Golang Exercise to practice structs, interfaces, and methods

gokata.go

package main

import (
	"fmt"
	"math"
)

type cube struct {
	length float64
}

type box struct {
	length float64
	width  float64
	height float64
}

type sphere struct {
	radius float64
}

type ofStructure interface {
	volume() float64
}

func (c cube) volume() float64 {
	return c.length * c.length * c.length
}

func (s sphere) volume() float64 {
	return (4 * math.Pi * math.Pow(s.radius, float64(3))) / 3
}

func (b box) volume() float64 {
	return b.length * b.width * b.height
}

func calculateVolume(kind ofStructure, called string) {
	fmt.Printf("The Volume calculated for our %s is: %f \n", called, kind.volume())
}

func main() {

	c := cube{
		length: 7,
	}

	b := box{
		length: 5.5,
		width:  5.5,
		height: 7.7,
	}

	s := sphere{
		radius: 7.14,
	}

	calculateVolume(c, "Cube")
	calculateVolume(b, "Box")
	calculateVolume(s, "Sphere")
}

Hey thank you for sharing this. Was having difficulty understanding interfaces

Hey, I'm glad I could assist you with your journey🙏🏾
