赋值运算符

def main(args: Array[String]): Unit = {

  var a =1
  a +=2
  println(a)
  a-=3
  println(a)
  a*=3
  println(a)
  a /=4
  println(a)
  a%=5
  println(a)

}

位运算

  def main(args: Array[String]): Unit = {
    println(5&4)//4
    println(5|4)//5
    println(4<<2)//16
    println(4>>2)//1
    ```
 val result=10-2+3*4/2
  println(result)
  val a=true
  val b=false
  val c=false
  println(a||b&&c)

}

}
