Read and Write Fibonacci series to Channel in Golang

The main function has two unbuffered channels ch and quit. Inside fibonacci function the select statement blocks until one of its cases is ready.

Example

package main

import (
	"fmt"
)

func fibonacci(ch chan int, quit chan bool) {
	x, y := 0, 1
	for {
		select {
		case ch <- x: // write to channel ch
			x, y = y, x+y
		case <-quit:
			fmt.Println("quit")
			return
		}
	}
}

func main() {
	ch := make(chan int)
	quit := make(chan bool)
	n := 10

	go func(n int) {
		for i := 0; i < n; i++ {
			fmt.Println(<-ch) // read from channel ch
		}
		quit <- false
	}(n)

	fibonacci(ch, quit)
}
