How to Configure VS Code for C 14/C 17 Development?

How to Setup VS Code For C 14 /C 17

To set up Visual Studio Code (VS Code) for C 14 or C 17, follow these steps:

1. Install the C Extension

Install the "C/C " extension from the VS Code Marketplace. This extension provides basic C support, including syntax highlighting and code completion.

2. Add the C Compiler

VS Code requires a C compiler to build and run C code. Install a C compiler, such as MinGW or Clang, and add it to your path.

3. Configure the C Compiler in VS Code

In VS Code, open the "Settings" tab and search for "C/C : Compiler Path." Set this setting to the path of the C compiler you installed.

4. Set the C Standard

In the "Settings" tab, search for "C/C : C Standard." Select the C standard you want to use, such as "c 14" or "c 17."

5. Use the Code Runner Extension (Optional)

The Code Runner extension simplifies running C code from VS Code. Install this extension and add the following code to your "settings.json" file:

"code-runner.executorMap": {
    "cpp": "cd $dir && g++ -std=c++17 $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt"
}

Troubleshooting Error: "expected unqualified-id before 'using'"

If you encounter this error while trying to run a C file with C 14 or C 17 syntax, you need to ensure that the C standard is correctly set in your VS Code settings. Follow the steps in section 3 to verify the C standard setting.

If the error persists, try using the Code Runner extension and the settings provided in section 5. This method may bypass the issue and allow you to run your C code.
