Basic Grammar Learning Introduction:　　The Old Farmer thinks (the old farmer is my nickname to oneself), learns any computer programming language to begin with its grammar knowledge first. A computer program language consists of a set of predefined characters and the rules that write these characters. These predefined characters are called keywords or reserved words in the language, an

Grammar forms are defined in classification A context-independent grammar consists of four elements: A collection of terminologies, also known as lexical units. A non-terminator set, also known as a syntax variable. A generative set. A start symbol. Grammar g can be abstracted into the form of tuples: g = (VN, VT, P, S) Vn indicates a non-terminator set, VT

c++11 new Syntax 1:auto keywordOne of the most useful features that c++11 adds is the Auto keyword.I wonder if you've ever written such a code:STD::MAPstring, std::vector map;std:: Mapstring, std::vectorEven more complex templates are nested than this.In this case, not only is the code lengthy and error prone, but the compilation error message after the error is difficult to readThe use of auto can greatly simplify the writing of the code, but also reduce the possibility of spelling mistakesSTD:

Learning a new language must start with his main grammar, which forms the basis of the entire program, and we can see some of the features of the language from the syntax. But then again.

It is used primarily for callback (asynchronous callbacks) or for communication between two classes.

This example describes the structural grammar in the go language. Share to everyone for your reference. The specific analysis is as follows: The structure grammar represents the new allocation of a struct by the value of the Structure field as a list.Use the Name: syntax to list only some of the fields. (The order of the field names is irrelevant.) ）The special prefix constructs a pointer to the structure

In computer science, a formal grammar G = (Vt, vn, S, P) is called context-independent, where VT is a set of terminologies and Vn is a set of non-terminologies, S is the starting symbol (which must appear on the left of a production formula). P is a set of production patterns. If its production rules all take the following form: V-> W, here, V, vn, W, (Vt, vn )*. The START symbol is a special non-Terminator, and the so-called terminator is the basic s
