CC: ABC instead of C: ABC, which is caused by indirectly obtaining the function address due to virtual. Similarly, for (A *) cc)-> ABC (); and (A *) bb)-> ABC ();, CC :: ABC and BB: ABC. However, note that (pC-> * (pC-> pF [0]) (); In, the pC type is C, the CC: ABC returned by pC-> pF [0] is of the void (CC:) () type. How can I perform implicit type conversion for the instance in the above example? If you do not perform this operation, the operation will be incorrect. As mentioned above, the
