用向量除以向量中的所有元素

本文介绍了用向量除以向量中的所有元素的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

亲爱的， 我想知道我是否可以将该向量的所有元素除以该向量的最大值 元素。 我检查了STL引用并找到了transform，for_each和最近 BOOST_FOREACH，但是transform和for_each算法不适合 因为我有另一个提供给函数的论据，即 max_element。我想知道这是否可行通过 标准。 BOOST_FOREACH对我来说似乎是最好的选择。但我想知道:) Rgds，

Dear all, I was wondering if I could divide all elements of a vector by the max element of that vector. I checked the STL references and found transform, for_each and lately BOOST_FOREACH, but transform and for_each algorithms are not suited since I have another argument to supply to the functions, namely max_element. I wondered if this is possible or not through the standard. BOOST_FOREACH seemed the best option to me. But I wondered :) Rgds,

写一个简单的for循环真的很难吗？它可能会比STL杂技更容易阅读。 也可能更短。

Is it really that hard to write a simple for-loop? It will probably be easier to read than the STL acrobatics needed to do the same thing. Probably shorter too.

你在那里，现在检查绑定家庭，例如 std :: bind2nd或强大的boost :: bind版本。 有些东西（未经检查！） std :: transform（v.begin（），v.end（），v.begin（）， std :: bind2nd（std :: divides< double> ;， std :: max_element（v.begin（），v.end（）））;

You are halfway there, now check the "bind" family, for example std::bind2nd or the powerful boost::bind versions. Something along the lines of (unchecked!) std::transform(v.begin(), v.end(), v.begin(), std::bind2nd(std::divides<double>, std::max_element(v.begin(), v.end()));
