The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
Like the Qt framework's pseudo-C++ signal and slot, C# has semantics specifically surrounding publish-subscribe style events, though C# uses delegates to do so. C# offers Java-like synchronized method calls, via the attribute [MethodImpl(MethodImplOptions.Synchronized)], and has support for mutually-exclusive locks via the keyword lock.
Files.write method writes byte array or into an output file, indicated by a Path object. Files.write method also takes care of buffering and closing the output stream. Notes on the C# implementation: The ReadLines method returns an enumerable object that upon enumeration will read the file one line at a time.
Method chaining is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results.
(pred array)/array or pred {⍵ /⍨ ⍺⍺ ⍵} array: The second example is an APL dop. C# 3.0 ienum.Where(pred) or The where clause: Where is an extension method ienum is an IEnumerable Similarly in all .NET languages CFML: obj.filter(func) Where obj is an array or a structure. The func receives as an argument each element's value. Clojure
In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.
Like raw strings, there can be any number of equals signs between the square brackets, provided both the opening and closing tags have a matching number of equals signs; this allows nesting as long as nested block comments/raw strings use a different number of equals signs than their enclosing comment: --[[comment --[=[ nested comment ...
In Java, extension methods are added via Manifold, a jar file added to the project's classpath. Similar to C#, a Java extension method is declared static in an @Extension class where the first argument has the same type as the extended class and is annotated with @This.
