String creation (single and double quotes) in Ruby - Mini Project: Build & Apply

String creation (single and double quotes)

📖 Scenario: You are creating a simple program that stores greetings using different types of quotes in Ruby. This will help you understand how to create strings with single and double quotes.

🎯 Goal: Build a Ruby program that creates strings using both single and double quotes, then prints them.

📋 What You'll Learn

Create a string variable using single quotes

Create a string variable using double quotes

Print both string variables

💡 Why This Matters

🌍 Real World

Creating strings with different quotes is common when handling text data, user messages, or code that needs quotes inside strings.

💼 Career

Understanding string creation is essential for any programming job, especially when working with text processing, web development, or scripting.

1

Create a string with single quotes

Create a string variable called greeting_single and set it to the text 'Hello, world!' using single quotes.

Ruby

# Create a string variable called greeting_single using single quotes
# Your code here

Need a hint?

Use single quotes around the text to create the string.

2

Create a string with double quotes

Create a string variable called greeting_double and set it to the text "Hello, Ruby!" using double quotes.

Ruby

greeting_single = 'Hello, world!'
# Create a string variable called greeting_double using double quotes
# Your code here

Need a hint?

Use double quotes around the text to create the string.

3

Use both strings in a loop

Use a for loop with the variable greeting to iterate over the list [greeting_single, greeting_double] and print each greeting inside the loop.

Ruby

greeting_single = 'Hello, world!'
greeting_double = "Hello, Ruby!"
# Use a for loop to print each greeting
# Your code here

Need a hint?

Use for greeting in [greeting_single, greeting_double] and inside the loop use puts greeting to print.

4

Print both greetings separately

Write two puts statements to print the variables greeting_single and greeting_double separately.

Ruby

greeting_single = 'Hello, world!'
greeting_double = "Hello, Ruby!"
for greeting in [greeting_single, greeting_double]
  puts greeting
end
# Print greeting_single and greeting_double separately
# Your code here

Need a hint?

Use puts greeting_single and puts greeting_double to print each string.
