Write a program to calculate fibonacci series

#include <iostream>  

using namespace std;  

int main() {  

  int n1=0,n2=1,n3,i,number;    

 cout<<"Enter the number of elements: ";    

 cin>>number;    

 cout<<n1<<" "<<n2<<" "; //printing 0 and 1    

 for(i=2;i<number;++i) //loop starts from 2 because 0 and 1 are already printed    

 {    

  n3=n1+n2;    

  cout<<n3<<" ";    

  n1=n2;    

  n2=n3;    

 }    

   return 0;  

   }  

Output:

Enter the number of elements: 20 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181
