.4. Inheritance and polymorphism is a very tall place in C + +, a means of abstracting the real world.5.c++ is a very powerful language, can not only touch the bottom of the implementation, but also the use of object-oriented features, so that C + + different from other languages have the advantage of high security. Many backgrounds are written in the C + + language.Second: The Guide map of the module will be updated continuously, and the key content of this part will be explained.Above is I in

Beginners Java, learning a language is not only to learn its grammar, logical thinking ability, and every language has its own unique aspect, so there are so many languages to learn ah = =, so want to really learn the language, its compiler mechanism, the operating mechanism of how much also to dabble some ah. This is a beginner Java some of the mechanisms of understanding, if there is not appropriate, please advise.A diagram to understand Java

What WebService is. This question is not very good answer, but I think the following picture can give you a revelation:As you can see, traditional applications typically manage the various resources of a computer through the operating system layer, and it faces a variety of resources on the computer. And WebService is the face of various resources on the Internet. I believe this picture will give you a clear answer. There is one more thing to tell you, that is, as a developer should have a deep

Before the feeling a little bit confused, the structure of the design diagram first put up, compared to say.Models that the CAMCOCO architecture can support:1, b/s procedures, such as CRM and so on, and access to ordinary sites are no different, are from the Web server to operate;2, the app's server-side program. The app can be native, or it can be HTML5. The app has access to rest data through the Web serv
