int terms, n1=0, n2=1, next;

cout<<"How many terms of Fibonacci series you want to show? ";

cin>>terms;

cout<<"Fibonacci series:"<<endl;

for(int c=1;c<=terms;c++)

{

if(c==1)

{

cout<<n1<<" ";

}

else if(c==2)

{

cout<<n2<<" ";

}

else 

{

next=n1+n2;

    n1=n2;

n2=next;

    cout<<next<<" ";

}

}

    return 0;
