[Go] Creating a Point class.

package main

import (
    "log"
)

type Point struct {
    X float64
    Y float64
}

// function as constructor
func NewPoint(x float64, y float64) *Point {
    p := new(Point)

    p.X = x
    p.Y = y

    return p
}

func main() {
    p := NewPoint(3, 4)

    if !(p.X == 3.0) {
        log.Fatal("Wrong value")
    }

    if !(p.Y == 4.0) {
        log.Fatal("Wrong value")
    }
}
