# Even Fibonacci numbers ([link](https://projecteuler.net/problem=2))

> Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

>

> 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

>

> By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

## Use

Type in console:

```

% ./bin/fib 4000000

Sum of all even Fibonacci numbers, that less than 4000000 is 4613732.

% ./bin/fib 999999999

Sum of all even Fibonacci numbers, that less than 999999999 is 350704366.

% ./bin/fib 999999999999

Sum of all even Fibonacci numbers, that less than 999999999999 is 478361013020.

```

## Build
