C++

xxxxxxxxxx
 
#include <iostream>
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;
}

Output result

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

#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;
    }

}

Output result

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