  2. Indexer (programming) - Wikipedia

    en.wikipedia.org/wiki/Indexer_(programming)

    In this example, the indexer is used to get the value at the nth position, and then to get the position in the list referenced by its value. The output of the code is: John is the member number 0 of the doeFamily Jane is the member number 1 of the doeFamily

    «FUNCTION» BYTE-LENGTH(string) number of characters and number of bytes, respectively COBOL: string length string: a decimal string giving the number of characters Tcl: ≢ string: APL: string.len() Number of bytes Rust [30] string.chars().count() Number of Unicode code points Rust [31]

  4. Enumerated type - Wikipedia

    en.wikipedia.org/wiki/Enumerated_type

    If a value (termed a raw value) is provided for each enumeration case, the value can be a string, a character, or a value of any integer or floating-point type. Alternatively, enumeration cases can specify associated values of any type to be stored along with each different case value, much as unions or variants do in other languages.

  5. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    Like in C and C++ there are functions that group reusable code. The main difference is that functions, just like in Java, have to reside inside of a class. A function is therefore called a method. A method has a return value, a name and usually some parameters initialized when it is called with some arguments.

  6. Type conversion - Wikipedia

    en.wikipedia.org/wiki/Type_conversion

    Existing Eiffel software uses the string classes (such as STRING_8) from the Eiffel libraries, but Eiffel software written for .NET must use the .NET string class (System.String) in many cases, for example when calling .NET methods which expect items of the .NET type to be passed as arguments. So, the conversion of these types back and forth ...

  7. Type punning - Wikipedia

    en.wikipedia.org/wiki/Type_punning

    C# only allows pointers to so-called native types, i.e. any primitive type (except string), enum, array or struct that is composed only of other native types. Note that pointers are only allowed in code blocks marked 'unsafe'.

  8. Type signature - Wikipedia

    en.wikipedia.org/wiki/Type_signature

    A function signature consists of the function prototype. It specifies the general information about a function like the name, scope and parameters. Many programming languages use name mangling in order to pass along more semantic information from the compilers to the linkers. In addition to mangling, there is an excess of information in a ...

  9. Tagged union - Wikipedia

    en.wikipedia.org/wiki/Tagged_union

    Common examples are the use of reserved values, where, for example, a function returning a positive number may return -1 to indicate failure, and sentinel values, most often used in tagged pointers. Sometimes, untagged unions are used to perform bit-level conversions between types, called reinterpret casts in C++.
