1回答 在std::vector中插入与在std::deque中插入 、、 对于buffer实现,我首先使用vector,然后尝试使用deque。当打印向量和队列的值时,我得到了不同的结果。代码如下:#include <vector> {for (std::vector<int>::iterator it = a_CircularBuffer.begi ...
usingvector=std::vector<T,std::pmr::polymorphic_allocator<T>>; } (2) (C++17 起) 1)std::vector是封装动态数组的序列容器。 2)std::pmr::vector是使用多态分配器的模板别名。 除了部分特化std::vector<bool>外,元素被连续存储,这意味着不仅可通过迭代器,还能用指向元素的常规指针访问元素。这意味着指...
