package main

import "fmt"

type Person struct {
	Name string
}

func main() {
	p := Person{Name: "Bob"}  
	pp := &Person{Name: "Big Bob"}
	ppp := new(Person)
	mapMake := make(map[int]int, 10)
	mapNew := new(map[int]int)
	fmt.Println(p, pp, ppp, mapMake, mapNew)
}

最终会打印出

1

{Bob} &{Big Bob} &{} map[] &map[]
