Enable C 17 Support in VSCode C Extension

Users may encounter errors related to std::string_view in their VSCode C projects, despite successful builds. This issue stems from the C linter or intellisense not recognizing C 17 syntax. To resolve this:

• Open the VSCode extension settings and search for "cppstandard."
• Select the desired C version (e.g., C 17) from the dropdown.

This adjustment only affects the editor's syntax highlighting and code suggestions. To ensure compatibility in the debugging process:

• Modify the tasks.json file, ensuring it includes the following lines:

"args": [
    "-std=c++17",
    # ... remaining arguments
],

and specifies the correct version in the line following:

{
    # ... remaining configuration
    "version": "17"
}

Note that this customization creates an "out" directory in the workspace root.

By following these steps, you can enable C 17 support in the VSCode C Extension, resolving syntax errors and ensuring consistency in both editor and debugging environments.
