Shouldn't line 4 should read while(f[0] <= 4e6) ?

Your code yields the right answer for an input of 4 million, but consider the fibonacci numbers not exceeding 8.

Even fibonaccis would be 2 and 8, resulting in a sum of 10. Your code would log 2 as the answer.

Technically yes, but this is only a problem if the bound is a Fibonacci number itself. In your example, 8 was a Fibonacci number so it got excluded from the sum, but 4,000,000 isn't so the answer will still be right.
