Golang : Random integer with rand.Seed() within a given range




Need to generate a random single integer within a given number range. For example, get one random integer from 1 to 10. The Golang code to do this : package main import ( "fmt" "math/rand" "time" ) func numRand(min, max int) int { rand.Seed(time.Now().UTC().UnixNano()) return rand.Intn(max-min) + min } func main() { num := numRand(1, 10) fmt.Println("Number is : ", num) } NOTE : Executing this code in play.golang.org WILL NOT work. Sample output : Number is : 9 Number is : 4 Number is : 5 Number is : 1
