我如何在 C++ 中编写这个等式 [关闭]

Question

我想出的是： 付款 = (rate * (1.0 + rate) * pow(madepayments)) / ((1.0 + rate) * pow(madepayments) -1.0) * loan

它告诉我“没有重载函数 pow 的实例与参数列表匹配。参数类型：double

代码：

double rate, payment, loan, madepayments, name, paidback,interestpaid;    

cout << "Enter the loan amount: "; 
cin >> loan; 
cout << "Enter the annual interest rate: "; 
cin >> rate; 
cout << "Enter the number of payments made: "; 
cin >> madepayments; 
cout << "Enter the customer's name: "; 
cin >> name; 
payment = (rate * (1.0 + rate) * pow(madepayments)) / ((1.0 + rate) * pow(madepayments) - 1.0) * loan;

Answer 1

Pow 需要另一个参数来描述指数。
