package main
import (
"fmt"
"runtime"
"sync"
)
var wg sync.WaitGroup
func alphabets() {
for char := 'a'; char < 'a'+26; char++ {
fmt.Printf("%c ", char)
}
wg.Done() //decrement number of goroutines to wait for
}
func numbers() {
for number := 1; number < 27; number++ {
fmt.Printf("%d ", number)
}
wg.Done()
}
func main() {
runtime.GOMAXPROCS(2)
wg.Add(2) //wait for two goroutines
fmt.Println("Starting Go Routines")
go alphabets()
go numbers()
fmt.Println("
Waiting To Finish")
wg.Wait() //wait for the two goroutines to finish executing
fmt.Println("
Terminating Program")
}
I expect the output to be mixed up(for lack of a better word), but instead; a sample output is:
$ go run parallel_prog.go
Starting Go Routines Waiting To Finish a b c d e f g h i j k l m n o p q r s t u v w x y z 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Terminating Program
What I'm I missing?
Thanks,
