不是本课的问题，自己实践遇到的问题

源自：6-3 switch语句的高级用法

var enemyLives = Int()

var damage = Int()

enemyLives = 15

damage = 3

var attackTimesVerify = enemyLives % damage

var attackTimes = enemyLives / damage

if attackTimesVerify == 0 {

println("\(attackTimes) attacks needed!")

} else {

attackTimes = attackTimes + 1

println("\(attackTimes) attacks needed!")

}

for var i = 1 ;i <= 5; i++ {

for enemyLives; enemyLives >= 0; enemyLives -= damage {

if enemyLives > 0 {

println("round" + "\(i)" + ": " + "\(enemyLives)hp left!")

} else {

println("you win")

}

控制台输出全部是“round1”，

怎么变成有序的“round1”“round2”“round3”…… ？
