int i vs int index等。哪一个更好？ [英] int i vs int index etc. Which one is better?

问题描述

可能的重复项：

是一个名为i的变量不可接受吗？

什么是循环变量的理想变量命名约定？

我一直使用 int i 用于通用循环变量。当然，在大的嵌套循环或其他复杂的东西，我可以使用一个描述性的名字，但你最喜欢看哪一个。

Coming from a C background I've always used int i for generic loop variables. Of course in big nested loops or other complex things I may use a descriptive name but which one had you rather see?

int i;
for(i=0;i<Controls.Count;i++){
  DoStuff(Controls[i]);
}

或

int index;
for(index=0;index<Controls.Count;index++){
  DoStuff(Controls[index]);
}

在当前项目中，我正在处理这两种样式和索引由 ndx 替换。

In the current project I am working on there are both of these styles and index being replaced by ndx.

哪一个更好？ i 变量太泛吗？还有其他C风格名称？ i，j，k 是否所有这些都被实际的描述性变量取代？

Which one is better? Is the i variable too generic? Also what about the other C style names? i, j, k Should all of these be replaced by actual descriptive variables?

推荐答案

i 在第一个循环中是非常标准的，其次是 j

i, however, is pretty standard in terms of the first loop, followed by j for an inner loop and k for an inner-inner loop, and so on.

与几乎所有的命名规则一样，对于内部循环， k 只要它是一个项目的标准，并为所有成员工作良好，那么很好。

As with almost all naming rules, as long as it is standard within a project, and works well for all members thereof, then it's fine.
