This is a comparison of the features of the type systems and type checking of multiple programming languages. Brief definitions A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.
Some compiled languages such as Ada and Fortran, and some scripting languages such as IDL, MATLAB, and S-Lang, have native support for vectorized operations on arrays. For example, to perform an element by element sum of two arrays, a and b to produce a third c, it is only necessary to write
The term cross-reference (abbreviation: xref) can refer to either: . An instance within a document which refers to related information elsewhere in the same document. In both printed and online dictionaries cross-references are important because they form a network structure of relations existing between different parts of data, dictionary-internal as well as dictionary external.
Some languages define a special character as a terminator while some, called line-oriented, rely on the newline. Typically, a line-oriented language includes a line continuation feature whereas other languages have no need for line continuation since newline is treated like other whitespace. Some line-oriented languages provide a separator for ...
In 1993, Sybex, Inc. (computer books) published the Xbase Cross Reference Handbook, by Sheldon M. Dunn, another cross reference of the most commonly used xBase languages at that time – dBASE III+, dBASE IV, FoxPro for DOS, FoxPro for Windows, FoxPro for Macintosh and Clipper 5.1. At 1,352 pages and 5.1 pounds shipping weight, the Cross ...
OpenGrok is a source code cross-reference and search engine.It helps programmers search, cross-reference, and navigate source code trees to aid program comprehension.. It can read program file formats and version control histories such as Monotone, Subversion, Mercurial, Git, ClearCase, Perforce, AccuRev, Razor, and Bazaar.
Different languages compile into a shared runtime. A virtual machine (VM) is a specialised intermediate language that several different languages compile down to. Languages that use the same virtual machine can interoperate, as they will share a memory model and compiler and thus libraries from one language can be re-used for others on the same VM.
LXR Cross Referencer, usually known as LXR, is a general-purpose source code indexer and cross-referencer for code comprehension that provides web-based browsing of source code, with links to the definition and usage of any identifier.
