   • What is a production in the context of the C Programming language?

     Top Answer

     Answered Jun 03, 2022 · 6 votes

     In computer science, formal grammars are described using production rules. For example, a rule of the form:

     P → xyz

     says the symbol P may be replaced by the symbols xyz, and a rule of the form

     Q → aP | bP

     says the symbol Q may be replaced by the symbol a and the symbol P or by the symbol b and the symbol P.

     The formal grammar designates a start symbol, such as Q, and says which symbols are nonterminal symbols (placeholders that do not appear in the final string) and which are terminal symbols (that may appear in the final string). If Q is the start symbol for the grammar with the two rules above, then these rules describe a grammar that contains two strings, axyz and bxyz, because those are the only two strings that can be made with those rules. The set of strings a grammar can produce is called its language.

     λ is commonly used the mean an empty string, one with no symbols.

     This grammar with nonterminal symbol S, terminal symbols a and b, and start symbol S:

     S → aSbb | λ

     can produce the empty string by replacing S with the empty string, or it can produce abb by replacing S with aSbb and then the new S with the empty string, or it can produce aabbbb by replacing S with aSbb and then replacing the new S with aSbb, yielding aaSbbbb, and then replacing S with the empty string, yielding aabbbb. We can see the language of this grammar is the set of all strings containing some number of a characters (possibly zero) followed by twice as many b characters.

     The C standard defines the C language using a formal grammar (with some qualifications and modifications in English). For example, it contains this production (where it uses “:” instead of the “→” I used above and uses separate lines instead of “|” to indicate a choice):

     statement:         labeled-statement         compound-statement         expression-statement         selection-statement         iteration-statement         jump-statement

     Regarding the other terminology you marked in bold:

     undefined terminal symbols integer-constant,…

     The C grammar given in The C Programming Language appears to be a partial grammar, leaving integer-constant as an undefined symbol, and hence acting as a terminal symbol. In the official ANSI C 1990 standard, it is a defined non-terminal in the official ANSI C 1990 standard.

     … the typewriter style words and symbols are terminals given literally.

     This is clearer in the original, where the fonts used make it evident the “typewriter” style is a fixed-width font:

     … the typewriter style words and symbols are terminals given literally.

     This, with its preceding text, means that, in the grammar, words in italic, like declaration, are non-terminal symbols of the grammar that “become something else” by productions of the grammar, while words in the “typewriter” font, like typedef, are terminal symbols and they are symbols for the literal characters in their names; typedef in the grammar means the characters t, y, p, e, d, e, and f in the source code.

     …to duplicate each production with an opt symbol, once with the symbol and once without…

     The standard uses a subscript “opt”, like this:

     P: Q Ropt

     to mean that R is optional. Formally, this is actually two rules:

     P → Q R P → Q

     meaning there is a rule that replaces P with Q R and a rule that replaces P with Q, and either may be used. Hence, the R is optional. Using the “opt” subscript is just a different way of writing the rules.

     … this grammar is acceptable to the YACC parser-generator. It has only one conflict, generated by the if-else ambiguity.

     In computer science theory, a parser is software that checks whether a string is in a language. (In practice, it often does other useful things at the same time, like assigning “meaning” to the string by interpreting parts of it as numbers, parts as variables, and so on.) YACC is software that reads a specification of a grammar and produces source code for a parser for the language the grammar describes.

     The type of parser that YACC generates requires deciding which production will be applied as each token is read. A conflict occurs when the grammar is inadequate determine which production to apply. In the C formal grammar, if (x) if (y) S1 else S2 can be produced in two ways, one that associates else S2 with the first if and one that associates else S2 with the second if. This has to be resolved by adding information to the grammar; YACC is told to associate the else S2 with the most recent if that does not currently have an else.

   • What is a "Production" in plain English?

     Top Answer

     Answered Aug 20, 2013 · 4 votes

     To explain what a production is I'd like to introduce a bit of context first.

     The dragon book states that a context free grammar has 4 components:

     • a set of terminal symbols (tokens)
     • a set of non-terminal symbols (syntactic variables)
     • a set of productions of the form: non-term --> sequence of terminals and non-terminals
     • a non-terminal symbol designated as the start symbol

     It is also said that parsing is the problem of taking a string of terminals (the source code) and figuring out what are the steps required to derive this string of terminals from the start symbol of the grammar.

     Now that this has been said, a production is essentially a possible (intermediate) step. I say possible because some symbols can derive into different sequences.

     For example, let's make a simple grammar to represent an arbitrarily long sequences of a's ending with a b. The 4 components of this grammar would be:

     • Terminals: a, b
     • Non-terminals: S, X
     • Rules: S --> X, X --> aX, X --> ab
     • Start symbol: S

     From the description I gave above "aaaab" should be derivable from this grammar. Let's see if that holds up. We start from, the start symbol, and then apply productions until a) we get the final sequence, b) we exhaust all possibilities without succeeding (meaning the sequence is not "grammatically correct").

     SX (after applying S --> X)aX (after applying X --> aX)aaX (after applying X --> aX)aaaX (after applying X --> aX)aaaab (after applying X --> ab)-

     And we're done, we got the original sequence. So as you can see we re-wrote the non-terminal symbols by applying rules (one of them we applied recursively) which transformed the sequence into a new sequence of symbols at every step and we did so until we had the final sequence.

     Two guesses: a data dictionary provides information about tables in a database: field names, field types, field sizes stored procedures associated with certain tables

     OR

     simply a fixed table that provides lookup or validation for a separate updatable table.

   • What is &'a in Rust Language

     Top Answer

     Answered Jan 23, 2021 · 87 votes

     I found this and this and this and this that explains my question.

     The 'a reads ‘the lifetime a’. Technically, every reference has some lifetime associated with it, but the compiler lets you elide (i.e. omit, see "Lifetime Elision") them in common cases.

     fn bar<'a>(...)-

     A function can have ‘generic parameters’ between the <>s, of which lifetimes are one kind. The <> is used to declare lifetimes. This says that bar has one lifetime, 'a.

     Rust has two main types of strings: &str and String. The &str are called ‘string slices’. A string slice has a fixed size, and cannot be mutated. It is a reference to a sequence of UTF-8 bytes.

     let greeting = "Hello there."; // greeting: &'static str-

     "Hello there." is a string literal and its type is &'static str. A string literal is a string slice that is statically allocated, meaning that it’s saved inside our compiled program, and exists for the entire duration it runs. The greeting binding is a reference to this statically allocated string. Any function expecting a string slice will also accept a string literal.

     In the above example

     struct Person<'a> { }-

     requires to contain <'a> as the name is defined using:

     name: &'a str,-

     which is called by:

     let name = "Peter";-

     If interested to avoid the usage of 'a then the above code can be re-written as:

     #[derive(Debug)]struct Person { // instead of: struct Person<'a> { name: String, // instead of: name: &'a str age: u8}fn main() { let name = String::from("Peter"); // instead of: let name = "Peter"; which is &'static str let age = 27; let peter = Person { name, age }; // Pretty print println!("{:#?}", peter);}

     As mentioned by @DimitrisSfounis in the comments, in short, "Why is 'a there?" ---- Because the struct definition ties it to a referenced object (in this case, every struct Person instance is referencing a &str) you want to specificly declare an arbitary lifetime and tie these two things together: You want a struct Person instance to only live as long as its referenced object (hence Person<'a> and name: &'a str) so dangling references after each other's death is avoided.

   • What is a chunker in Natural Language Processing?

     Top Answer

     Answered Jan 21, 2011 · 14 votes

     According to these slides, chunking is an alternative to parsing that provides a partial syntactic structure of a sentence, with a limited tree depth, as opposed to full on parsing.

     It is more limited than full parsing, but is sufficient when it comes to extracting or ignoring information, and is thus many times used, as it's faster and more robust than parsing.

     Much more information is available in the slides.
