Just like with flowcharts where you can repeat a series of steps, you can repeat a series of steps in pseudocode. And just like with Flowcharts, we have two main types of repetition, conditional loops and counting loops. In this example we are going to work with conditional loops. Setting the Condition First we need…
The Do-While loop is similar to the while loop. It is a conditional loop, just like the while loop, running the body of the loop while the condition is met. However, the big difference is that the do-while loop is a post-test loop. That means that the body runs at least once, and then there…
Previously, when we read from a file, it was easy to know what we were reading, as we created the file, and knew how many data elements we put into the file. But what if we don’t know? We just know we need to read the whole file and work with that data? That’s were…
A while loop says to perform a set of operations while a condition is true. It is known as a pre-test loop, because the condition is tested before the loop is run at all, meaning the body of the loop may never run. The general form for a while loop is: Notice that the loop…
Opening a file in Python is actually very simple. It follows the general form of: The file_variable is the variable we will use to reference the file in the Python code. The filename includes the whole file, including path (if you are not in the same folder), and extension. The mode specifies whether you are…
When you work with Loops, you’ll find life is a bit easier if you know some of these tips. Simplifying Math The book calls this first tip Augmented Operators, other languages refer to it as shortcut math. Either way, the end result is the same. Quite often you will be working with a variable and…
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…
