Show 例子 1

尝试以下示例程序以了解Scala编程语言中可用的所有算术运算符。

例子 (Example)

object Demo {
   def main(args: Array[String]) {
      var a = 10;
      var b = 20;
      var c = 25;
      var d = 25;
      println("a + b = " + (a + b) );
      println("a - b = " + (a - b) );
      println("a * b = " + (a * b) );
      println("b/a = " + (b/a) );
      println("b % a = " + (b % a) );
      println("c % a = " + (c % a) );
   }
}

将上述程序保存在Demo.scala 。 以下命令用于编译和执行此程序。

Command

\>scalac Demo.scala
\>scala Demo

输出 (Output)

a + b = 30
a - b = -10
a * b = 200
b/a = 2
b % a = 0
c % a = 5
