做while循环检查最后一次迭代 [英] Do while loop check for last iteration

问题描述

这听起来像是一个基本问题，但我想检查一下我的思维过程是否正确.

This may sound like an elementary question, but I want to check whether my thought process is correct.

我有一个do while循环，我想检查循环何时进入上一次迭代，以便设置一个值或不设置一个值.我已经提供了这种解决方案，但没有感觉，我想知道是否还有另一种方法.

I have a do while loop and I want to check when the loop has entered the last iteration so as to either set a value or not. I have come with this sort solution but doesn't feel and I was wondering whether there is a another way.

 do 
  { 
      int iterationCheck ++;

      if( iterationCheck! = counter)
       // Do something 
       counter++;
   } while (true)

这是正确的还是有更好的方法?

Is this correct or is there a better way?

推荐答案

确定您可以执行此操作以计算迭代次数但是，请将"interationCheck = 0"变量声明放在do/while范围之前.

Sure you could do this to count the iteration But put the 'int iterationCheck=0' variable declaration before the do/while scope.

您也可以进行"for"循环(那会更好)

You could go for a 'for' loop too ( which would be better )

但是，这一切都取决于循环的条件.因为我们无法推断出循环的退出"状态，所以我们无法提供准确的答案.

However it all depends on the condition of your loop. Because we can't infer the 'out' condition of your loop so we can't provide a accurate answer.
