我应该优先于const_iterators的迭代器吗？ [英] Should I prefer iterators over const_iterators?

问题描述

最近有人在提出了来自Scott Meyers的文章：

Someone here recently brought up the article from Scott Meyers that says:

• 首选迭代器 over const_iterators （ pdf链接）。

• Prefer iterators over const_iterators (pdf link).

有人评论说这篇文章可能已过时。我想知道你的意见是什么？

Someone else was commenting that the article is probably outdated. I'm wondering what your opinions are?

这里是我的：文章的要点之一是你不能删除或插入 const_iterator ，但我认为使用它作为 const_iterators 的参数很有趣。我认为整个点 const_iterators 它，你根本不修改范围，元素本身通过替换它们的值和范围通过插入或删除。

Here is mine: One of the main points of the article is that you cannot erase or insert on a const_iterator, but I think it's funny to use that as an argument against const_iterators. I thought the whole point of const_iterators it that you do not modify the range at all, neither the elements themselves by substituting their values nor the range by inserting or erasing. Or am I missing something?

推荐答案

我完全同意你的看法。
我想答案很简单：
使用const_iterators，其中const值是正确的使用，反之亦然。
对我来说，那些反对const_iterators的人一定是反对const的...

I totally agree with you. I think the answer is simple: Use const_iterators where const values are the right thing to use, and vice versa. Seems to me that those who are against const_iterators must be against const in general...
