circle
Instructions
Create the structures Circle
and Point
. You'll need to create the necessary methods for the code in the usage to compile, and give the expected output.
Methods:
Point
:distance()
-> returns the distance between two coordinates.
Circle
:diameter()
-> returns the diameter of the circle.area()
-> returns the area of the circle.intersect()
-> which returnstrue
, if 2 circles intersect.
Associated Functions
Circle
:new()
-> receives three 64bit floating point numbers in the following order: x, y and radius (x and y are the coordinates of the center of the new circle). The function returns a new circle.
Expected Functions and Structures
This snippets are incomplete, you'll need to complete them. You'll find some useful information in the usage.
#[derive(Debug)]
pub struct Circle {
pub center //..
pub radius //..
}
impl Circle {
// ...
}
#[derive(Debug)]
pub struct Point {
// ...
}
impl Point {
// ...
}
Usage
Here is a program to test your function
use std::f64::consts;
use circle::{Circle, Point};
fn main() {
let circle = Circle::new(500.0, 500.0, 150.0);
let circle1 = Circle {
center: Point { x: 80.0, y: 115.0 },
radius: 30.0,
};
let point_a = Point { x: 1.0, y: 1.0 };
let point_b = Point { x: 0.0, y: 0.0 };
println!("circle = {:?} area = {}", circle, circle.area());
println!("circle = {:?} diameter = {}", circle, circle.diameter());
println!("circle1 = {:?} diameter = {}", circle1, circle1.diameter());
println!(
"circle and circle1 intersect = {}",
circle.intersect(&circle1)
);
println!(
"distance between {:?} and {:?} is {}",
point_a,
point_b,
point_a.distance(&point_b)
);
}
And its output
$ cargo run
circle = Circle { center: Point { x: 500.0, y: 500.0 }, radius: 150.0 } area = 70685.83470577035
circle = Circle { center: Point { x: 500.0, y: 500.0 }, radius: 150.0 } diameter = 300
circle1 = Circle { center: Point { x: 80.0, y: 115.0 }, radius: 30.0 } diameter = 60
circle and circle1 intersect = false
distance between Point { x: 1.0, y: 1.0 } and Point { x: 0.0, y: 0.0 } is 1.4142135623730951
