Dart also allows you to store different types of collections of data. Just like primitive data types, you can either create your variables with implicit data types, or allow Dart to infer them. We’ll look at the three main types: Lists List are similar to arrays in Python, Java, C++, and C#. They are an…
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…
A C String is actually an array of characters. While C strings are a thing, generally speaking it is best to use the C++ string object. However, if you run into an older application, or someone who wants to do things old style, it is good to know how to use a C-String. Additionally, any…
You pass an array to a function, very similarly as to how you would pass a non-array variable. There are two differences. You need to include square brackets after the array name so C++ knows its and array Realize that you are passing by reference. The book recommends that you always pass the size of…
An array isn’t a “data type” like you’d normally think of one. It is a collection of the same type of data, similar to a List in Python. Behind the scenes, there are a few things you need to know however: In an array, all elements must be of the same data type. When constructed,…
Like the Quick Sort, the Merge Sort uses a divide and conquer method to help sort the data. In a given array, you start to subdivide your array into smaller arrays, sorting the data as you go along, only to merge it back together when you are done. The way you sort the data is…
As you saw in a previous example, you can easily get a list of files within a Directory/Folder using the Directory helper object that is provided to you in C#. In this example, we will look at using a different helper method to get a list of sub-directories. You will need to use the System.IO…
C# provides a lot of tools to make working with the local file system much easier. For example, recently I had to get a list of files that are in a given directory. Luckily with C#, inside of the System.IO namespace is the Directory helper object. This object has a lot of static methods that…
