The purpose of this assignment is to write a program that requests the user to

enter the data per year, and that computes the EWMA of the growth rates. It

then should use the EWMA to predict the GNI for the next three years.

The actual growth rate can only be computed from the second year on. The

growth rate for the second year will also be the estimated growth rate for the

third year. Only from the third year on can Equation (2) be used to compute

estimates for the next year.

Let gni prev be the GNI of the previous year, rate prev the actual rate

of the previous year, and rate est the current estimate of the growth rate. If

the user enters a GNI gni current for the current year, then you can compute

the rate for the current year, rate current, and the new estimate, rate est,

as follows:

rate_current = (gni_current-gni_prev)/gni_prev ;

rate_est = LAMBDA * rate_current + (1 - LAMBDA) * rate_est;

Once the rate and estimate have been computed, proceed with the next year,

and store the current GNI as the GNI of the (now) previous year.
