   • 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 program that doesn't return anything in C programming?

     Top Answer

     Answered May 18, 2020 · 1 votes

     Every C function specifies its return type. Specifying the return type as void is C's way of specifying that the function doesn't return a value (and presumably is meant to be called only for it side effects).

     Some other languages (Pascal, for example) make this distinction by calling value-returning subroutines "functions" and non-value-returning subroutines "procedures".

     Under a hosted implementation (basically a C implementation not targeting an embedded system), the main function is the program's entry point. The standard requires the return type of main to be int but allows implementations to specify other types. Any program that uses some other type is non-portable.

     Normally, with main defined to return int, the result returned by main is given to the calling environment to communicate some information, such as whether the program succeeded or failed. As a special case that applies only to the main function, failing to explicitly return a value is equivalent to returning 0, which denotes successful termination.

     Some implementations will allow you to define main with a return type of void, but doing so makes your program non-portable, and there is no good reason to do so. Personally, I use void main() as a filter for C books and tutorials. Any author who suggests void main() without discussion implementation-defined behavior or freestanding implementations does not know C well enough to be teaching it.

   • What is a good project to learn Windows Forms programming in C#?

     Top Answer

     Answered Jun 17, 2009 · 9 votes

     I would try to start with something fairly contained, which only touched a few new technologies. For instance, if you want to learn Windows Forms, write something which uses that but doesn't need to talk to Outlook, Google, or the Win32 API. Once you've got the hang of Windows Forms, try one extra technology - try displaying your Google Contacts and do offline editing, for example. Then add another technology... etc.

     In my experience it's hard enough to learn one new technology at a time - but that's far quicker than trying to learn two or more in one go. You inevitably get to the stage where you don't know where the problems are, and you have no confidence in any of your code because it's all new. This is particularly important if you're still fairly new to the language as well - although I'm glad to hear you started with some console apps :)

     Sorry if that sounds like I'm being a wet blanket, and I realise it sounds like you'll take far longer to get to something useful that way, but I think you're more likely to be successful in the long run.

     Find something that most importantly interests and excites you. If you pick something too boring that you don't care about you'll only give up before you get anywhere, and won't benefit at all. Don't do a rubbish project for the sake of learning a language. Do a good project, and do it in a new language as a side effect.

     Make a notepad clone. While being fairly simple it will give you a primer in some basic Windows Forms mechanisms such as using menus and reacting on their events, getting input from controls for storage on disk, reading from disk and updating controls, using Docking and Anchoring and so on.

     here error code 139 indicates segment fault that is arising because you haven't used format specifiers in the code the correct code will be

     #include <stdio.h>#include <string.h>-int main(void){ char ch = 'A'; short s = ch; printf("%d",s); printf("\n________________________\n"); short s2 = 67; char ch2 = (char)s2; printf("%c",ch2); return 0;}
