    #include<iostream>  
    using namespace std;    
    void printFibonacci(int n){  
        static int n1=1, n2=1, n3;  
        if(n>0){  
             n3 = n1 + n2;  
             n1 = n2;  
             n2 = n3;  
     cout<<n3<<" ";  
             printFibonacci(n-1);  
        }  
    }  
    int main(){  
        int n;  
        cout<<"Enter the number of elements: ";  
        cin>>n;  
        cout<<"Fibonacci Series: ";  
        cout<<"1 "<<"1 ";
        printFibonacci(n-2); //n-2 because 2 numbers are already printed  
         return 0;
    }

output:

input:8

The Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, 21…… starts with two 1s, and each term afterward is the sum of its two predecessors. Please write a function, Fib(n), which takes n as the input parameter. It will return the n-th number in the Fibonacci sequence. Using R, the output for Fib(9) should give only the 9th element in the sequence and not any of the previous elements. Please Help :)
