Activity 1.01: Generating Email Addresses Using Ruby

Solution

1. Define and print the first name variable:

   puts "Enter your first name: "

2. Use the gets.chomp method to allow the user input to be stored in the variables:

   first_name = gets.chomp

3. Similarly, create a new variable for the last name of the user and print it. Also apply gets.chomp on the variable to store the input data:

   puts "Enter your last name: "
   last_name = gets.chomp

4. Lastly, use string interpolation to combine the first and last name with the domain name to generate the email address:

   puts "#{first_name}#{last_name}@rubyprogram.com"
   #Output : 
   Enter your first name: 
   akshat
   Enter your last name: 
   paul
   =>[email protected]

   Expected output:
