/*
 (财务应用：计算未来投资值）编写程序，读取投资总额、年利率和年数，然后使用下面的公式 显示未来投资金顛：
未来投资金额 = 投资总额 X (1+ 月利率）年数×12
例如：如果输入的投资金额为1000, 年利率为 3.25%, 年数为1, 那么未来投资额为1032.98。 下面是一个运行示例：
 */
public class NKTest {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter investment amount:");
//        输入投资总额
        double IA = sc.nextDouble();
        System.out.print("Enter annual interest rate in percentage (%):");
//        输入年利率
        double AIRIP = sc.nextDouble() / 100;
        System.out.print("Enter number of years:");
//        输入年数
        int NOY = sc.nextInt();
        sc.close();
//        未来投资金额 = 投资总额 X (1+月利率）^(年数×12) --》 未来投资金额 = 投资总额 X (1+年利率/12）^(年数×12)
        double number = IA * Math.pow(1 + AIRIP/12, NOY * 12);
        System.out.println("Accumulated value is:"+ String.format("%.2f", number));
    }
}
