c - Multiple character comparisons, how can I write it smarter? -

When I am parsing a text file, I will type some characters (space, line break, comma, duration).

I want to leave. In PHP, anyone can check the variable present in an array with in array, but we are working with indicators clearly distinct.

Currently writing it like this (excuse strange formatting)

  if (c == '' || c == '\ n' || c == '.' 'C ==', ') {Continue; }  

But it seems a bit dumb. Is this a clever / more compact way to compare many in this way?
