用于添加元素到容器 c 尾端的 std::back_insert_iterator 。... backinserter函数用法 back_inserter()定义在头文件<iterator>中。接受一个指向容器的引用,返回一个与该容器绑定的插入迭代器,通过迭代器赋值会调用pushback添加元素到容器。 举例:... C++规范:std:copy() std::back_inserter() ...
constexprstd::front_insert_iterator<Container>front_inserter(Container&c); (C++20 起) front_inserter是为类型从参数类型推导的容器c构造std::front_insert_iterator的便利函数模板。 参数 c-支持push_front操作的容器 返回值 能用于添加元素到容器c起始的std::front_insert_iterator ...
copy(other.begin(), other.end(), back_inserter(coll.begin())); 我们用了一个东西叫做back_inserter,它是一种插入迭代器(后面你会看到,它实际是个函数),那么插入迭代器是什么? 我们知道,迭代器用来实现容器操作的一种抽象,有了迭代器,那么我们遍历所有容器,采用的几乎都是同一种方式,换句话说,迭代器帮我...
C ++ 插入迭代器 2016-08-30 21:59 −C++ 语言提供了三种插入器,其差别在于插入元素的位置不同。 (1)back_inserter,创建一个使用push_back 实现插入的迭代器。 (2)front_inserter,创建一个使用push_front实现的插入迭代器。 (3)inserter,使用insert实现的插入,此... ...
