  2. Comparison of programming languages (associative array)

    en.wikipedia.org/wiki/Comparison_of_programming...

    In Java associative arrays are implemented as "maps", which are part of the Java collections framework. Since J2SE 5.0 and the introduction of generics into Java, collections can have a type specified; for example, an associative array that maps strings to strings might be specified as follows:

  3. Comparison of programming languages (array) - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_programming...

    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 c = a + b In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x)

  4. Foreach loop - Wikipedia

    en.wikipedia.org/wiki/Foreach_loop

    In Perl, foreach (which is equivalent to the shorter for) can be used to traverse elements of a list. The expression which denotes the collection to loop over is evaluated in list-context and each item of the resulting list is, in turn, aliased to the loop variable. List literal example:

  6. Row- and column-major order - Wikipedia

    en.wikipedia.org/wiki/Row-_and_column-major_order

    Programming languages or their standard libraries that support multi-dimensional arrays typically have a native row-major or column-major storage order for these arrays. Row-major order is used in C / C++ / Objective-C (for C-style arrays), PL/I , [ 4 ] Pascal , [ 5 ] Speakeasy , [ citation needed ] and SAS .

    No multidimensional arrays (rectangular arrays), but arrays of references to arrays (jagged arrays). Multidimensional arrays (rectangular arrays), and arrays of references to arrays (jagged arrays). Arrays cannot be resized (though use of the System.arraycopy() method can allow for multi-step array resizing)

  8. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...

  9. Parallel Extensions - Wikipedia

    en.wikipedia.org/wiki/Parallel_Extensions

    The main concept in the Parallel Extensions to .NET is a Task, which is a small unit of code, usually represented as a lambda function, that can be executed independently. Both PLINQ and the TPL API provides methods to create the Tasks – PLINQ divides a query into smaller Tasks, and the Parallel.For , Parallel.ForEach and Parallel.Invoke ...
