PROGRAM TO GENERATE FIBONACCI SERIES..

INPUT--

#include <iostream>

using namespace std;

int main()

{

    int t1 = 0, t2 = 1, nextTerm = 0, n;

    cout << "Enter a positive number: ";

    cin >> n;

    // displays the first two terms which is always 0 and 1

    cout << "Fibonacci Series: " << t1 << ", " << t2 << ", ";

    nextTerm = t1 + t2;

    while(nextTerm <= n)

    {

        cout << nextTerm << ", ";

        t1 = t2;

        t2 = nextTerm;

        nextTerm = t1 + t2;

    }

    return 0;

}                        

OUTPUT--

Enter a positive integer: 100

Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89,
