Hello everybody, I'm pretty much a beginner at using C, so my problem shouldn't be too difficult for you to solve, I hope. I wrote this program to sum all the even numbers in the fibonacci sequence below 4 million:

When I run this program, it returns "The answer is 0.", and I can't figure out why. Any ideas?Code:#include <stdio.h> int main() { int current = 0; int prev = 1; int prev2 = 0; int sum = 0; do { current += (prev + prev2); prev2 = prev; prev = current; if (current%2==0){ sum += current; } } while (current < 4000000); printf("The answer is %d.", sum); getchar(); return 0; }
