This lesson is mainly about demonstrating the various experimental procedures.Say a few feelingsThe ideas are great!I think we are all very good ... For example, Wwx game, using the game engine ... It's said that LTP's team also used the game engine.

The knowledge of C # type conversion is a big catch in every book and blog post. So why do I have to repeat these words----only because they are described in various articles is very good, clear, but in the actual use (writing code) has been ignored.

What is encapsulation?encapsulation is the collection of data or functions in a unit (what we call a Class). Encapsulated objects are often referred to as abstract data types.  What is the meaning of using encapsulation?The meaning of encapsulation

1. What is polymorphicAnother important concept in object-oriented programming is polymorphism. At run time, you can invoke methods in the derived class by pointing to a pointer to the base class. You can put a set of objects in an array, and then
