Ruby Tutorial for Beginners!

Ruby

Hello! I'm rather new to this section of the forum and I've decided to start off my reputation on a good track!

So, here is my beginning tutorial to Ruby!

First we will write a hello world program which is the easiest thing to write in Ruby, in my opinion anyway.

Code:

print "Hello, World!"

The

Code:

print

command displays whatever is in between the

Code:

""

.

Pretty easy right? How about we add something more interesting.

Variables

In this section, I will teach you how to set and call variables in the easiest manner. Remember I will not make this a more challenging guide this guide is simply for the very beginning of Ruby.

Code:

print "Hello, what is your name?"
name = gets.chomp

print "Hello, #{name}."

So if you haven't already noticed, the program asks you for your name and says hello to you calling you by your name you typed into the console.

The

Code:

name = gets

basically assigns the variable

Code:

name

to whatever the user inputs.

The

Code:

.chomp

command eliminates random spaces which could screw up your beautiful formatting ;)

Okay, now this is where Ruby starts to look less like English.

The

Code:

#{ }

basically calls upon the variable that you specify in the middle.

If you typed out the code properly the code should output this

Code:

Hello, what is your name?Julian
Hello, Julian.

Thanks for reading! Hopefully more tutorials to come!
