Need Help with amortization formula

02 August 2014 - 11:02 AM

So I currently taking a class in C++ which I find difficult only because I am not so experienced. I was wondering if anyone can help me figure out a while loop to calculate a single monthly payment for this program.

//Amortization Formula: R =        L * i
                            1 - (1 + i)^-mt
#include <iostream>
#include <cmath>
#include <iomanip>

using namespace std;

double R; // amortization formula
double L = 0.00; // loan amount (principal)
double g; // gross salary
double r; // interest rate per year
int t = 30; // number of years for the loan
int m = 12; // number of payments in a year
double i = m / t;
int p; // monthly payment range

int grossSalary(); // prototype function of grossSalary
double interestRate(); // prototype function of interestRate
double monthlyPaymentRange(); // prototype function of monthlyPaymentRange
double maxTarget(); // prototype function of maxTarget
double monthlyPayment(); // prototype function of monthlyPayment

int main() // this combines all of the functions in order to give the monthly payment

int grossSalary() // this function asks for the gross salary of the user and returns g (gross salary)
	cout << "Please enter your yearly gross salary: ";
	cin >> g;
	return g;

double interestRate() // this function asks the user for an interest rate and returns r (interest rate)
	cout << "Please enter an interest rate: ";
	cin >> r;
	return r;

double monthlyPaymentRange() // this function calculates the monthly payment range
	p = g / 12 * 0.3;
	cout << "The target (30% of monthly salary) monthly payment range is: " << p << endl;
	return p;

double maxTarget() // this function calculates the maximum target house price
	L = g * r - g;
	cout << "Your max target house price is: " << L << endl;
	return L;

double monthlyPayment() // this function calculates the monthly payment using the amortization formula
	cout << "with a monthly payment of: " << R << endl;
	while(L < p) // how to fix this?
		cout << R << endl;
		R = L * i / 1 - pow(1 + i, -m * t);
	return R;

I am completely stuck and don't know how to go about it. Any help would be great.

Best anguage to start Android apps?

06 November 2013 - 10:47 AM

Hello all, I was wondering what language is the best to develop Android games, and apps in? I was previously attempting to create a "Hello World" app in Java using Eclipse and the Android SDK, but I have recently found that I can write apps in C++. Is this true, and if so would anyone recommend to do so in C++, as well as how I would go about using an SDK for Android in C++? I am also currently a college student and will be needing to take C++ as a requirement for the degree I am pursuing, but I will also need to take Java as an elective closer to the time of my graduation. That is just a little background as to which way you might lean towards when replying to this thread.


Thanks in advance.

Is there a simpler way of doing this?

28 July 2013 - 11:58 PM

I am new to c++ and this is my first c++ program. I am experimenting with little things, but is there any simpler way of writing this code, and by writing this code is there some way I can use length for both char * c and char * x? Thanks for your help in advance.


Game Programming Careers?

12 June 2013 - 01:21 AM

I was wondering what the different types of game programming careers are out there in the industry. I know some, physics programmer, engine programmer, graphics programmer, and AI programmers to name a few, but what more are there and which are the least tedious when it comes to coding? I am just curious as to what's out there as I am trying to begin now during the summer on programming specifically for games before I head into college on my way to earn a bachelors degree in computer science. Thanks in advance.

Windows Phone MediaElement Help

21 March 2013 - 08:39 PM

Does anyone here code for the windows phone. I am using windows phone 7 (I know its outdated) for a school assignment. I was wondering if anyone knows how to make the MediaElement work. This is what I have and I don't see anything when I run the app. I have also tried using tutorials in order to figure this out as well but none of the tutorial I have followed have worked either. Help would be much appreciated. Thank You in advance.
