Steganography (pronounced STEHG-uh-NAH-gruhf-ee, from Greek steganos, or "covered," and graphie, or "writing") is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step further by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your data will fail to know it contains encrypted data.
OS is a mobile operating system developed and distributed by Apple Inc. It was originally released in 2007 for the iPhone, iPod Touch, and Apple TV. iOS is derived from OS X, with which it shares the Darwin foundation. iOS is Apple's mobile version of the OS X operating system used in Apple computers.
迅速4是一个新的programming language developed by Apple Inc for iOS and OS X development. Swift 4 adopts the best of C and Objective-C, without the constraints of C compatibility. Swift 4 uses the same runtime as the existing Obj-C system on Mac OS and iOS, which enables Swift 4 programs to run on many existing iOS 6 and OS X 10.8 platforms.

Headers, and their purpose As programs grow larger and larger (and include more files), it becomes increasingly tedious to have to forward declare every function you want to use that lives in a different file. Wouldn’t it be nice if you could put all your declarations in one place?
Regular expressions are a pattern matching standard for string parsing and replacement. They are used on a wide range of platforms and programming environments. Originally missing in Visual Basic, regular expressions are now available for most VB and VBA versions.
Bubble sort is a simple and well-known sorting algorithm. It is used in practice once in a blue moon and its main application is to make an introduction to the sorting algorithms. Bubble sort belongs to O(n2) sorting algorithms, which makes it quite inefficient for sorting large data volumes. Bubble sort is stable and adaptive.
Bubble Sort is an algorithm which is used to sort N elements that are given in a memory for eg: an Array with N number of elements. Bubble Sort compares all the element one by one and sort them based on their values.

The Android SDK is the bare bones version of the package and it doesn’t include either of the two IDEs (interactive development environments): Android Studio or Eclipse. Android Studio includes its own IDE as well as a second IDE, known as Eclipse. If you elect to download Android Studio, on the other hand, your package will contain both IDEs, as well as the Android SDK.
This page includes detailed information to help you with installing Visual Studio 2015, our integrated suite of productivity tools for developers. We've also included links to get you quickly to information about features, editions, system requirements, downloads, and more.
We've partnered with Dartmouth college professors Tom Cormen and Devin Balkcom to teach introductory computer science algorithms, including searching, sorting, recursion, and graph theory. Learn with a combination of articles, visualizations, quizzes, and coding challenges.

UML is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. UML was created by Object Management Group and UML 1.0 specification draft was proposed to the OMG in January 1997. This tutorial gives a complete understanding on UML.
UML stands for Unified Modeling Language. UML is a way of visualizing a software program using a collection of diagrams. The current UML standards call for 13 different types of diagrams: class, activity, object, use case, sequence, package, state, component, communication, composite structure, interaction overview, timing, and deployment.
These diagrams are organized into two distinct groups: structural diagrams and behavioral or interaction diagrams.
You can create any 2D or 3D game with Unity. You can make it with ease, you can make it highly-optimized and beautiful, and you can deploy it with a click to more platforms than you have fingers and toes. What’s more, you can use Unity’s integrated services to speed up your development process, optimize your game, connect with an audience, and achieve success.

Multiple Visio Versions Visio lets you transform complicated text and tables that are hard to understand into visual diagrams that communicate information at a glance. There are many kinds of Visio diagrams, including organization charts, network diagrams, workflows, and home or office plans. Getting started with Visio can be summarized into three basic steps: using a template, arranging and connecting shapes, and modifying shapes with text.
Visio also helps to create detailed org charts, floor plans, pivot diagrams, etc. This tutorial will help you understand the basics of the program and how you can use it to create informative diagrams for home or enterprise use.
