Writing and Running Your First Ruby Script

Introduction to Ruby Programming Language

Welcome, learners! Are you ready to delve into the fascinating world of Ruby programming language? Ruby is not just any programming language; it's a language made by humans, for humans. It embodies simplicity, intuitiveness, and a closeness to human hearts that sets it apart from other languages.

In this course, we will explore the fundamentals of Ruby, starting with the classic "Hello World" program. If you're new to Ruby or programming in general, fret not! We'll guide you through the installation process and get you set up to write your first lines of code.

So, are you curious to learn how to communicate with machines in pure English rather than in an alien language? Join us on this exciting journey as we uncover the magic of Ruby and unleash your coding potential.

Let's get started with writing your first Ruby program together. Are you ready to say "Hello World" in Ruby?

Main Concepts of Ruby Programming Language

• Ruby Programming Language Overview
  Ruby is described as a programming language created for humans. It is intuitive, easy to understand, and allows for more natural communication with machines in plain English rather than complex machine code.

• Installation of Ruby
  To start programming in Ruby, the first step is to install Ruby on your machine. This can be done by visiting the official website of Ruby and following the installation instructions for Windows, Linux, or Mac operating systems.

• Creating a Hello World Program
  The traditional "Hello World" program is a common starting point in learning a new programming language. In Ruby, this program is written by using the puts command to display the text "Hello World" on the console or command prompt.

• Running a Ruby Program
  Once you have written your code, you can run it through the command prompt or terminal using the ruby command followed by the name of the Ruby file (e.g., hello.rb). This will execute the program and display the output on the screen.

• Completing the Hello World Program
  By successfully creating and running the "Hello World" program in Ruby, you have completed your first step in learning the basics of Ruby programming language. This simple program serves as a foundation for more advanced programming concepts in Ruby.

Practical Applications of Ruby Programming Language

Step 1: Install Ruby

• Visit the official website of Ruby.
• Follow the instructions to install Ruby on your Windows, Linux, or Mac machine.

Step 2: Set Up Working Directory

• Choose a directory of your choice.
• Open your command line or terminal emulator.
• Use cd to navigate to your preferred working directory.
• Create a file named hello.rb.

Step 3: Write Your First Program

• Open the hello.rb file in a text editor (e.g. Notepad++).
• Add the following code:

  puts "hello world"
  

• Save the file.

Step 4: Run Your Program

• Go back to the command prompt.
• Run the following command:

  ruby hello.rb
  

• You should see the output "hello world" displayed on the screen.
