贷款计算程序的伪代码

Question

设计一个程序，使用户可以查看利率及其各自每月付款的几种选择。该程序必须能够提示贷款金额及其期限（以年为单位）。然后，它将显示每个利率的月度付款和总付款，从3.50％到8.00％，以0.25为增量。必须使用以下公式进行计算：

P =（r * A）/（1 –（1 + r）–N）

哪里

P =每月付款

A =贷款金额

r =利率（r =（年利率/ 100）/ 12）

N =付款次数（N =年数* 12）

总付款额= P x N

用伪代码编写算法。

我已经创建了伪代码，但是我不确定是否有任何错误或错过的任何内容。

1.0 START    
2.0 Set Float rate = 3.5
3.0 Set Int loan_amount = 0
4.0 Set Int year = 0
5.0 Set Int N = year*12
6.0 Set Float P = 0
7.0 Set Float Total_Payment = 0
8.0 Input loan_amount
9.0 Input year
10.0 Add a header "Annual Interest Rate" to the output
11.0 Add a header "Monthly Payment (RM)" to the output
12.0 Add a header "Total Payment" to the output
13.0 Insert a new line
14.0 While (rate<8.0)
15.0 Start
    15.1 Calculate P=(rate*loan_amount)/(1-(1+rate)–N)
    15.2 Calculate Total_Payment = P*N
    15.3 Print rate to header "Annual Interest Rate"
    15.4 Print P to header "Monthly Payment (RM)"
    15.5 Print Total_Payment to header "Total Payment"
    15.6 Insert a new line
    15.7 Set Total_Payment to 0
    15.8 Set P = 0
    15.9 Increase rate by 0.25
16.0 End While
17.0 END
