I have a class that processes a file, and as part of the constructor with one argument I want to input a file using fstream.

I basically want it do something like this

class someClass{
   public:
      someClass(char * FILENAME)
      {   
          fstream fileToProcess;
          fileToProcess.open(<FILENAME>, fstream::in | fstream::out | fstream::app);
      }
};

I want to pass the filename in as an argument to the class constructor, and then the class someClass will access it with fstream.
