Guess it is need + 1 ... to be tested:

 //catch source / destination too high
  if((parsed.destination == 'c' && ((parsed.destination_index >= COLUMN_COUNT + 1) || (parsed.destination_index < 1)))
      || (parsed.destination == 'f' && ((parsed.destination_index >= FOUNDATION_COUNT + 1) || (parsed.destination_index < 1))))
  {
    return MOVE_INVALID_DESTINATION;
  }

  // source_index can also be broken
  if(parsed.source == 'c' && ((parsed.source_index >= COLUMN_COUNT + 1) || (parsed.source_index < 1))){
    return MOVE_INVALID_SOURCE;
  }

Add quit and high score; future may add high score to file, read it then launch the game.

But ending the game seems break the command line. You can still make, ./s to launch but cannot see it.
