Final recursion,
n = 0
, and the
if
statement does nothing, ending the recursive calls:
if
(0 >= 1)
// condition false
{
// this clause is skipped
}
The
output is
3 2 1

A savings account typically accrues savings using compound interest. If you
deposit $1,000 with a 10% interest rate per year, then after one year you have a
total of $1,100. If you leave this money in the account for another year at 10%
interest, then after two years the total will be $1,210. After three years you would
have $1,331, and so on.
