定义函数，小括号里面是参数

func saylovetosb (name string,num int){       for i := 1; i <= num; i++ {        fmt.Printf("我爱%s\n",name)    }}func main() {      saylovetosb("拉芳",10)}

 

不定长参数  必须要放在参数的末尾

func saylovetosb2(names ...string)  {    fmt.Printf("我爱%s\n",names)}func main() {    saylovetosb2("拉芳","拉草","拉潘婷")}

执行结果

 

多个参数，类型相同可以合并

 

//func saylovetosb2(name  string,name2 string,num int)  { 可以合并为下面的写法func saylovetosb2(name  ,name2 string,num int)  {    fmt.Printf("我爱%s\n",)}func main() {    saylovetosb2("拉芳","拉草","拉潘婷")}
