Course project

For my project, I have chosen the financial calculator. This program will take input from the user such as interest rate, length of loan, amount borrowed, or desired payment and calculate the loan information. Once the information has been calculated, it will display that information for the user. The input information and calculations will be able to be saved for later retrieval.

Input Processes Output

Interest rate amount borrowed * interest rate loan total

Loan length amount borrowed + interest monthly payment

Amount borrowed calculate length of loan number of payments

Desired payment calculate loan number of payments amount borrowed

C++ Code Week 2

#include < iostream >

#include <string> #include < cmath > #include <iomanip> using namespace std;

int main()

{

//Variables

double lengthOfLoan, amountOfLoan, interestRate, monthlyPayment, loanTotal,

totalInterest; //Program

cout << “Welcome to the loan Calculator!\n”

<< “You will be asked to enter the amount of your loan,\n”

<< “the interest rate, and lenth you would like your loan for.\n”

<< “The program will then tell you your monthly payment.\n\n”; cout << “Please enter the loan amount: $"; cin » amountOfLoan;

cout << “Please enter the interest rate: “; cin » interestRate;

cout << “Please enter the length of the loan in months: “; cin » lengthOfLoan; //Calculations

totalInterest = amountOfLoan * interestRate; loanTotal = (amountOfLoan + totalInterest); monthlyPayment = loanTotal / lengthOfLoan;

//Display monthly payment

cout << fixed << setprecision(2);

cout << “Your monthly payment is: $” << monthlyPayment<<"\n”; system(“pause”) ; return 0;
