std::vector<int, std::allocator<int>>

stdvector<int, std::allocator<int>>是一个使用标准库默认内存分配器std::allocator的容器。std::allocator是标准库容器的默认内存分配器，用于在运行时分配和释放内存。它使用new和delete表达式来进行内存的分配和释放。在C++中，使用std::allocator来创建和管理动态内存是一种常见的做法。现代C++程序也可以使用智能指针类型，如shared_ptr、unique_ptr和weak_ptr，来更安全地管理动态内存，确保在没有用户使用它时自动释放内存。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
