It's by design; this way the lexical parser is able to decide that any given string is a keyword or an identifier.
No, any keyword could be used as a identifier (a method, class or variable name). These keywords have a special meaning in the language and the compiler can not identify if they are used as a variable name or as a keyword,
Filename.
No. Keywords are reserved and cannot be used as identifiers. However, C/C++ is case-sensitive. So although register is a reserved keyword, Register is not.
The final keyword indicates that a variable (identifier) can not change his value. In case the variable refers to a reference variable (an object) the values of variables inside (the object) can change but the reference can be reassigned (to another object).
The Keyword Management System(KMS) is• A Software system for the selection, creation, registration and maintenance of InternalKeywords and Keyword Identifiers• It is implemented by a Website system that intends to use the Keyword Identifier for addressing• Maps a Keyword Identifier with the address of the Internet data location(s) (the URLs)• Registration and maintenance takes place within the computer server hosting the Website• URLs can also be local network computer addresses for Intranet users• Website owners and members have total control over the mapping process• One Internal Keyword or Keyword Identifier can be mapped to multiple URLs• Multiple Internal Keyword's or Keyword Identifiers can be mapped to one URL• Multiple Internal Keyword's or Keyword Identifiers can be mapped to multiple URLs• Can maintain the attributes and behavior of Internal Keyword or Keyword Identifier and URLsImplementing the Keyword Management System• Generate and use hundreds of relevant Internal Keywords and Keyword Identifiers• Use the Keyword Identifiers as a standardized form of addressing• Have complete control over your Electronic Resource addressing• Accuracy of Keyword-based addressing for your Electronic Resource• Empower each and every page within your Website System• Information stored deep within Website Systems can get the same visibility as the domain name• Provide a efficient and user friendly address for your dynamic content• Can be implemented by Small Business to Large Corporate Website Systems• Choose what Electronic Resources to display for each Keyword Identifier
You may use it as an identifier, because it is not a reserved word in C.
A Keyword Identifier is a new form of Internet addressing. The Keyword Identifier or KI is a Keyword based form of addressing and denotes the address of Electronic Resources. This form can be used to address web pages, products, events, processes, and other forms of data. It is an alpha-numeric, multi-lingual, natural language form that can not just be easily recognized by humans but can also be recognized as a patter by software systems.The Keyword Identifier is a unique and standardized form of Internet addressing, which denotes the address of Electronic Resources. The Keyword Identifier comprises of 'keyword' followed immediately by the character '#', followed immediately by 'domain_name', followed immediately by a '.'(Dot), followed immediately by 'TLD' (keyword#domain_name.TLD) such that -The 'keyword' may be an alpha-numeric word or multi-lingual word or natural language word or a combination of words that are separated by the space character or other characters.The 'domain_name' is the domain name or the address of a computer server.The 'domain_name' can also include any sub domain names that are used as a computer server name.The 'TLD' is an Internet Top-Level Domain (TLD) or an Internationalized Domain Name (IDN) or a country level domain (ccTLD) or a combination.The 'domain_name.TLD' can be used solely to access the Internet Website System, through an Internet accessing application and device, for which a Keyword Identifier is being generated.The Keyword Identifier therefore simply takes the formExample - keyword#yourwebsite.comThe Keyword Identifier is -The Next generation of Internet addressing and accessingA Unique and standardized form of addressingA Keyword-based address for your Webpages, Products, Events, Processes and much much moreProvides with a greater visibility for all type of Electronic ResourcesHas a presentable and user friendly look and feelEasy for website users to use and pass aroundEasy for owners to manage and controlBrand recognition of your website domain name that exists while addressing all your pagesNot a URL, but represents one or many URLsActual directory structure of data storage is not importantThis Keyword Identifier represents the address of Electronic Resources such as -A web page that ends with any type of extension.A PDF document that ends with a .PDF extension.A word document that ends with a .DOC or .DOCX extension.A text document that ends with a .TXT extension.An image that ends with any type of extension.A media file that ends with any type of extensionAny other Electronic Resources address not listed above.
A keyword is a reserved word, used by the programming language to establish actions or commands. For example, in the line: while (value < 100) { //block of code } "while" is a keyword, used to indicate iteration (loop) of what's inside the block of code. variables are user-defined words that are able to hold values. In the previous case, "value" can be thought as a variable.
A keyword identifier is one whose meaning has already been declared to the C compiler and we can't use it as variable,because if we want to do so we are trying to establish a new meaning to the keywords which is not permitted.
Various types of addressing and accessing systems exist. IP Address, DNS, Domain Name, URL and Keywords are one of the oldest, extensively and commonly used systems.The latest form of Internet Addressing is called a Keyword Identifier.A Keyword Identifier is a unique, standardized, alpha-numeric, multi-lingual, natural language form of addressing that denotes the address of Electronic Resources and Processes.The Keyword Identifier or KI is a Keyword based form of addressing and denotes the address of Electronic Resources. This form can be used to address web pages, products, events, processes, and other forms of data.
