Program Listing

#include <iostream>

#include <iomanip>

#include <fstream>

using namespace std;

main() {

    string name;

    int principal=0;

    int number_months=0;

    float rate=0.00,solve_rate=0.00;

    ofstream file("report.txt");

    cout << "\t  Kwarta Agad Lending Investor";

    cout << "\n\n";

    cout << "Enter Customer Name    :=> ";

    getline(cin,name);

    cout << "\nEnter Amount  Loan   :=> ";

    cin >> principal;

    cout << "\nNumber of Months    :=> ";

    cin >> number_months;

    cout << "\nEnter Rate Per Month :=> ";

    cin >> rate;

    solve_rate = (principal * number_months * rate ) ;

    cout << "\n\n";

    cout << fixed << setprecision(2);

    cout << "The Simple Interest Rate is Php "

         << solve_rate << ".";

    file << "\n\t ======= Kwarta Agad Lending Investor =========";

    file << "\n\n";

    file << "\n\t\t CUSTOMER REPORT";

    file << "\n\n";

    file << "\n Customer Name     : " << name;

    file << "\n Amount   Loan     : " << principal;

    file << "\n Number of Months  : " << number_months;

    file << "\n Rate Per Month    : " << rate;

    file << "\n\n";

    file << fixed << setprecision(2);

    file << "\n Interest Rate is Php " << solve_rate;

    file.close();

    cout << "\n\n";

    system("pause");
