Fix the Method
This code has a Circle struct with an area method, but the method is broken — it's missing &self so it can't access the circle's fields!
Fix the code so it prints:
text
Area: 78.5
Hint: Methods need &self as their first parameter so they can read the struct's fields.
rust
struct Circle {
radius: f64,
}
impl Circle {
fn area() -> f64 {
self.radius * self.radius * 3.14
}
}
fn main() {
let c = Circle { radius: 5.0 };
println!("Area: {}", c.area());
}
