// Exercise 8.16: SavingsCalculator.cpp
// Application that calculates the amount of money the user will have
// after one year of saving $100 a month, plus an initial deposit.
#include <iostream> // required to perform C++ stream I/O
#include <iomanip>  // required for parameterized stream manipulators
#include <cmath>    // required to use the C++ math library functions

using namespace std; // for accessing C++ Standard Library members

// function main begins program execution
int main()
{
   // define variables
   double deposit; // stores the initial deposit

   // get input
   cout << "\nEnter the initial value: ";
   cin >> deposit;

   // display floating-point value as currency
   cout << fixed << setprecision( 2 );

   // for loop to calculate interest at different rates
   for ( int counter = 1; counter < 12; counter++ )
   {
      deposit += 100;
   } // end for

   cout << "\nAmount after one year: $" << deposit << endl << endl;

   return 0; // indicate that program ended successfully

} // end function main
