[Valid tive C ++ Reading Notes] 001 _ clause 01 _ regard C ++ as a Language Federation

With regard to these terms, the author has been emphasizing to us that we should not regard C ++ as the pure language we have learned, c ++ should be regarded as a federated language with multiple independent features.

1. c ++ developed from C and is compatible with all c syntax features. Therefore, the first federated in C ++ --C language, which is a process-oriented representative language.

2. From the very beginning, C ++ introduced the object-oriented feature, namely the name C with classes at the beginning, which is the second Federation of C ++ --Object-oriented language.

3. c ++ template. This part of the syntax makes C ++ support generic programming. Therefore, this can be the third federated of C ++ --TemplateProgramming Language.

4. the last is the famous STL, which is the masterpiece of C ++ generic programming. Although it is under the C ++ language framework, it still needs to follow its own rules when using it, that is, the fourth federated --STL.

When the author suggests that we should not use C ++ as a language, but as N languages, because C ++ covers a wide range, this leads to the extreme complexity of C ++ and various kinds of its rule conventions, therefore, when we use C ++ to switch to another method of C ++ in one way of work, we must be able to instantly adapt to the Conventions of different use methods.

In short, in my opinion, C ++ itself has become a mixture of all languages, covering the process-oriented, object-oriented, functional, paradigm, and meta-programming languages. At the same time, I personally summarized a sentence to describe C ++:

C ++ is a very flexible language with a bunch of syntax constraints, but it also provides a way to lift these constraints. Therefore, C ++ is a language that gives you constraints and full freedom. In short, your creativity can be used in both the constraints and the constraints.
