//Program to show loan and interest calculation
#include <iostream> // for cin, cout

int main()
{
double loan, ann_interest, monthly_payment, interest_rate, interest_paid, rem_bal, total_interest_paid, payment, month_interest=(1/12); //declaration of loan and interest rate
int payment_count=1; //declaration of the payment serial numbers
