I just need to update the variables of the table each time** z **is less or equal to** n. **That is the only help I need ): because it's printing the same value and I know why but I don't know how to update these variables again. Thanks in advance.

**The testing I use is**

**Loan = 10000**

**Interest = 12**

**Payments in months = 15**

#include <iostream>

#include <cmath>

using namespace std;

int main() {

//Variables

float l, air;

int n, z = 1, count, mainInterest = 100;

double countingBalance, previousBalance, countingPrincipal, counterPrincipal, interestCounter, interestfinal = 6.50, mainPrincipal = 6.21;

//Inputs of the user

cout << "Enter loan amount: " << endl;

cin >> l;

cout << "Enter annual interest rate: " << endl;

cin >> air;

cout << "Enter number of payments in months: " << endl;

cin >> n;

//Calculation

float rate = air / 12.00;

rate = rate / 100;

float monthlyPayment = (rate * pow(1 + rate, n) *l) / (pow(1 + rate, n) -1);

float payment = monthlyPayment * n;

float interestPaid = payment - l;

double principal = monthlyPayment - 100;

double endingBalance = l - principal;

//Output

cout << "Monthly Payment: $" << monthlyPayment << endl;

cout << "Amount paid back: $" << payment << endl;

cout << "Interest paid: $" << interestPaid << endl;

cout << "\n----------------------------------Amortization Schedule----------------------------------------" << endl;

cout << "\tBeginning Balance" << "\tInterest" << "\tPrincipal" << "\tEnding Balance" << endl;

cout << z << "\t $" << l << "\t $100" << "\t $" << principal << "\t $" << endingBalance << endl;

//Updating the table - Variables to update the table

countingPrincipal = principal + mainPrincipal;

countingBalance = l - countingPrincipal;

interestCounter = mainInterest - interestfinal;

previousBalance = countingBalance - principal;

counterPrincipal = principal + mainPrincipal;

while (z <= n) {

count = z++;

cout << z << "\t $" << countingBalance << "\t $" << interestCounter << "\t $" << counterPrincipal << "\t $" << previousBalance << endl;

}

return 0;

}
