using System;
class Example {
public static void Main() {
decimal amount;
decimal rate_of_return;
int years, i;
amount = 100000.0M;
rate_of_return = 0.17M;
years = 100;
Console.WriteLine("Original investment: $" + amount);
Console.WriteLine("Rate of return: " + rate_of_return);
Console.WriteLine("Over " + years + " years");
for(i = 0; i < years; i++) {
amount = amount + (amount * rate_of_return);
}
Console.WriteLine("Future value is $" + amount);
}
}
Original investment: $100000.0
Rate of return: 0.17
Over 100 years
Future value is $658546088583.68156535520269753
