Hello CodeNewbies!

Welcome back to the CodeNewbie Challenge! It is January and perhaps you have made a coding resolution, or you are just looking to improve your skills.

Whatever your next step, I hope that you are ready to start working on some CodeNewbie Challenges.

Hello CodeNewbies

This challenge will be to write a program that says hello. The program may be written in the language of your choice. As always, the challenge is split into three levels.  Please choose your level based on your available time and your comfort level with the challenge.

A note about specifications

Each level will contain one or more specifications. These specifications describe the level in a structured way. Each specification will have three parts starting with ‘given’, ‘when’, and  ‘then’. Each of those parts has a specific purpose.

Given - This is where setup goes; it says what is expected to already exist.

When - Change happens here; this describes the action that is taken.

Then - Describes the results of the change.

Level 1

For this level, write a program that will print “Hello CodeNewbies!” to the screen when it is run.

Specification

Given your program

When the program is run

Then it will say “Hello CodeNewbies!”

Level 2

There are lots of great languages to learn including Ruby, Python, and Javascript. For this level, make your program say hello to the language it’s written in and also to CodeNewbies.

Specification

Given a program written in Python

When the program is run

Then it will say “Hello Python!”

and it will say “Hello CodeNewbies!”

Level 3

Now, let’s make a program that will take zero or more languages and say hello to them, and then say hello to CodeNewbies.

Specification

Given a level 3 program

When it is run with “Ruby” and “Javascript”

Then it will say “Hello Ruby!”

and it will say “Hello Javascript!”

and it will say “Hello CodeNewbies!”


Given a level 3 program

When it is run without any languages

Then it will say “Hello CodeNewbies!”

More Information

This challenge is based on one of the classic ways to begin programming in a language, generally known as “Hello World”. The Hello World exercise is a great way to get started learning.

Here is a listing of the Hello World exercise in over 200 languages.

The specification format comes from acceptance testing and behavior driven development.

Thank You For Your Participation

I hope that you enjoyed this challenge.  If you are looking for additional CodeNewbie Challenges there is a list available on CodeNewbie Discourse.
