3.在第13行,选用了一个叫做count_if()的算法来处理容器vi。这个算法的作用是对vi中满足一定条件的元素进行计数。 4.count_if()的参数分别是指向容器开头的迭代器(泛化指针)、指向容器结尾的迭代器以及对元素的过滤条件。vi.begin()返回的是指向开头的迭代器,vi.end()返回的是指向结尾的迭代器。 5.less<int>...

First, the sizes are compared (size). For every group of equivalent values (such as those returned byequal_range): sizes are compared (count). all possible permutations of each group are compared (permutation). Note that theunordered_multiset::hash_functionandunordered_multiset::key_eqobjects ...
Complexity Constant. Iterator validity All iterators, pointers and references remain valid, but now are referring to elements in the other container, and iterate in it. non-member overloads: operators (unordered_multiset) swap (unordered_multiset)...
