if true
  % code
here is the code 
while  balance >0 %checking the balance 
      if balance < monthPay
        balance = balance- balance; %to avoid the value from getting negative
      else
        balance = balance - monthPay;
        interestPaid = (Interest/1000.00)*balance;
        TotalCreditLeft = balance + interestPaid;
        RealPaymentMonthly = monthPay - interestPaid;
        balance = TotalCreditLeft;
      end
        month=month+1;
        TotalInterest = interestPaid + interestPaid;
            fprintf('After month %d ,', month) ;
            fprintf('your balance is   : $ %.2f\n',balance);
            fprintf('Interest Paid         : $ %.2f\n',interestPaid);
            fprintf('Total Debt left       : $ %.2f\n',TotalCreditLeft);
            fprintf('Real Payment Monthly  : $ %.2f\n',RealPaymentMonthly);
          fprintf('\n');
end
