Naming convention (programming) 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 ...

PHP supports standard C/C++ style comments, but supports Perl style as well. Python The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [ 21 ]
Using big O notation ignores constant factors and offsets that may be very significant for practical ranges: The sieve of Eratosthenes variation known as the Pritchard wheel sieve [16] [17] [18] has an O(n) performance, but its basic implementation requires either a "one large array" algorithm which limits its usable range to the amount of ...
Hungarian notation was designed to be language-independent, and found its first major use with the BCPL programming language. Because BCPL has no data types other than the machine word, nothing in the language itself helps a programmer remember variables' types. Hungarian notation aims to remedy this by providing the programmer with explicit ...
Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by German mathematicians Paul Bachmann, [ 1] Edmund Landau, [ 2] and others, collectively called Bachmann–Landau notation or asymptotic ...
Therefore, the complexity is generally expressed by using big O notation. For example, the usual algorithm for integer multiplication has a complexity of O ( n 2 ) , {\displaystyle O(n^{2}),} this means that there is a constant c u {\displaystyle c_{u}} such that the multiplication of two integers of at most n digits may be done in a time less ...
Comparison of individual. languages. v. t. e. List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation ( set comprehension) as distinct from the use of map and filter functions.
