The first, and one of the most common methods to search is using a breadth first search (BFS) pattern. In this case, you start at the root node of the tree, and evaluate the first child determining if you have a match. If not, you move to its sibling and then the next, until there…
The article tag should have independent, self-contained content. This means it should stand on its own, without the need for information from any other section of the web page. However, it can be related to articles. The difference between it, and the main tag, is that you can have multiple article tags on a web…
The main tag is used to define the main content section of the web page. The content within the web document should be unique between the pages, and not contain replicated data such as navigation links, headers, footers, sidebar data etc. Within the main tag, you can find articles, standard content which you’ve already seen,…
As you start to build more complex websites, it is important to organize the data structure efficiently and effectively. HTML 5 added several organizational tags to help provide context to the contained data. In the previous version of HTML, we’d usually use a div tag, with a user created class. However, the issue with that…
Data transformation is often simple like splitting a full name into the first and last, or vice versa. However, sometimes it is more complicated, much more complicated. I once wrote a data converter which had to convert data stored in a file with the size of data store being a certain number of bytes into…
Previously we’ve seen how variables are passed by value. While this works well in many cases, it means that the variable has to be duplicated when it is passed to the function. For large, and/or complicated, variables – like when we start using objects, this can take precious time and resources. However, C++ offers us…
Variables must be declared before they can be used in C++. This is why a lot of developers follow the best practice of defining the variables at the top of a function. Variable Scope By default variables can be used in the function that they are created. This is their scope, is is often referred…
Calling a function has a performance penalty because you have to create variables, specify scope, pause the current variables and push data onto the call stack, just to name a few reasons. C++ allows you to define an inline function, which should be short, to improve the performance. In doing so, the compiler will actually…
