// Summing a strange series

/* 
-------------Problem------------
Dr. I. J. Matrix, the mathemagician,
wishes see what happens as the following series of
terms is added up:
	1
	-1/2
	+1/3
	-1/4
	+1/5
	-1/6
and so on until
	-1/20

The first 6 lines of output should look like this:
   n           Term            Sum
   1              1              1
   2            0.5            0.5
   3       0.333333       0.833333
   4           0.25       0.583333

We have the algorithm and you have to code it it in C++.

DATA REQUIREMENTS
  Constants
	None
  Inputs
	None
  Outputs
     A header for the table
     20 lines of the table each having
	n(int) -- The number of the term
	term(float)  -- n'th term in series
	sum(float) --  The partial sums of the series
  Additional
	sign(float) = either +1 or -1.  Sign of n'th term in series.
FORMULAE/FACTS
	Each term in the series is a sign divided by n.
	The Sign of the first term is +1
	Sign is reversed or negated for each term
	We sum the series by adding each term, in turn, into sum,
	starting with sum=0

INITIAL ALGORITHM
	1. sum = 0
	2. sign = +1
	3. Display a header for the table
	4. For n=1,2,3,4,...20 do
		4.1 term = sign/n
		4.2 add term to sum
		4.3 negate the sign
		4.4 Display n, term, and sum
