+类型strcut1在定义它的包pack1中必须是唯一的，它的完全类型名是：`pack1.struct1`。
+
+下面的例子[Listing 10.2—person.go](examples/person.go)显示了一个结构体Person，一个方法，方法有一个类型为*Person的参数（因此对象本身是可以被改变的），以及三种不同的调用这个方法的方式：
+
+```go
+package main
+import (
+    "fmt"
+    "strings"
+)
+
+type Person struct {
+    firstName   string
+    lastName    string
+}
+
+func upPerson(p *Person) {
+    p.firstName = strings.ToUpper(p.firstName)
+    p.lastName = strings.ToUpper(p.lastName)
+}
+
+func main() {
+    // 1-struct as a value type:
+    var pers1 Person
+    pers1.firstName = "Chris"
+    pers1.lastName = "Woodward"
+    upPerson(&pers1)
+    fmt.Printf("The name of the person is %s %s\n", pers1.firstName, pers1.lastName)
+
+    // 2—struct as a pointer:
+    pers2 := new(Person)
+    pers2.firstName = "Chris"
+    pers2.lastName = "Woodward"
+    (*pers2).lastName = "Woodward"  // 这是合法的
+    upPerson(pers2)
+    fmt.Printf("The name of the person is %s %s\n", pers2.firstName, pers2.lastName)
+
+    // 3—struct as a literal:
+    pers3 := &Person{“Chris”,“Woodward”}
+    upPerson(pers3)
+    fmt.Printf(“The name of the person is %s %s\n”, pers3.firstName, pers3.lastName)
+}
+```
+
+第2种情况
+
+输出：
+
+    The name of the person is CHRIS WOODWARD
+    The name of the person is CHRIS WOODWARD
+    The name of the person is CHRIS WOODWARD
+
