循环

object Base13 {
  def main(args: Array[String]): Unit = {
    var i = 1;
    while(i<3001){
      println(s"$i, I miss you!")
     i = i + 1
    }
  }
}

1~100内的奇数

object Base14 {
  def main(args: Array[String]): Unit = {
   //var i = 1
    //while(i <=100 ){
    //  println(i)
    //  i += 2
   var i = 1
    while(i <=100 ){
      if(i%2 == 1)
      println(i)
      i += 1
    }
  }
}

求1~100的和

object Base15 {
  def main(args: Array[String]): Unit = {
    var sum = 0
    var i = 1
    while(i <= 100) {
      sum += i
      i += 1
    }
      println(sum)
  }
}

object Base18 {
  def main(args: Array[String]): Unit = {
    var i = 100
    do{
      println(i)
      i = i + 1
    }while(i <= 10)
    println("欢迎下次使用!")
  }
}
