Virtual Tables

What is Virtual Tables?
Virtual tables (vtables) are compiler-generated lookup tables used in C++ to implement dynamic polymorphism, especially with virtual functions. Each class that declares or inherits virtual functions has a vtable, which contains pointers to the most derived versions of those virtual functions for that class. When a virtual function is called through a pointer or reference to a base class, the vtable is consulted at runtime to determine the actual function to execute based on the object's dynamic type.
