java语言程序设计(基础篇)第十版编程练习题[2.13]

(财务应用程序：复利值)假设你每月向银行账户存 100 美元，年利率为 5%, 那么每月利率是0.05/12=0.00417。第一个月之后，账户上的值就变成：
100 * (1 + 0.00417) = 100.417
第二个月之后，账户上的值就变成：
(100 + 100.417) * (1 + 0.00417) = 201.252
第三个月之后，账户上的值就变成：
(100 + 201.252) * (1 + 0.00417) = 302.507
依此类推。
编写程序显示六个月后账户上的钱数。(在编程练习题 5.30中，你将使用循环来简化这里的代码，并能显示任何一个月之后的账户值。)
