Write a Program to Find the Nth Term of the Fibonacci Series

C++// C++ Program to Find the // Nth Term of the Fibonacci Series #include <iostream> using namespace std; int fib(int n) { int first = 0, second = 1, ans; if (n == 0) return first; for (int i = 2; i <= n; i++) { ans = first + second; first = second; second = ans; } return ans; } int main() { int n = 13; cout << fib(n); return 0; }

Output
