我想出的是： 付款=（费率*（1.0 +费率）* pow（已付款））/（（1.0 +费率）* pow（已付款）-1.0）*贷款
它告诉我“没有重载函数pow的实例匹配参数列表。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;
