Visual Studio Code Cpp



Visual studio code will use the command as below g directory/main.cpp -o directory/main.out -g -Wall -fcolor- diagnostics -std=c11 this command will raise 'Undefined symbols for architecture x8664' error I can fix it with this new command g main.cpp a.cpp -o main.out. Open Visual Studio 2019. If the start window is not open, choose File Start Window. On the start window, choose Create a new project. On the Create a new project window, enter or type console in the search box. Next, choose C from the Language list, and then choose Windows from the Platform list. After you apply the language and platform filters, choose the Console App template,.

C++ is a statically-typed, free-form, (usually) compiled, multi-paradigm, intermediate-level general-purpose middle-level programming language.

In simple terms, C++ is a sophisticated, efficient, general-purpose programming language based on C.

It was developed by Bjarne Stroustrup in 1979.

One of C++'s main features is the compiler. This is used to compile and run C++ code.

A compiler is a special program that processes statements written in a particular programming language like C++ and turns them into machine language or 'code' that a computer's processor uses.

I actually wrote this article because I had a C++ assignment which required using a compiler. As usual, everyone was using the CodeBlocks IDE and Visual Studio IDE. But I was already used to Visual Studio Code for all my programming stuff.

I then set out to find a way of compiling C++ directly inside my own VsCode Editor, hence this article :).

In this article, I'll show you how to set up your compiler in VsCode and give you some links to some of the best C++ resources.

  • Prior knowledge of C++
    (I assume you're learning C++, about to start learning, or just reading this for fun. This article is not a C++ 101 tutorial – some understanding of C++ is needed.)
  • Visual Studio Code Editor
    Download here and read the setup docs for Windows, Linux and Mac
  • Internet connection (!important)

Disclaimer!

I will be using a Windows OS throughout this article, but I'll provide links to resources that will help those using other operating systems.

Now let's get started!

  • Head to www.mingw.org and click the “Download/Installer” link to download the MinGW setup file, or click here for Windows, here for Linux, and here for Mac
MinGW, a contraction of 'Minimalist GNU for Windows', is a minimalist development environment for native Microsoft Windows applications.
  • After downloading, install MinGW and wait for the “MinGW Installation Manager” to show up.
  • When the “MinGW Installation Manager” shows up, click on mingw32-gcc-g++ then select “Mark for Installation”
  • In the menu at the top left corner, click on “Installation > Apply Changes”
  • Wait and allow to install completely. Ensure you have a stable internet connection during this process.

PATH is an environment variable on Unix-like operating systems, DOS, OS/2, and Microsoft Windows, specifying a set of directories where executable programs are located. In general, each executing process or user session has its own PATH setting. - Wikipedia

After installing MinGW, it can be found in C:MinGWbin. Now you have to include this directory in your environment variable PATH. If you've been using computers for a while now you should know how to do this already, but if you don't, here are a few resources:

  • Click here for a Windows OS guide
  • Click here for Linux
  • Click here for a Mac OS guide

Now we have our compiler set up, let's install Code Runner

Code Runner allows you to Run code snippet or code file for multiple languages:

C, C++, Java, JavaScript, PHP, Python, Perl, Perl 6, Ruby, Go, Lua, Groovy, PowerShell, BAT/CMD, BASH/SH, F# Script, F# (.NET Core), C# Script, C# (.NET Core), VBScript, TypeScript, CoffeeScript, Scala, Swift, Julia, Crystal, OCaml Script, R, AppleScript, Elixir, Visual Basic .NET, Clojure, Haxe, Objective-C, Rust, Racket, AutoHotkey, AutoIt, Kotlin, Dart, Free Pascal, Haskell, Nim, D, Lisp, Kit, and custom command.
  • Click here to download
  • Or search in VsCode marketplace tab
  • After installing restart VsCode
  • Open your C++ file in Vscode. Here's a basic hello world program below:
Visual

Save this file as test.cpp

  • Use the shortcut Ctrl+Alt+N
  • Or press F1 and then select/type Run Code
  • Or right-click the Text Editor and then click Run Code in the editor context menu

The code will run and the output will be shown in the Output Window. Open the output window with `Ctrl+ shortcut.

  • Use the shortcut Ctrl+Alt+M
  • Or press F1 and then select/type Stop Code Run
  • Or right-click the Output Channel and then click Stop Code Run in the context menu

Hurray, you just successfully set up your C++ environment in VsCode!

Here's a quick hint: By default, VsCode's output terminal is read-only. If you're running code that requires user input like:

you won't be able to type into the terminal, Cannot edit in read-only terminal.
To fix this, you need to manually enable read-write.

  • In VsCode, Go to File > Preference > Setting.
  • In the User tab on the left panel, find the extensions section
  • Scroll and find 'Run Code Configuration'
  • Scroll and find a checkbox Run in Terminal (Whether to run code in Integrated Terminal) Check the box.

OR

  • In your setting.json file, add:

Hurray, you're done and ready to roll :).

Here are some C++ resources you can use to get started with learning C++

The C/C++ Code Analysis tool provides information about possible defects in your C/C++ source code. Common coding errors reported by the tool include buffer overruns, uninitialized memory, null pointer dereferences, and memory and resource leaks. The tool can also run checks against the C++ Core Guidelines.

Visual Studio Code Cppdbg

IDE (integrated development environment) integration

The code analysis tool is fully integrated within the Visual Studio IDE.

During the build process, any warnings generated for the source code appear in the Error List. You can navigate to source code that caused the warning, and you can view additional information about the cause and possible solutions of the issue.

Command line support

You can also use the analysis tool from the command line, as shown in the following example:

Visual Studio 2017 version 15.7 and later: You can run the tool from the command line with any build system including CMake.

#pragma support

You can use the #pragma directive to treat warnings as errors; enable or disable warnings, and suppress warnings for individual lines of code. For more information, see Pragma directives and the __pragma and _Pragma keywords.

Visual Studio Code C++ Formatter

Annotation support

Visual Studio Code Cpp

Annotations improve the accuracy of the code analysis. Annotations provide additional information about pre- and post- conditions on function parameters and return types. For more information, see Using SAL Annotations to Reduce C/C++ Code Defects.

Run analysis tool as part of check-in policy

You might want to require that all source code check-ins satisfy certain policies. In particular, you want to make sure that analysis was run as a step of the most recent local build. For more information about enabling a code analysis check-in policy, see Creating and Using Code Analysis Check-In Policies.

Team Build integration

You can use the integrated features of the build system to run code analysis tool as a step of the Azure DevOps build process. For more information, see Azure Pipelines.
