I am so new at function I am having a great deal of trouble I can write the program and it comes out exactly as it is supposed to so how can I turn this into a function
Code:
#include <iostream>
#include <iomanip>
#include <string>
#include <cmath>
using namespace std;
int main( )
{
const float yearly_int_rate = 0.053;
const float quarterly_int_rate = (0.053/4.0);
double balance;
double new_balance;
double interest_earned;
int quarter;
double first_qt_interest;
double second_qt_interest;
double third_qt_interest;
double fourth_qt_interest;
double first_qt_balance;
double second_qt_balance;
double third_qt_balance;
double fourth_qt_balance;
interest_earned = 0;
new_balance = 0;
balance = 0;
quarter = 0;
first_qt_interest = 0;
second_qt_interest = 0;
third_qt_interest = 0;
fourth_qt_interest = 0;
first_qt_balance = 0;
second_qt_balance = 0;
third_qt_balance = 0;
fourth_qt_balance = 0;
cout << "Enter the account balance and press the Enter key ./n " << endl;
cin >> balance;
first_qt_interest = balance * quarterly_int_rate;
first_qt_balance = balance + first_qt_interest;
second_qt_interest = first_qt_balance * quarterly_int_rate;
second_qt_balance = first_qt_balance + second_qt_interest;
third_qt_interest = second_qt_balance * quarterly_int_rate;
third_qt_balance = second_qt_balance + third_qt_interest;
fourth_qt_interest = third_qt_balance * quarterly_int_rate;
fourth_qt_balance = third_qt_balance + fourth_qt_interest;
cout << fixed << showpoint;
cout << setprecision(2);
cout << "Quarter " << "Balance " << "Interest Earned " <<
"New Balance " << endl;
cout << setw(4) << "1" << setw(9) << "$" << balance << setw(9) << "$"
<< first_qt_interest << setw(10) << "$" << first_qt_balance << endl;
cout << setw(4) << "2" << setw(9) << "$" << first_qt_balance << setw (9) << "$"
<< second_qt_interest << setw(10) << "$" << second_qt_balance << endl;
cout << setw(4) << "3" << setw(9) << "$" << second_qt_balance << setw(9) << "$"
<< third_qt_interest << setw(10) << "$" << third_qt_balance << endl;
cout << setw(4) << "4" << setw(9) << "$" <<third_qt_balance << setw(9)<< "$"
<< fourth_qt_interest << setw(10) << "$" << fourth_qt_balance << endl;
system("pause");
return 0;
}
