As one of the most basic functions in programming, loops are an important piece to nearly every programming language. Loops enable developers to set certain portions of their code to repeat through a number of loops which are referred to as iterations. This topic covers using multiple types of loops...

Protocols are a way of specifying how to use an object. They describe a set of properties and methods which a class, structure, or enum should provide, although protocols pose no restrictions on the implementation. A Swift protocol is a collection of requirements that conforming types must imp...

It's worth noting that staging has little to do with 'files' themselves and everything to do with the changes within each given file. We stage files that contain changes, and git tracks the changes as commits (even when the changes in a commit are made across several files). The distinction betwe...

This topic illustrates how to avoid adding unwanted files (or file changes) in a Git repo. There are several ways (global or local .gitignore, .git/exclude, git update-index --assume-unchanged, and git update-index --skip-tree), but keep in mind Git is managing content, which means: ignoring actuall...

“ An optional value either contains a value or contains nil to indicate that a value is missing” Excerpt From: Apple Inc. “The Swift Programming Language (Swift 3.1 Edition).” iBooks. https://itun.es/us/k5SW7.l Basic optional use cases include: for a constant (let), use of an optional within a loo...

Function pointers are pointers that point to functions instead of data types. They can be used to allow variability in the function that is to be called, at run-time. returnType (*name)(parameters) typedef returnType (*name)(parameters) typedef returnType Name(parameters); Name *n...

Haskell is an advanced purely-functional programming language. Features: Statically typed: Every expression in Haskell has a type which is determined at compile time. Static type checking is the process of verifying the type safety of a program based on analysis of a program's text (source...

a = [] # using array literal a = Array.new # equivalent to using literal a = Array.new(5) # create an array with 5 elements with value of nil. a = Array.new(5, 0) # create an array with 5 elements with default value of 0.

Anchor tags are commonly used to link separate webpages, but they can also be used to link between different places in a single document, often within table of contents or even launch external applications. This topic explains the implementation and application of HTML anchor tags in various roles. ...

An operator in a programming language is a symbol that tells the compiler or interpreter to perform a specific mathematical, relational or logical operation and produce a final result. C has many powerful operators. Many C operators are binary operators, which means they have two operands. For exa...

For many programmers the regex is some sort of magical sword that they throw to solve any kind of text parsing situation. But this tool is nothing magical, and even though it's great at what it does, it's not a full featured programming language (i.e. it is not Turing-complete). What does 'regu...
