I’m encountering an issue where Prettier automatically reformats my C++ macros into a single line, even though I’ve tried using the // prettier-ignore directive. Here’s an example of my code:

`// Expected formatting
#define vo(a)             
    for (auto x : a)      
    {                     
        cout << x << " "; 
    }                     
    cout << endl;`

However, Prettier reformats it into a single line:

#define vo(a) for(auto x:a){cout<<x<<" ";}cout<<endl;

What I’ve Tried:

1. Placing // prettier-ignore before the macro definition.
2. Checking my Prettier configuration file (.prettierrc) for any settings that might override the ignore directive.
3. Using a .prettierignore file to exclude the specific file.
   Despite these efforts, Prettier continues to reformat the macro. I want to preserve the multi-line structure for readability and maintainability.

Questions:

1. How can I prevent Prettier from reformatting my C++ macros into a single line?
2. Is there a configuration or setting in Prettier or my editor that I might miss?
