Go語言中for迴圈的幾種用法

 1 package main
 2 
 3 //在go語言裡面 就一種迴圈 那就是for
 4 func main() {
 5 
 6     var a []int = []int {9,8,7,6,5,4,3,2,1}
 7 
 8     println("-------------Test1--------------")

10         println("index is ",i," number is ", a[i])
11     }

13     println("-------------Test2--------------")
 
14     for i := 0; i <= 10 ;i++ {
15         if i % 2 ==0 {
16             println(i)
17         } else {
18             println(2 * i)
19         }
20     }

38     //我驚了 這種寫法代替while
