查看for循环计数器是否已增加 [英] See if a for loop's counter has increased

问题描述

我有一个for循环，我有一个if语句，将检查计数器是否增加。我该怎么检查？



下面我举了一个例子，说明了我的想法。感谢您提前的帮助。



我尝试过：

 for（int i = 0; i< 8; i ++）{
 if（** counter'i'has ** **）{
 // do stuff 
} 
} 

解决方案

在循环外添加变量，并将其设置为零。

在循环内部，将其与 i 的当前值进行比较。如果不同， i 已更改。

在循环的底部，将其设置为 i

I have a for loop and I have an if statement that will check if the counter increases. How would I check that?

Below I have given an example of what I had in mind. Thanks for your help in advance.

What I have tried:

for (int i = 0; i < 8; i++){
   if ( **counter 'i' has increased** ){
      //do stuff
   }
}

解决方案

Add a variable outside the loop, and set it ti zero.
Inside the loop, compare it to the current value of i. If it is different, i has changed.
At the bottom of the loop, set it to i
