01-warmup

package main

import "fmt"

func main() {
	type item struct {
		id    int
		name  string
		price int
	}

	type game struct {
		item  // （1）此处的item既是类型，也是字段
		genre string
	}

	games := []game{  // （2）最前面的item和genre可以删除，打印的时候自己一开始用了类似g.item.name这种（两种打印都可以）；三个大括号
		{
			item:  item{id: 1, name: "god of war", price: 50},
			genre: "action adventure",
		},
		{item: item{id: 2, name: "x-com 2", price: 40}, genre: "strategy"},
		{item: item{id: 3, name: "minecraft", price: 20}, genre: "sandbox"},
	}

	fmt.Printf("Inanc's game store has %d games.\n\n", len(games))

	for _, g := range games {
		fmt.Printf("#%d: %-15q %-20s $%d\n",
			g.id, g.name, "("+g.genre+")", g.price)  // （3）%-15q %-20s
	}
}

这是我写的

import "fmt"

func main() {
	
type item struct {
	id int
	name string
	price int
}

type game struct {
	item
	genre string
}

games := []game{
	{item: item{id: 1, name: "god of war", price: 50}, genre: "action adventure"},
	{item: item{id: 2, name: "x-com 2", price: 30}, genre: "strategy"},
	{item: item{id: 3, name: "minecraft", price: 20}, genre: "sandbox"},
}

for _, g := range games {
	fmt.Printf("%d %#v %d %s\n", g.id, g.name, g.price, g.genre)
}

}
