1. What is polymorphism? Another important concept in Object-Oriented Programming is polymorphism. At runtime, you can call methods in the derived class by pointing to the base class pointer. Put a group of objects in an array and call their methods.

Why not read? I can't write comments after reading it. Only in the process of sorting and summarization can I know what are the points and which represent the essence of the author. It took me more than a week to finish finishing Scott Meyers's
