the program is doing everything I want it to do but one thing. I want it to accumulate the interest earned per year and to print that number. By that I mean that I want the interest for year one to be printed after year one, and then I want the interest to reset to 0. I want the interest earned to be only for one individual year at a time. My program currently accumulates the interest each consecutive year, so by year 3, the printed interest is the accumulation of interest earned in year 1, 2, and 3.
