测试go语言函数和结构体

测试下函数，可以返回多个值：

报错sum变量声明了没使用。修改下改成下划线

Go 复制代码

package main
import "fmt"



func main() {
  _, str := add(9526, 1)
  fmt.Println(str)
}

func add(a,b int)(c int, str string) {
  c = a + b
  str = fmt.Sprintf("%d + %d = %d", a, b, c)
  return
}

打印：

ok.

再测试下结构体：

Go 复制代码

package main
import "fmt"



func main() {
  testStruct()
}

type Person struct {
    name string
    nickName string
    wugong string
}

func testStruct() {
  var guojing Person
  guojing.name = "郭靖"
  guojing.nickName = "靖哥哥"
  guojing.wugong = "降龙十八掌"
  
  // new创建指针
  duanzhengchun := new(Person)
  duanzhengchun.name = "段正淳"
  duanzhengchun.nickName = "段郎"
  duanzhengchun.wugong = "一阳指"
  
  zhouzhiruo := &Person{}  // 创建实例并取地址，返回指针
  zhouzhiruo.name = "周芷若"
  zhouzhiruo.nickName = "周芷若"
  zhouzhiruo.wugong = "九阴真经"
  
  laoma := Person{
    "马老师",
    "老马",
    "闪电五连鞭",
}
  
  fmt.Printf("我是%s, 我擅长%s\n", guojing.nickName, guojing.wugong)
  fmt.Printf("我是%s, 我擅长%s\n", duanzhengchun.nickName, duanzhengchun.wugong)
  fmt.Printf("我是%s, 我擅长%s\n", zhouzhiruo.nickName, zhouzhiruo.wugong)
  fmt.Printf("我是%s, 我擅长%s\n", laoma.nickName, laoma.wugong)
}

打印：

ok.
