Program C ++ untuk Menampilkan Seri Fibonacci

Posted on July 11, 2020 by administrator

Urutan Fibonacci adalah seri di mana istilah berikutnya adalah jumlah dari dua istilah sebelumnya. Dua istilah pertama dari deret Fibonacci adalah 0 diikuti oleh 1.

The Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21

Contoh 1: Seri Fibonacci hingga n jumlah istilah

#include 
using namespace std;

int main()
{
    int n, t1 = 0, t2 = 1, nextTerm = 0;

    cout << "Enter the number of terms: ";
    cin >> n;

    cout << "Fibonacci Series: ";

    for (int i = 1; i <= n; ++i)
    {
        // Prints the first two terms.
        if(i == 1)
        {
            cout << " " << t1;
            continue;
        }
        if(i == 2)
        {
            cout << t2 << " ";
            continue;
        }
        nextTerm = t1 + t2;
        t1 = t2;
        t2 = nextTerm;
        
        cout << nextTerm << " ";
    }
    return 0;
}

Keluaran

Enter the number of terms: 10
Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,

Contoh 2: Program untuk Menghasilkan Urutan Fibonacci Hingga Jumlah Tertentu

#include 
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;
}

Keluaran

Enter a positive integer: 100
Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89,
