Describe how you would code a Fibonacci series (not actually unexpected, pretty standard)

Question

Sigiloso · Accepted Answer

The trick is to ask how many terms you need; the series is recursive so you need to show that you realize that certain ways of doing it will eat huge amounts of processor power.

Sigiloso · Answer

cout> n;
    int firstterm = 0, secondterm = 1;
    cout << firstterm << "," << secondterm << ",";
    int nextterm = firstterm + secondterm;
    for(int i = 1; i < n - 1; i++) 
    {
        cout << nextterm << ",";
        firstterm = secondterm;
        secondterm = nextterm;
        nextterm = firstterm + secondterm;
}
