Answer 1

#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;

}
