This course is the second course in a series that aims to prepare you for a role working as a programmer. In this course, you will be introduced to the five main concepts in procedural programming: user input, console output, variable declaration and assignment, decision branching and iteration. Labs will allow the students to apply the material in the lectures in simple computer programs designed to re-enforce the material in the lesson. Learners will need to have a local machine with any one of the following operating systems; Windows 7 SP1 or higher, macOS 10.1.13 or higher, or almost any version of Linux from the last several years. The learner will either need to download the free community edition of Visual Studio or the open source .NET Core installation. We will walk you through the process of getting your local environment set up as part of the course.
Console Input and Output
In this module, we roll up our sleeves and start coding! We will learn to use both Visual Studio to develop code and the command line. The Visual Basic Programs can be written on a Windows, Mac OS or Linux machine and I will show you how to do so. Our first programs will focus on reading input from the keyboard and outputting the results of the program to the console output.
In the second module of this course, we will look at how computers store data during the execution of a program. We will look at storing whole numbers, decimal numbers, boolean values and strings. We will explore how you can convert between different types of variables. Lastly, we will look at how long a variable stays in existence and when it is visible to the pieces of the code.
In the third module of this course, we will learn how to change the flow of a program’s execution based on a test. We will look at single tests utilizing if statements in our code. We follow up with multiple tests with the addition of the else clause. Lastly, we look at the case statement as an alternative expression of the flow of the program.
In the fourth module of this course, we learn how to change the flow of our programs by repeating code iteratively. We will start with a look at loops that repeat a fixed number of times. We will follow up with writing loops that continue while a test is positive. Lastly, we will look at how we can modify the flow to immediately break from a loop or jump back to the test condition.
