The Ruby Workshop

3.3 (3)
By: Akshat Paul, Philips, Dániel Szabó , Wallace

Overview of this book

The beauty of Ruby is its readability and expressiveness. Ruby hides away a lot of the complexity of programming, allowing you to work quickly and 'do more' with fewer lines of code. This makes it a great programming language for beginners, but learning any new skill can still be a daunting task. If you want to learn to code using Ruby, but don't know where to start, The Ruby Workshop will help you cut through the noise and make sense of this fun, flexible language. You'll start by writing and running simple code snippets and Ruby source code files. After learning about strings, numbers, and booleans, you'll see how to store collections of objects with arrays and hashes. You'll then learn how to control the flow of a Ruby program using boolean logic. The book then delves into OOP and explains inheritance, encapsulation, and polymorphism. Gradually, you'll build your knowledge of advanced concepts by learning how to interact with external APIs, before finally exploring the most popular Ruby framework ? Ruby on Rails ? and using it for web development. Throughout this book, you'll work on a series of realistic projects, including simple games, a voting application, and an online blog. By the end of this Ruby book, you'll have the knowledge, skills and confidence to creatively tackle your own ambitious projects with Ruby.

1. Writing and Running Ruby Programs

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:
