Go 运算符


Go 运算符

运算符用于对变量和值执行操作。

例如,+ **运算符** 用于将两个值加在一起,如下例所示。

package main
import ("fmt")

func main() {
  var a = 15 + 25
  fmt.Println(a)
}

虽然 + 运算符通常用于将两个值加在一起,但它也可以用于将变量和值加在一起,或将变量和另一个变量加在一起。

示例

package main

    sum2 = sum1 + 250 // 400 (150 + 250)
    sum3 = sum2 + sum2 // 800 (400 + 400)
  )
  fmt.Println(sum3)
}
