How to Change the C Language Standard in VS Code with CodeRunner?

Changing C Language Standard in VS Code with CodeRunner

Visual Studio Code defaults to C 98 for execution when using the CodeRunner extension. However, you can easily switch to a different C language standard, such as C 17 or C 20.

Solution:

1. Open the Extensions panel in VS Code.
2. Search for "ms-vscode.cpptools" and click on the C/C extension.
3. Click on the gear icon next to "Uninstall."
4. Select "Extension Settings" from the dropdown menu.
5. Locate the search bar and type "cppStandard."
6. Change the value of "Cpp Standard" to the desired version, such as "c 17" or "c 20."

Once you make the adjustment, the C files will be executed using the selected language standard. To verify, you can include the following code in a C file:

#include <iostream>

int main() {
  if constexpr (sizeof(int) == 4) // C++11 feature
    std::cout <p>With C  17 selected, the code will correctly output that "int is 32 bits," confirming the change in language standard.</p></iostream>
