I need help passing the file from opeFile() to fillQuestionArray()

9:26: warning: unused parameter ‘input’ [-Wunused-parameter]
 void openFile (ifstream& input, const string& message)

You are not openning the file passed as parameter, but a local one.
ifstream in(inputFileName);
you may use the .open() function
http://www.cplusplus.com/reference/fstream/ifstream/open/

cout << "Go into the loop? in peek loop" << endl; // test to see if it even goes into the
                                                  // loop, it does not print it so it never
                                                  // goes in 

you may also use a breakpoint.

	while (in.peek () != EOF)
	{
		//...
		while (line != "$")
		{
			getline (in, line); //¿what if this reading fails?
			questions[index] = questions[index] + "\n" + line;
