P.name = "Astaxie" // 赋值"Astaxie"给P的name属性.
P.age = 25 // 赋值"25"给变量P的age属性
fmt.Printf("The person's name is %s", P.name) // 访问P的name属性.
除了上面这种P的声明使用之外，还有两种声明使用方式
除了上面这种P的声明使用之外，还有另外几种声明使用方式：

- 1.按照顺序提供初始化值

P := person{"Tom", 25}
P := person{"Tom", 25}

- 2.通过`field:value`的方式初始化，这样可以任意顺序

P := person{age:24, name:"Tom"}

- 3.当然也可以通过`new`函数分配一个指针，此处P的类型为*person

P := new(person)

下面我们看一个完整的使用struct的例子

package main
