now only one bat entity that can be converted to animal.Virtual inheritance is applied to mammal and wingedanimal to create a virtual table (vtable) pointer ("Vpointer") because the mammal instance's start address and the memory offset of its animal portion are not clear until the program runs allocated memory. So "Bat" contains vpointer, mammal, Vpointer, Wingedanimal, Bat, Animal. There are two virtual table pointers, where the object address of the most derived class points to the virtual ta

For example, an iphone's gross margin of about 60%, a genuine LV bag is dozens of times times the gross profit of a goods. The pricing style of this era has changed, let's call it "experiential pricing".
