[v3] Implement new Concept Exercise: basics

[wolf99]

This issue describes how to implement the <SLUG> concept exercise for the track.

Getting started

Please please please read the docs before starting. Posting PRs without reading these docs will be a lot more frustrating for you during the review cycle, and exhaust Exercism's maintainers' time. So, before diving into the implementation, please read up on the following documents:

• The features of v3.
• Rationale for v3.
• What are concept exercise and how they are structured?

Please also watch the following video:

• The Anatomy of a Concept Exercise.

Goal

The goal of this exercise is to teach the student basic concepts of the C++ language.

Learning objectives

• Know what a variable is.
• Know how to define a variable.
• Know how to update a variable.
• Know how to use type inference for variables.
• Know how to define a function.
• Know how to return a value from a function.
• Know how to call a function.
• Know about the static modifier.
• Know how to define an integer.
• Know how to use mathematical operators on integers.
• Know how to define single- and multiline comments.

Out of scope

• Naming rules for identifiers.
• Memory and performance characteristics
• Preprocessor defines

@wolf99 can start working on some concepts?

Hi @kana800
Please do!
This is the first concept exercise Basics.
Maybe take a look at the other language tracks to see how they have created such a concept exercise.
