void* A::operator new(size_t size) { cout<<"Our operator new..."); return ::operator new(size); } 这里的operator new调用了全局的new来进行内存分配(::operator new(size))。当然这里的全局new也是可以重载的,但是在全局空间中重载void * operator new(size_t size)函数将会改变所有默认的...

I believe it just move the "removed" elements to after the new end of range. To actually physically remove them depend on your data structure. If you use list or vector you can use the list.erase(), vector.erase() member function for the actual physical removal. ...
