable called is_senior and set it to false. Create a variable called min_age and set it to 60.

Ruby

age = 25
is_member = true
# Create variables 'is_senior' and 'min_age' with given values
# Your code here

Need a hint?

Remember to use false without quotes for boolean false.

3

Use logical operators to check discount eligibility

Create a variable called qualifies_for_discount that is true if the customer is a member and their age is less than min_age, or if they are a senior. Use && and || operators exactly as shown.

Ruby

age = 25
is_member = true
is_senior = false
min_age = 60
# Create 'qualifies_for_discount' using logical operators
# Your code here

Need a hint?

Use parentheses to group conditions clearly. qualifies_for_discount should be true if either condition is met.

4

Print the discount eligibility result

Print the exact text "Discount eligibility: true" or "Discount eligibility: false" depending on the value of qualifies_for_discount. Use puts and string interpolation with #{}.

Ruby

age = 25
is_member = true
is_senior = false
min_age = 60
qualifies_for_discount = (is_member && age < min_age) || is_senior
# Print the discount eligibility result below
# Your code here

Need a hint?

Use puts and "Discount eligibility: #{qualifies_for_discount}" to print the result.
