# Darts
|

|

|
Welcome to Darts on Exercism's C Track. If you need help running the tests or
|
||
|
|
submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Write a function that returns the earned points in a single toss of a Darts game.
|
||
|
|
|
||
|
|
[Darts][darts] is a game where players throw darts at a [target][darts-target].
|
||
|
|
|
||
|
|
In our particular instance of the game, the target rewards 4 different amounts of points, depending on where the dart lands:
|
||
|
|
|
||
|
|
- If the dart lands outside the target, player earns no points (0 points).
|
||
|
|
- If the dart lands in the outer circle of the target, player earns 1 point.
|
||
|
|
- If the dart lands in the middle circle of the target, player earns 5 points.
|
||
|
|
- If the dart lands in the inner circle of the target, player earns 10 points.
|
||
|
|
|
||
|
|
The outer circle has a radius of 10 units (this is equivalent to the total radius for the entire target), the middle circle a radius of 5 units, and the inner circle a radius of 1.
|
||
|
|
Of course, they are all centered at the same point — that is, the circles are [concentric][] defined by the coordinates (0, 0).
|
||
|
|
|
||
|
|
Write a function that given a point in the target (defined by its [Cartesian coordinates][cartesian-coordinates] `x` and `y`, where `x` and `y` are [real][real-numbers]), returns the correct amount earned by a dart landing at that point.
