Zip for combining arrays in Ruby - Mini Project: Build & Apply

Zip for combining arrays

📖 Scenario: You are organizing a small event and have two lists: one with guest names and another with their meal choices. You want to pair each guest with their meal choice to prepare name cards.

🎯 Goal: Build a Ruby program that combines two arrays using zip to pair each guest with their meal choice.

📋 What You'll Learn

Create an array called guests with the exact values: "Alice", "Bob", "Charlie"

Create an array called meals with the exact values: "Salad", "Steak", "Pasta"

Create a variable called guest_meal_pairs that uses guests.zip(meals) to combine the arrays

Print the guest_meal_pairs array

💡 Why This Matters

🌍 Real World

Combining lists of related information, like pairing guests with their meal choices, is common in event planning and data organization.

💼 Career

Understanding how to combine arrays helps in data processing, report generation, and building user-friendly displays in many programming jobs.

1

Create the guests array

Create an array called guests with these exact values: "Alice", "Bob", "Charlie"

Ruby

# Create the guests array with the names
# Your code here

Need a hint?

Use square brackets [] to create an array and separate names with commas.

2

Create the meals array

Create an array called meals with these exact values: "Salad", "Steak", "Pasta"

Ruby

guests = ["Alice", "Bob", "Charlie"]
# Create the meals array with the meal choices
# Your code here

Need a hint?

Use square brackets [] to create an array and separate meal names with commas.

3

Combine the arrays using zip

Create a variable called guest_meal_pairs that uses guests.zip(meals) to combine the two arrays

Ruby

guests = ["Alice", "Bob", "Charlie"]
meals = ["Salad", "Steak", "Pasta"]
# Combine guests and meals using zip
# Your code here

Need a hint?

Use the zip method on the guests array and pass meals as argument.

4

Print the combined pairs

Print the guest_meal_pairs array to show the paired guests and meals

Ruby

guests = ["Alice", "Bob", "Charlie"]
meals = ["Salad", "Steak", "Pasta"]
guest_meal_pairs = guests.zip(meals)
# Print the guest_meal_pairs array
# Your code here

Need a hint?

Use puts guest_meal_pairs.inspect to display the combined array.
