Timer的使用 引用（指针）的测试

<!-- lang: cpp -->
package main

import (
"fmt"
"time"
)

func panic_test(){
defer func() {
	fmt.Println("no")
//		if e := recover(); e != nil {
//			fmt.Println("some wrong:",e)
//		}
}()
z := 0
zero := 1/z
fmt.Println(zero)
}
func main() {
panic_test()
go func() {
	for a := range time.Tick(1e9) {
		fmt.Printf("cur conn num: %vn",a)
	}
}()

list := []string{"a","b","c","d"}
//fmt.Printf("in main,list addr is %p rn",list)

go func( list []string)	{
	//fmt.Printf("in goruotine,list)
	time.Sleep(1e9)
	(list)[2] = "CC"
	list = append(list,"FF")
	for i,c := range list{
		fmt.Println( "in go",i,c)
	}
}(list)

for i,c := range list{
	fmt.Println( i,c)
	time.Sleep(1e9)
}

fmt.Println( "second printf")
for i,c)
	//time.Sleep(1e9)
}
for{time.Sleep(1e5)}
}
