emplace 当调用push或insert成员函数时, 我们将元素类型的对象传递给它们, 这些对象被拷贝到容器中. 而当我们调用一个emplace成员函数时, 则是将参数传递给元素类型的构造函数. emplace成员使用这些参数在容器管理的内存空间中直接构造元素.9.2.2. resize/reserve resize: 改变容器内含有元素的数量. reserve: 改变容器...

它实际上是一个函数,使用它的参数创建并返回一个back_insert_iterator对象。通过使用其参数(data)的类型(std::vector<int>),back_inserter()可以创建正确类型的back_insert_iterator对象。这种复杂性的结果是,你需要记住什么是函数,什么是类型。 标准库包含了太多的函数,这里就不再赘述了。只是为了体验一下什么是...
