Today I'll see 《21 Tian Xue Tong C++》, See hidden base class methods , The brain suddenly broke , Confused , What's this for ？ Why hide base classes ？ Suddenly a little anxious , Now figure out this point, but how much can you remember without practicing for three days , And sometimes it's one-sided to just look at an author's exposition , The author feels that easy to understand examples do not apply to everyone's way of thinking , Finally, we should continue to look for information and make clear the knowledge points . I have been immersed in books before , Follow the ideas of books , In the end, the progress and efficiency are not up to expectations , So I'm going to change my thinking .C++ There is probably basic grammar 、 Classes and objects 、 Inheritance and derivation 、 Polymorphism and virtual functions 、 Heavy load and other key knowledge . In these two days, I'll find the information again to break through the remaining points I don't understand , Let's refer to books as dictionaries , Focus on the understanding of concepts 、 The reasons causing 、 Role and application scenarios , Find some simple examples to realize . After understanding the big framework, get familiar with the details later when reading the source code or writing the project , It should be too late .

Look at the points related to inheritance and derivation , I originally wanted to sort out the concepts and ideas , Picking up the pen, I found that the closed book seemed a little difficult to explain , Maybe this one is not very clear in my mind , Just review it again tomorrow and do it again .
