Question

c++ and please add tables and everything and make sure program is complete.

Write a menu driven program, which would compute compound interest and a monthly payment for a loan. The user will be given a choice to display the info on the screen or to a filo Menu will be the following Enter (1) to calculate your loan monthly payment Enter (2) to calculate your loan monthly payment & write to a file Tips: Compound Interest Formula A = P(1+1)" P = principal amount (the initial amount you borrow or deposit) annual rate of interest (as a decimal) t = number of years the amount is deposited or borrowed for A = amount of money accumulated after n years, including interest n = number of times the interest is compounded per year The program will be displaying something like the following: Borrower's Name Borrower's Address: Borrower's Phone Loan Amount: Interest Rate (APR) Fixed Monthly Payment: Note - always with the option to display in a file or on the screen

Answer 1

//do comment if any problem arises

//code should be something like

#include <iostream>

#include <cmath>

#include <string>

#include <fstream>

using namespace std;

//this funciton returns choise of user

int menu()

{

cout << "\nEnter (1) to calculate your loan monthly payment";

cout << "\nEnter (2) to calculate your loan monthly payment & write to a file\n";

int choise;

cin >> choise;

//invalid choise

if (choise != 1 && choise != 2)

return menu();

return choise;

}

//this function caculates monthly payment

double calculate_monthly_payment(double P, double r, int t)

{

double A;

A = P * pow(1 + r, t);

A /= t;

return A / 12;

}

int main()

{

string filename = "output.txt";

ofstream outfile(filename, ios::app);

int choise = menu();

string name, Address, Phone;

//principal amount

double P, fixed_monthly_payment,r;

//interest rate

int t;

//read Borrower's name

cout << "Borrower's Name: ";

cin.ignore();

getline(cin, name);

//read Borrower's address

cout << "Borrower's Address: ";

cin.ignore();

getline(cin, Address);

//read Borrower's phone

cout << "Borrower's Phone number: ";

cin.ignore();

getline(cin, Phone);

cout << "Loan Amount: ";

cin >> P;

//read interest rate

cout << "Interest Rate (APR): ";

cin >> r;

r/=100;

//read number of years

cout << "Number of years the amount is deposited or borrowed for: ";

cin >> t;

fixed_monthly_payment = calculate_monthly_payment(P, r, t);

cout << "Fixed Monthly payment for your loan is: " << fixed_monthly_payment;

if (choise == 2)

{

outfile << "Borrower's Name: " << name << endl;

outfile << "Borrower's Address: " << Address << endl;

outfile << "Borrower's Phone: " << Phone << endl;

outfile << "Loan Amount: " << P << endl;

outfile << "Interest Rate: " << r << endl;

outfile << "Fixed Monthly Payment: " << fixed_monthly_payment << endl;

}

outfile.close();

}

Output:

Enter (1) to calculate your loan monthly payment Enter (2) to calculate your loan monthly payment & write to a file 2 Borrower's Name: Rohit Shetty Borrower's Address: NBJ nagar delhi Borrower's Phone number: 46446xxxxx Loan Amount: 500000 Interest Rate (APR): 6 Number of years the amount is deposited or borrowed for: 1 Fixed Monthly_payment for your loan is: 44166.7

Output file output.txt:
