Microsoft visual studio 2013 c# tutorial free. How to Download and Install Visual Studio for C# in Windows
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. In this tutorial, you use Visual Studio to create and run a C console app, and explore some features of the Visual Studio integrated development environment IDE.
This tutorial is part 1 of a two-part tutorial series. In part 2you extend this app to add more projects, learn debugging tricks, and reference third-party packages. If you haven't already installed Visual Studio, go to the Visual Studio downloads page to install it for free.
To start, create a C application project. The project type comes with all the template files you need. In the Create a new project window, choose C from the Language list. Next, choose Windows from the Platform list and Console from the project types list. After продолжение здесь apply the language, platform, and project type filters, choose the Console Application template, and then select Microsoft visual studio 2013 c# tutorial free.
If you don't see the Console Application template, select Install more tools and features. Then, in the Visual Studio Installer, choose the. NET Core cross-platform development workload. After that, choose the Modify button in the Visual Studio Installer. You might be prompted to save your work; if so, do so.
Next, choose Continue to install the workload. Then, return to step 2 in this " Create a project " procedure. In the Configure your new project window, type or enter Calculator in the Project name box. Then, choose Next.
In the Additional information window. NET Core 3. If not, select. Then, choose Create. Visual Microsoft visual studio 2013 c# tutorial free opens your new project, which includes default "Hello World" code. To view it in the editor, select the code file Program. If you press F5, you can run the default program in Debug mode. After the application runs in the debugger, microsoft visual studio 2013 c# tutorial free console window stays open.
Press any key to close the console window. Microsoft visual studio 2013 c# tutorial free the Create a new project window, select All languagesand then choose C from the dropdown list. Choose Windows from the All platforms list, and choose Console from the All project types list. After you apply the language, platform, and project type filters, choose the Console App template, and then select Next. If you don't see the Console App template, select Install more tools and features.
In the Visual Studio Installer, choose the. NET desktop development workload, and then select Modify. In the Configure your new project window, type or enter Calculator in the Project name box, and then select Next. NET 6. Select Create. The single code statement calls the WriteLine method to display the literal string "Hello, World! Starting with. NET 6, new projects using the console template generate different code than previous versions.
To learn more, see the New C templates generate top-level statements page. Specifically, delete the line that says, Console. WriteLine "Hello World! Notice that when you do so, the IntelliSense feature in Visual Studio offers you the option to ссылка на подробности the entry.
Choose the green Start button next to Calculator to build and run your program, or press F5. Optional You can change the operator to change the result.
Then, when you run the program, the result changes, too. In Solution Explorerin the right pane, select Program. In the code editor, replace the default "Hello World" code that says Console. If you type the code, the Visual Studio IntelliSense feature offers you the microsoft visual studio 2013 c# tutorial free to autocomplete the entry.
To build and run your app, press F5or select the green arrow next to the name Calculator in the top toolbar. Optionally, you can change the operator to change the result. When you run the app, the result changes accordingly. In the console window, follow the prompts to add the numbers 42 and together. The current calculator app only accepts and returns whole numbers. For example, if you run the app and divide the number 42 by the numberyour result is zero, which isn't exact.
From program. Run your calculator app again, and divide the number 42 by the number Now the app can produce decimal results. Make a few more tweaks to the code so the app can calculate decimals too. Use the Find and Replace control to change each instance of the float variable to doubleand to change each instance of the Convert.
ToInt32 microsoft visual studio 2013 c# tutorial free to Convert. Run your calculator app, and divide the number In the Revise the code section, you reduce the number of decimal places in the results. You've improved your basic calculator microsoft visual studio 2013 c# tutorial free, but your app doesn't yet handle exceptions, such as user input errors. For example, if users try to divide by zero, or enter an unexpected character, the app might stop working, return an error, or return an unexpected nonnumeric result.
Let's walk through a few common user input errors, locate them in the debugger if they appear there, and fix them in the code. For windows 10 free 2019 free information about the debugger and how it works, see First look at the Visual Studio debugger.
If you try to divide a number by zero, the console app might freeze, and then shows you what's wrong in the code editor. Sometimes the app doesn't freeze, and the debugger doesn't show a divide-by-zero error. Instead, the app might return an unexpected nonnumeric result, such as an infinity symbol.
The following code fix still applies. In program. After you replace the code, the section with the switch statement should look similar to the following screenshot:. Now, when you divide any number by zero, the app asks for another number, and keeps asking until you provide a nonzero number. If you enter an alphabetic character when the app expects a numeric character, the app freezes.
Visual Studio shows you what's wrong in the code editor. Rather than rely on the program class to handle all the code, you can divide your app into two classes: Calculator and Program.
The Calculator читать статью handles the bulk of the calculation work, and the Program class handles the user interface and error-handling work.
Follow the prompts and divide the number 42 by the number Your results should look similar to the following screenshot:. You can now enter more equations until you choose to close the console app.
There are also fewer decimal places in the results. And if you enter an incorrect character, you get an appropriate error response. Now that you've created an app, you might want to add it /2171.txt a Git repository. Git is the most widely used modern version control system, so whether you're a professional developer or you're learning how to code, Git can be very useful. There, you can find cheat sheets, a popular online book, and Git Basics videos.
To associate your code with Git, start by creating a microsoft visual studio 2013 c# tutorial free Git repository where your code is located:. The repository name auto-populates based on your folder location. Your new repository is private by default, which means you're the only one who can access it.
Whether your repository is public /12823.txt private, it's best to have a microsoft visual studio 2013 c# tutorial free backup of your code stored securely on GitHub. Even if you aren't working with a team, a remote repository makes your code available to you from any computer. You can use this icon to pull any incoming commits or push any outgoing commits. You can also choose to view these commits first.
The second icon with the pencil shows the number of uncommitted changes to your code. You can select this icon to view those changes in the Git Changes window. To learn more about how to use Git with your app, see the Visual Studio version control documentation. In this tutorial, you made many changes to the calculator app. The app now handles computing resources more efficiently, and handles most user input errors.
