C++ Fibonacci Series

Fibonacci series number in the following sequence 0,1,1,2,3,5,8,13,21,......., and so on. Looking more closely we realize that numbers denoted Fₙ, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1.

Let assume A1 is first number of the sequence A1 = 0, A2=1, A3=A1+A2=1,A4=A3+A2=2 and so on.

Now using what we have learned write a program to print the Fibonacci series for the given number of terms.


#include 
using namespace std;

int main() {
    int n, term1 = 0, term2 = 1, next_Term = 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;
        term1 = term2;
        term2 = next_Term;
        
        cout << next_Term << ", ";
    }
    return 0;
}


Output
Enter the number of terms: 5
Fibonacci Series: 0, 1, 1, 2, 3,
