| == Write a program that gets a starting principal(A, 원금), annual interest rate(r, 연이율) from a keyboard (standard input) and print the total amount on deposit (예치기간이 지난 뒤 총금액, 원리합계) for the year(n) from 0 to 10. ==
| |
| | |
| total deposit = A*(1+r)^n
| |
| | |
| For example,
| |
| | |
| 1000.0 0.05 <- keyboard input // 5% should be written as 0.05
| |
| 0 1000.00
