Is the virtual function table created at runtime or during compilation in polymorphism? A: The virtual function table is determined during compilation, and the virtual function pointer vptr of class objects is determined in the runtime stage, which is the key to realizing polymorphism. (The call of a class function is not determined at compilation, but determined at runtime, when writing code, you cannot
