Golang : Roll the dice example

Just a simple example on how to simulate dice rolling. Useful in situation where you need to use random single digit number to ensure different results very time.

Here you go!

 package main

 import (
 "fmt"
 "math/rand"
 "time"
 )

 func rollDice() int {

 // prepare the dice
 dice := []int{1, 2, 3, 4, 5, 6}
 rand.Seed(time.Now().UnixNano())

 return dice[rand.Intn(len(dice)-1)]
 }

 func main() {
 dice1 := rollDice()
 dice2 := rollDice()
 dice3 := rollDice()

 fmt.Println("Dice 1: ", dice1)
 fmt.Println("Dice 2: ", dice2)
 fmt.Println("Dice 3: ", dice3)
 }

Sample output:

Dice 1: 2

Dice 2: 2

Dice 3: 2

Dice 1: 5

Dice 2: 1

Dice 3: 3

Happy coding!
