In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation. Reasons for using a naming convention as opposed to allowing programmers to choose any character sequence include the following To reduce the effort needed to read and understand source code 1To enable code reviews to focus on more important issues than arguing over syntax and naming standards. To enable code quality review tools to focus their reporting mainly on significant issues other than syntax and style preferences. The choice of naming conventions can be an enormously controversial issue, with partisans of each holding theirs to be the best and others to be inferior. Colloquially, this is said to be a matter of dogma. Many companies have also established their own set of conventions. Potential benefitseditSome of the potential benefits that can be obtained by adopting a naming convention include the following to provide additional information i. ChallengeseditThe choice of naming conventions and the extent to which they are enforced is often a contentious issue, with partisans holding their viewpoint to be the best and others to be inferior. Moreover, even with known and well defined naming conventions in place, some organizations may fail to consistently adhere to them, causing inconsistency and confusion. These challenges may be exacerbated if the naming convention rules are internally inconsistent, arbitrary, difficult to remember, or otherwise perceived as more burdensome than beneficial. ReadabilityeditWell chosen identifiers make it significantly easier for developers and analysts to understand what the system is doing and how to fix or extend the source code to apply for new needs. For example, although the statementis syntactically correct, its purpose is not evident. Contrast this with weeklypayhoursworkedpayrate which implies the intent and meaning of the source code, at least to those familiar with the context of the statement. Common elementseditThe exact rules of a naming convention depend on the context in which they are employed. Nevertheless, there are several common elements that influence most if not all naming conventions in common use today. Length of identifierseditFundamental elements of all naming conventions are the rules related to identifier length i. Apache Commons Io Copy File. Some rules dictate a fixed numerical bound, while others specify less precise heuristics or guidelines.

Identifier length rules are routinely contested in practice, and subject to much debate academically. Some considerations shorter identifiers may be preferred as more expedient, because they are easier to typeextremely short identifiers such as i or j are very difficult to uniquely distinguish using automated search and replace toolslonger identifiers may be preferred because short identifiers cannot encode enough information or appear too crypticlonger identifiers may be disfavored because of visual clutter. It is an open research issue whether some programmers prefer shorter identifiers because they are easier to type, or think up, than longer identifiers, or because in many situations a longer identifier simply clutters the visible code and provides no perceived additional benefit. Brevity in programming could be in part attributed to early linkers which required variable names to be restricted to 6 characters to save memory. A later advance allowed longer variable names to be used for human comprehensibility, but where only the first few characters were significant. In some versions of BASIC such as TRS 8. Level 2 Basic, long names were allowed, but only the first two letters were significant. This feature permitted erroneous behaviour that could be difficult to debug, for example when names such as VALUE and VAT were used and intended to be distinct. Letter case and numeralseditSome naming conventions limit whether letters may appear in uppercase or lowercase. Other conventions do not restrict letter case, but attach a well defined interpretation based on letter case. Some naming conventions specify whether alphabetic, numeric, or alphanumeric characters may be used, and if so, in what sequence. Multiple word identifierseditA common recommendation is Use meaningful identifiers. A single word may not be as meaningful, or specific, as multiple words. Consequently, some naming conventions specify rules for the treatment of compound identifiers containing more than one word. As most programming languages do not allow whitespace in identifiers, a method of delimiting each word is needed to make it easier for subsequent readers to interpret which characters belong to which word. Historically some early languages, notably FORTRAN 1. ALGOL 1. 95. 8, allowed spaces within identifiers, determining the end of identifiers by context. This was abandoned in later languages due to the difficulty of tokenization.

Hi guys, Have just searched the exchange for my trouble and none of the pervious solutions to this problem apply to me. I have a hyperlink in my Word. It is possible to write names by simply concatenating words, and this is sometimes used, as in mypackage for Java package names,3 though legibility suffers for longer terms, so usually some form of separation is used. Delimiter separated words. One approach is to delimit separate words with a nonalphanumeric character. The two characters commonly used for this purpose are the hyphen and the underscore e. The hyphen is used by nearly all programmers writing COBOL 1. Forth 1. 97. 0, and Lisp 1. Unix for commands and packages, and is used in CSS. This convention has no standard name, though it may be referred to as lisp case or COBOL CASE compare Pascal case, kebab case, or other variants. Of these, kebab case, dating at least to 2. By contrast, languages in the FORTRANALGOL tradition, notably languages in the C and Pascal families, used the hyphen for the subtractioninfix operator, and did not wish to require spaces around it as free form languages, preventing its use in identifiers. An alternative is to use underscores this is common in the C family including Python, with lowercase words, being found for example in The C Programming Language 1. Underscores with upper case, as in UPPERCASE, are commonly used for C preprocessor macros, hence known as MACROCASE, and for environment variables in Unix, such as BASHVERSION in bash. Letter case separated words. Another approach is to indicate word boundaries using medial capitalization, called Camel. Case, Pascal case, and many other names, thus rendering two words as either two. Words or Two. Words. This convention is commonly used in Pascal, Java, C, and Visual Basic. Treatment of acronyms in identifiers e. XML and HTTP in XMLHttp. Request varies. Some dictate that they be lowercased e. Xml. Http. Request to ease typing and readability, whereas others leave them uppercased e. XMLHTTPRequest for accuracy. See also Letter case Special case styles. Metadata and hybrid conventionseditSome naming conventions represent rules or requirements that go beyond the requirements of a specific project or problem domain, and instead reflect a greater overarching set of principles defined by the software architecture, underlying programming language or other kind of cross project methodology. What is DOC What Opens a DOC File Format List from What. Is. com. DOC is a document file format used by Microsoft Word, also used with most word processing software, including Open. Office. DOC stands for DOCument file. A DOC file can contain formatted text, images, tables, graphs, charts, page formatting, and print settings. With each version of Microsoft Word, the standards for the DOC format change slightly which can cause some compatibility issues.
