方法1

/*普通用法*/

func main(){
    var count int = 5;
    var i int
    for i = 1;i <= count; i++{
        fmt.Println("This is ",i)
    }
}

方法2

/*缺省初始化*/

func main(){
    var count int = 5;
    var i int = 1
    for ;i <= count; i++{
        fmt.Println("This is ",i)
    }
}

方法3

/*缺省执行动作*/

func main(){
    var count int = 5;
    var i int = 1
    for i <= count{
        fmt.Println("This is ",i)
        i += 1
    }
}

方法4

/*条件恒true,相当于while(1)*/

func main(){
    var count int = 5
    var i int = 1
    for true{
        fmt.Println("This is ",i)
        i += 1
        if i ==  count +1 { 
            break 
        }
    }
}

方法5

/*什么都没有类型for(;;)*/
func main(){
    var count int = 5;
    var i int = 1
    for {
        fmt.Println("This is ",i)
        i++
        if i== count +1 {
            break
        }
    }
}

以上的运行结果均为:
