Go语言学习笔记六--Go语言中for循环的几种用法

Go语言中for循环的几种用法

package main

//在go语言里面 就一种循环 那就是for
func main() {

    var a []int = []int {9,8,7,6,5,4,3,2,1}

    println("-------------Test1--------------")
    for i := range a{
        println("index is ",i," number is ", a[i])
    }

    println("-------------Test2--------------")
    for i := 0; i <= 10 ;i++ {
        if i % 2 ==0 {
            println(i)
        } else {
            println(2 * i)
        }
    }

    println("-------------Test3--------------")
    for i := 0; i <= 10 ;i++ {
        println(i)
        if i == 5 {
            break
        }
    }

    println("-------------Test4--------------")
    for i := 0; i <= 10 ;i++ {
        if i % 2 == 0 {
            continue
        }
        println(i)
    }

    //我惊了 这种写法代替while
    println("-------------Test5--------------")
    i := 0
    for i <= 10  {
        i++
        if i % 2 == 0 {
            continue
        }
        println(i)

    }

    //无线循环
    println("-------------Test6--------------")

    for {
        i++
        if i % 2 == 0 {
            continue
        }
        if i > 50 {
            break
        }
        println(i)
    }

}
