object-oriented design of the project, the practical experience of the project and the importance of programming ideas. 
Where construction and static to initialization parameters and mass participation for the beginner for me 
is indeed a very clever use of the method, 
I tried to use C ++ to write the procedures, but also truly appreciate the real differences in programming language, 
a lot of things use c ++ realize it is not easy to java, of course, is my understanding, and not enough 
for the C ++ programming ideas and skills to master is not in place, so I'm not finished yet. I will try to 
finish it in order to improve their understanding.
