1. ## Need Help with amortization formula

If only it were that easy. His response is try to use the book, search examples on Google etc.
2. ## Need Help with amortization formula

So what I am trying to do is calculate a monthly payment in a while loop that is within the monthly payment range. For example if the monthly payment range is 1240-1250, I need a monthly payment that is within those means. As for m and t, m is supposed to be the number of payments in a year (12) and t is supposed to be the number of years for the loan (30). I can calculate everything except for the monthly payment, I keep getting 0. I also put the break in their just for testing measures. This is what the assignment says:   You program should then use the amortization formula in a loop, repeatedly trying different values for L (loan amount). When the monthly payment computed is below and within \$10 of the desired amount, the loop is finished.   And I can't figure it out.
3. ## Need Help with amortization formula

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 { grossSalary(); interestRate(); monthlyPaymentRange(); maxTarget(); monthlyPayment(); system("pause"); } 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); break; } return R; } I am completely stuck and don't know how to go about it. Any help would be great.
4. ## Best anguage to start Android apps?

Thank you for the links. They were very enlightening.
5. ## Best anguage to start Android apps?

Thank you for all the advice. I would like to take this thread one question further. Knowing that in order to become a game designer(I'm assuming all positions; game programmer, UI designer, etc.) you need to have a portfolio of some sort show casing what you have created. Can mobile games play a part in your portfolio or is that is that a completely different path?
6. ## Best anguage to start Android apps?

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.
7. ## Is there a simpler way of doing this?

Thank you for the help. It does make more sense to use string instead of char now that you guys have explained things, and from now on i will post code snippets instead of screen shots, thanks for the reminder.
8. ## Is there a simpler way of doing this?

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.
9. ## Game Programming Careers?

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.
10. ## Windows Phone MediaElement Help

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.
11. ## Xamarin

I am now aware of a new development environment that is for cross-platform development of mobile phone operating systems called xamarin. It allows you to develop for android, ios, mac, and windows apps using c#. I have an opinion based question; would anyone recommend that you learn the languages separately, such as objective-c for ios, or using the android sdk using java if you want to get into app development, or if you already know c# would you recommend using xamarin and code for apps that way?
12. ## Windows Form Program Problem

A friend of mine helped me out. It was the OpacityKey in the properties that was screwin with my program. Thanks for the help though :)
13. ## Windows Form Program Problem

I also wrote a program on the lecture my teacher was giving but I am not able to submit that as my own program, but I used all the same elements as that program but for some reason this happened to this program and not the one I did with the class and my teacher. This is very strange lol.
14. ## Windows Form Program Problem

Do you think it could be a property of the textboxs themselves? Or the property of the program background? Because when I changed the color of the textboxs I can see what I type but if I click the textbox its still transparent.
15. ## Windows Form Program Problem

On the left is what the program looks like in the designer and on the right I have the program running. As you can tell it is see through and I don't know why. I haven't changed any properties in the designer on any of the elements.     Here is my code. And like I said I haven't completed this yet I just wanted to make sure that there were no errors before I continued. Any ideas? Thanks in advance.
