 Contract: get_file_contents : double[] int char* -> bool
 Purpose: try to open file <infile_name> for reading,
          and try to read its first <desired_size>
          values into array <contents>. Return true if succeeded,
          and false if failed.

 Examples: if const int NUM_SCORES = 4; and
              double scores[NUM_SCORES]; and
              file scores.txt contains:
90
80.5
85.5
99
 
           then if the user runs 
           get_file_contents(scores, NUM_SCORES, "scores.txt")
           then, the array scores will now have the contents
	   {90, 80.5, 85.5, 99}
