Regular Expressions, often called RegEx, is a sequence of characters that defines a search pattern to run against another string of data. This is often used to perform a find and replace or check for validation. Different languages apply regular expressions differently. The strictest use the full range of special characters and commands, while others…
We’ve already looked at styling rows within a table, however, you can style more. By default a table doesn’t have any borders, color, or anything else. Luckily, like all HTML elements, you can apply styles to your elements. And since a table is made up of a lot of elements, you can apply styles to…
C++ allows you to define functions for operators, this is called operator overloading. Now why would you need to do that? Well, consider the Circle class we defined earlier. Let’s say I needed to compare two circles to see which one was larger, normally I’d write something like: The problem is, C++ has know way…
Using arrays to store a collection of variables, even objects, if very beneficial. However, it does have some limitations given that arrays are of a fixed size, and cannot shrink or grow with use. This means you either run out of space after a set of time, or you waste a lot of space as…
Not only can you use templates for a primitive data type within functions, but also within classes. Consider the following example: The methods are similar to a non-template class, however, each method is a template itself, so you have to adjust a few things. For example, you have to specify template<typename T> before each method….
Templates are like a way to simplify making overloaded functions, by allowing for a function with generic data types to be written, to have the compiler change at compile time. The Generic Version of this would look like: Think of something like where you want to determine the max value of two variables. Well, you…
In addition to the standard tags that you often find people using, there are several optional tags which can be used to help organize the data. Browsers and/or libraries will sometimes use these additional tags to help organize your information and make it more user accessible, especially when dealing with large amounts of information. <thead>…
A table actually isn’t a single tag, but is made up of several tags working together. Some of these tags are required, however, most are optional. Now tables are a bit unique because of the number of optional tags you can define, and how that will help you design and improve the usability of the…
