Write a program to calculate fibonacci series


C++ Practical



#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
