To make sure we are following good coding practice we are going to create a separate TaxCalculator class specifically for calculating and outputting the subtotal and grand total when given the input from the above code. Now that we are getting input from the user we are going to do the calculation so that we can give the subtotal and grand total back to the user. One thing you will notice is that Console.ReadLine() gives us a string with will have to be converted to a number later. In the code above we are using Console.Write() instead of Console.WriteLine() because we do not want to put the cursor on the next line when the user gives input. Console.Write("Enter Price of item: ") Ĭonsole.Write("Enter tax rate (in percentage): ") We will do that with the following code in the Main method of our application which is the starting point of all C# console applications. The first thing we need to do is get the price of the item and tax rate. Now that we have our new blank console application we are ready to get started. For more information on how to do this, check out my walkthrough for creating a new console application in Visual Studio. To get started, we need to create an empty C# console application in Visual Studio. For example, food items will be taxed at a different rate than general merchandise. We will add the ability to calculate different items at different tax rates. Then in the next tutorial, we are going to step it up a notch and build a full GUI (Graphical User Interface) for our app and calculate the tax based on more than one item. We will then output the subtotal and grand total based on the item amount and tax amount.įirst, we are going to start off with a simple console application that calculates the grand total of one item and its tax amount. We want to create an application that can calculate the sales tax for an item based on input from the user. By the end of this tutorial, you will be able to run your tax calculator to calculate the grand total of an item given a specific tax rate. I will show you how to get input from a user and do some calculations on that input. In this tutorial, I will show you how to create a simple tax calculator in C# using Visual Studio.
