Hi,

I need to create a mortgage calculator program that asks the user to input the loan amount, mortgage term, & interest rate. I am to display the mtge payment amount. I am fine with all of this.

I am then to list the loan balance and interest paid for each pymt over the term of the loan. On longer-term loans, I am not to allow the list to scroll off the screen. I need to display a partial list and then allow the user to continue the list. This is where I am unsure of where to start. I began a for loop, but I don't know if this is in the right direction. I also can't find the formula for calculating the balance. Can anyone point me in the right direction to get started?

Code:#include <iostream> #include <cmath> #include <iomanip> using namespace std; int main() { float LOAN_AMOUNT=0; //loan amt float INT_RATE=0; //interest rate int TERM_YEARS=0; //loan term in years char quit; //determines if user wants to quit do { //output message asking for loan amt cout<<"Input the total loan amount:\n"; //input data cin>>LOAN_AMOUNT; //output message asking for interest rate cout<<"Input the annual interest rate:\n"; //input data cin>>INT_RATE; //output message asking for term in years of loan cout<<"Input the length of the loan in years:\n"; //input data cin>>TERM_YEARS; //local variables float RATE=INT_RATE/100; //rate in decimal format float monthlyInterest; //monthly interest rate int numberOfPayments; //total number of payments float payment; //monthly payment float balance; // loan balance //calculate values monthlyInterest=RATE/12; //monthly interest is rate/12 numberOfPayments=TERM_YEARS*12; //# of pymts is length of loan*12 payment=(LOAN_AMOUNT* pow(monthlyInterest + 1, numberOfPayments) * monthlyInterest)/(pow(monthlyInterest + 1, numberOfPayments) - 1); //pow returns x raised to the power of y //output results cout<<fixed<<setprecision(2)//cout writes text to the screen <<"\n"; cout<<"Your monthly payment for " <<TERM_YEARS <<" years\n"; cout<<"for an Interest Rate of " <<INT_RATE <<"%\n"; cout<<"on a Loan Amount of $" <<LOAN_AMOUNT <<":\n"; cout<<"\n"; cout<<"$" <<payment <<" a month\n"; cout<<"\n"; cout<<"Payment Number\tLoan Balance\tInterest Paid\n"; cout<<"--------------\t------------\t-------------\n"; for (int paymentNumber=1; paymentNumber< ? ; ++paymentNumber) { cout<<paymentNumber<<'\n'; } //user can continue in a loop or quit //output cout<<"\n"; cout<<"Enter C to continue, Q to quit >"; //user input cin>>quit; cout<<"\n"; while((quit!='q') && (quit!='Q') && (quit !='c') && (quit !='C')); } while((quit!='q') && (quit!='Q')); cout<<"Thanks for visiting\n"; }
