//  filepos.cpp
//  This program prompts the user for a file name, then prompts for the
//  position (0, 1, 2, ...) of any character in the file.  It then
//  displays the character found at that position and prompts the user
//  for another position.  This continues until the user types a
//  negative number for the position.  If the specified position is
//  greater than the size of the file, the results are undefined.
