allocator就是用来分配内存的,最重要的两个函数是allocate和deallocate,就是用来申请内存和回收内存的,外部(一般指容器)调用的时候只需要知道这些就够了。内部实现,目前的所有编译器都是直接调用的::operator new和::operator delete,说白了就是和直接使用new运算符的效果是一样的,所以老师说它们都没做任何特殊处理。

static assertion failed: std::map must have the same value_type as its allocator 这意味着std::map使用的分配器的value_type与std::map本身的value_type不匹配。在std::map中,value_type通常是一个std::pair<const Key, T>,其中Key是键的类型,T是值的类型。如果分配器的value_type不是这种类...
