Learn the basics of Ruby with hands-on practice.

Become a Ruby Professional

Do you want to be an interpreted language geek? Are you tired of getting entangled in the dense syntaxes? Does it irritate you to compile your code to machine language first? Are you looking for an easy-to-use scripting language? Well, Ruby is the best pick for you then!
This introductory module will be providing you with hands-on practice with the support of a bunch of interactive illustrations, exercises, and the integral topics of variables, built-in classes, objects, conditionals, blocks, and much more!

Learn Ruby from Scratch

## Problem statement

Define two classes, `Student` and `Teacher`, by including a module called `Formatter` in both classes.

### Task 1:

You're required to:

- Populate the class attributes of `Student` and `Teacher` through the `initialize()` method.

* Define attribute readers for these attributes.

Each of these classes has the attributes:

- `first_name` 
- `last_name` 
- `phone_no` 

And an instance method:

- `print_info`: This method uses the methods defined in the `Formatter` module to print the name and phone number information. 

### Task 2

The `Formatter` module includes the following methods:

* `format_name`: This method capitalizes only the first letters of `first_name` and `last_name` and combines the two.

* `format_phone`: This method takes a phone number stored as a string and removes its hyphens.
