//swift函数的使用

//countPerson("john","harry","byte");

func changeName(inout name:String){

name+="AAA"

}

//var myname="barry"

//

//changeName(&myname)

//

//println(myname)

func addMoney(a:Int,b:Int)->Int{

}

//

//var getMoney:(Int,Int)->Int=addMoney

//

//var num=getMoney(1,2)

//println(num)

func onMoneyAdded((Int,Int)->Int){

onMoneyAdded(addMoney)
