We’ve talked about arrays and objects before, but now we’re going to look at an array of objects. Consider a situation where you had a class called Student. While you would often need to work with a singular student, you could very likely also need to have multiple students, for example, if you were talking…
In C++ there are two ways to process strings. C-Strings which are an array of characters terminated by a null character, or the C++ style string object. The string class hides the details of how the string is stored from the user – remember one of the tasks of a class is to abstract the…
Adding an image is simultaneously easy, and difficult to do. You might think, how can something be both easy, and difficult – well, it is easy to add the image itself, but it can be a challenge to master the process. <img> Tag Let’s start with the easy – the img tag. The image tag…
The description list is slightly “new” to HTML 5. I say new, in that previous to HTML 5, it was called a “definition list” and now it is a description list. The same tags are used, just the name changed. The description list is the least used of the list containers for two reasons. First,…
An ordered list provides a list of items that should be viewed and/or performed in a certain order. In a college or university setting, you might be given a series of classes that are recommended to take in a given order due to prerequisites. Or you might have a list of steps needed to perform…
The unordered list is probably the most frequently used list, and it is sometimes (inaccurately) called a bulleted list because each item is preceded with a bullet point. In reality, an unordered list is a list of items, which the order of the items found doesn’t change their meaning. For example, I could have a…
We’ve talked about abstraction before when working with functions. The idea being using a simple to remember name, to hide a (potentially) complex process involving lots of steps. Classes are often used in the same way. They should be thought of as a “black box” which the programmer doesn’t need to worry about how the…
Previously we looked at a class Circle, which had a property radius that was publicly available. That means that any other class, or your main program could change that value. This is a problem for two reasons: First, that data could be tampered with. Another function, class, etc could directly access the variable and change…
