Insert the following function.
Open this file: CIS022_S2017_Assignment6.txt
Insert the function in your code module above the main() function.
The Files Info is Right here:
void CalculateMonthlyPayment(float LoanAmount, float AnnualInterestRate, int NumberOfPayments, int Payments)
{
// calculates the monthly payment using
// LoanAmount, AnnualInterestRate, and
// NumberOfPayments
float MonthlyInterestRate = AnnualInterestRate / 12 / 100; // convert to monthly interest rate
// P = L * i^n * i
// -------------
// i^n - 1
Payments = (LoanAmount * pow(1 + MonthlyInterestRate, NumberOfPayments) *
MonthlyInterestRate) /
pow(1 + MonthlyInterestRate, NumberOfPayments) - 1;
}

Hint: Hard code values for loan amount, interest rate, and number of payments at first. Use variable values after you get your program working. 4. Correct the function.
I'll help you out. There's 1 syntax error, one logic error in the calculation, and no trapping for out-of-bounds input.
Find them.
Fix them. 5. Insert your program documentation and code comments.
Just as you would do with any other project, insert your program documentation at the top and your code comments in your main() function.
Also, indicate with code comments where you made changes to the given function.
Explanation / Answer
#include <iostream>
#include <math.h>
void CalculateMonthlyPayment(float, float, int, float);
using namespace std;
int main()
{
cout << "Hello World" << endl;
int NumberOfPayments=2;
float Payments=5;
float LoanAmount=1000;
float AnnualInterestRate=40;
CalculateMonthlyPayment(LoanAmount,AnnualInterestRate,NumberOfPayments,Payments);
}
void CalculateMonthlyPayment(float LoanAmount, float AnnualInterestRate, int NumberOfPayments,float Payments)
{
// calculates the monthly payment using
// LoanAmount, AnnualInterestRate, and
// NumberOfPayments
float MonthlyInterestRate = (AnnualInterestRate / 12) / 100; // convert to monthly interest rate
cout<<MonthlyInterestRate<<" ";
// P = L * i^n * i
// -------------
// i^n - 1
cout<<" "<<(pow(1+ MonthlyInterestRate, NumberOfPayments));
Payments = (LoanAmount * (pow(1+ MonthlyInterestRate, NumberOfPayments)) *
MonthlyInterestRate) /
pow( MonthlyInterestRate, NumberOfPayments) - 1;
cout<<"Payment = "<<Payments;
}
/* The only change I did was to change the parameter from int to float. Coming to logical error it all depends on the formaula to be applied. It is not clear here which formula is applied here the only logical error that can occur is not placing the brackets at right places and the result coming to be wrong */
/*Evrything else is fine */
