For example, types for SI units have been standardized in the F# core library, in Microsoft.FSharp.Data.UnitSystems.SI. Open the appropriate sub-namespace, UnitNames or UnitSymbols, to use them.

Various forms of lists are either a basic data type or can be fairly easily constructed in most programming environments. For example, linked lists can be constructed if the programming language provides structures and pointers or references, or even with just two (resizable) arrays, one of next in...

SpriteKit functionality can be implemented in a subclass of SKScene. For example, a game may implement the main game functionality within an SKScene subclass called GameScene. In Swift: import SpriteKit class GameScene: SKScene { override func didMoveToView(view: SKView) { /* Co...

It's best for readability (and your sanity) to avoid escaping the escapes. That's where raw strings literals come in. (Note that some languages allow delimiters, which are preferred over strings usually. But that's another section.) They usually work the same way as this answer describes: [A] ba...

This program demonstrates how to run another process using fork() and wait its termination using waitpid(): fork() creates an identical copy of the current process. The original process is the parent process, while the newly created one is the child process. Both processes continue exactly afte...

Following script illustrates how to receive events according to visibility to a set camera. This script uses several performance heavy methods for brevity. using UnityEngine; using System.Linq; public class CullingGroupCameraBehaviour : MonoBehaviour { CullingGroup localCullingGroup;...

String literals are used to specify arrays of characters. They are sequences of characters enclosed within double quotes (e.g. "abcd" and have the type char*). The L prefix makes the literal a wide character array, of type wchar_t*. For example, L"abcd". Since C11, there are ot...

Floating point literals are used to represent signed real numbers. The following suffixes can be used to specify type of a literal: SuffixTypeExamplesnonedouble3.1415926 -3E6f, Ffloat3.1415926f 2.1E-6Fl, Llong double3.1415926L 1E126L In order to use these suffixes, the literal must be a floating p...

Character literals are a special type of integer literals that are used to represent one character. They are enclosed in single quotes, e.g. 'a' and have the type int. The value of the literal is an integer value according to the machine's character set. They do not allow suffixes. The L prefix bef...

To be more clear, let's create a script named showarg: #!/usr/bin/env bash printf "%d args:" $# printf " <%s>" "$@" echo Now let's see the differences: $ var="This is an example" $ showarg $var 4 args: <This> <is> <an> <exa...

VB now allows string literals that split over multiple lines. Old syntax: Dim text As String = "Line1" & Environment.NewLine & "Line2" New syntax: Dim text As String = "Line 1 Line 2"

Normally Android-SQLiteOpenHelper does not allow fully qualified path names where the database should be stored. So public database files are not possible. You can use the SQLiteOpenHelper with a custom path if you provide a custom ContextClass and if you have write access in the target directory. ...
