Fibonacci sequence whose values do not exceed four million

Excercise in C: Fibonacci Sequence

Problem:

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.

 

output is 4613732

{
three = one + two;
if (two % 2 == 0)
total += two;
one = two;
two = three;
