Project Euler problem 2

#include <iostream>

int main (int argc, const char * argv[])
{
    int fibone = 1;
    int fibtwo = 2;
    int temp;
   int answer = 0;

    while(fibtwo<4000000){
        temp = fibtwo;
        fibtwo = fibone + fibtwo;
        fibone = temp;
        if(fibtwo%2==0){
            answer +=fibtwo;
        }
    }

    // We add 2 because 2 isn't counted (it gets changed before it can be added)
    std::cout << answer + 2;
    return 0;
}
