EASY WAYS TO PRINT HELLO WORLD IN RUBY

Introduction:

Ruby is a dynamic, open-source programming language known for its simplicity and ease of use. It is widely used for web development, scripting, and automation. One of the first programs beginners write in any language is the “Hello, World!” program, which simply outputs a greeting to the screen. This example will guide you through writing and understanding a basic Ruby program that prints “Hello, World!”.

Ruby Program:

# Ruby program to print "Hello, World!"
puts "Hello, World!"

Explanation of Code

1. puts:
   • This is a method used to print a string or other values to the console. In this case, we use it to output the text “Hello, World!”.
   • The puts method automatically adds a new line after printing, so the next output would start on a new line.
2. "Hello, World!":
   • This is the string to be displayed. Strings in Ruby are enclosed in double quotes ("), and in this case, the string is “Hello, World!”.

Output:

When the program runs, the console will display:

Hello, World!

Conclusion:

This simple Ruby program introduces the core concept of outputting text using the puts method. It’s a great starting point for beginners to get familiar with Ruby’s syntax and functionality. From this foundation, you can explore more advanced features of Ruby such as loops, conditionals, and object-oriented programming.
