Go中的for循环中有多个变量 [英] Multiple variables in for loop in Go

问题描述

来自javascript世界，我想要达到这样的效果：

I am trying to write a for loop in Go with multiple variables.

p>

Coming from the javascript world, I'd like to achieve something like this:

    var i = 10;
    var b = 2;
    for (var a = b; i; i /= 2, b *= b ) {
      // some code
    }

我试过了这样的'原始翻译'：

I've tried a 'raw translation' like this:

   i, b := 10, 2
   for a := b; i; i /= 2, b *= b {
      // some code
    }

<但它不起作用。什么是正确的语法？

But it doesn't work. What is the proper syntax?

非常感谢！

推荐答案

去吧，你可以像循环一样在循环中进行多变量赋值。 （

$ b

In Go, you can do multiple variable assignment in a loop like so.

package main

func main() {
    var (
        i = 10
        b = 2
    )
    for a := b; i != 0; i, b = i/2, b*b {
      // some code
    }
}
