```/***************************************************
Compound Interest (Version 1)

Write a program that reads an annual interest rate
from the user, and computes the ammount of money
you'd have after 10 years at that interest rate,
if you made \$100.00 payments into the account at
the beginning of each year.

The formula for interest is this:  If T is the
amount of money in your account at the beginning of
the year, and r is the annual interest rate, the
amount in your account at the end of the year is:

T*(1.0 + r/100.0)

***************************************************/
#include <iostream>
using namespace std;

int main()
{
double r;
cout << "Enter interest rate: ";
cin >> r;

// Compund 10x - Ti is the amount of money in
// your account after year i is finished.
double T1,T2,T3,T4,T5,T6,T7,T8,T9,T10;
T1 = 100.0*(1.0 + r/100.0);
T2 = (T1 + 100.0)*(1.0 + r/100.0);
T3 = (T2 + 100.0)*(1.0 + r/100.0);
T4 = (T3 + 100.0)*(1.0 + r/100.0);
T5 = (T4 + 100.0)*(1.0 + r/100.0);
T6 = (T5 + 100.0)*(1.0 + r/100.0);
T7 = (T6 + 100.0)*(1.0 + r/100.0);
T8 = (T7 + 100.0)*(1.0 + r/100.0);
T9 = (T8 + 100.0)*(1.0 + r/100.0);
T10 = (T9 + 100.0)*(1.0 + r/100.0);

// Write results.
cout << "Final amount is: "
<< T10 << " dollars" << endl;

return 0;
}
