[RUST/COMMON] struct 키워드 : 체질량 지수(Body Mass Index) 구하기

■ struct 키워드로 구조체를 사용해 체질량 지수(Body Mass Index)를 구하는 방법을 보여준다.

▶ 예제 코드 (RS)


struct Body
{
    weight : f64,
    height : f64
}

fn calculate_bmi(body : &Body) -> f64
{
    let height : f64 = body.height / 100.0;

    return body.weight / height.powf(2.0);
}

fn main()
{
    let person1: Body  = Body
    {
        weight : 80.0,
        height : 165.0
    };

    let person2: Body = Body
    {
        weight : 65.0,
        height : 170.0
    };

    println!("사람 1 = {:.1}", calculate_bmi(&person1));
    println!("사람 2 = {:.1}", calculate_bmi(&person2));
}

struct Body

{

weight : f64,

height : f64

}

fn calculate_bmi(body : &Body) -> f64

{

let height : f64 = body.height / 100.0;

return body.weight / height.powf(2.0);

}

fn main()

{

let person2: Body = Body

{

weight : 65.0,

height : 170.0

};

println!("사람 1 = {:.1}", calculate_bmi(&person1));

println!("사람 2 = {:.1}", calculate_bmi(&person2));

}
