Configuring VSCode C Extension for C 17 Support

You may encounter IntelliSense errors with std::string_view in Visual Studio Code (VSCode) despite successfully building your code. This indicates the need to enable C 17 support. This article provides guidance on how to accomplish this.

Solution

• Update VSCode Settings: Navigate to VSCode Extension Settings and search for "cppstandard." Select the desired C version (e.g., C 17) from the drop-down menu.
• Configure Debugger Settings: Ensure that your tasks.json file aligns with the chosen C version. Edit tasks.json and add the necessary lines:

"--std=c++17"
"$gcc -std=c++17"

• Create Output Directory (Optional): If copying the provided tasks.json, ensure you have an "out" folder in your workspace root.

With these settings in place, VSCode will utilize C 17 for both IntelliSense and debugging.
