  2. Declaration (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Declaration_(computer...

    In computer programming, a declaration is a language construct specifying identifier properties: it declares a word's (identifier's) meaning. [1] Declarations are most commonly used for functions, variables, constants, and classes, but can also be used for other entities such as enumerations and type definitions. [1]

  3. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.

    Dictionary < ' TKey, ' TValue > type (which is implemented as a hash table), which is the primary associative array type used in C# and Visual Basic. This type may be preferred when writing code that is intended to operate with other languages on the .NET Framework, or when the performance characteristics of a hash table are preferred over ...

    C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.

  6. Forward declaration - Wikipedia

    en.wikipedia.org/wiki/Forward_declaration

    However, more often it is taken to refer to the actual use of an entity before any declaration; that is, the first reference to second in the code above is a forward reference. [ 2 ] [ 3 ] Thus, we may say that because forward declarations are mandatory in Pascal, forward references are prohibited.

  7. Comparison of C Sharp and Visual Basic .NET - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and...

    C# is case sensitive and all C# keywords are in lower cases. Visual Basic and C# share most keywords, with the difference being that the default Visual Basic keywords are the capitalised versions of the C# keywords, e.g. Public vs public, If vs if. A few keywords have very different versions in Visual Basic and C#:

  8. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    C# satisfies the use-cases for these by providing anonymous delegates; see event handling for more about this. C# also provides a feature called anonymous types/classes, but it is rather different from Java's concept with the same name. It allows the programmer to instantiate a class by providing only a set of names for the properties the class ...

  9. Programming paradigm - Wikipedia

    en.wikipedia.org/wiki/Programming_paradigm

    Declarative – code declares properties of the desired result, but not how to compute it, describes what computation should perform, without specifying detailed state changes functional – a desired result is declared as the value of a series of function evaluations, uses evaluation of mathematical functions and avoids state and mutable data
