 void main()
  {
   int i,no, first=0, second=1, next;
   clrscr();
   first=0;
   second=1;
   printf("Enter nubmer of terms for Series: ");
   scanf("%d",&no);
   printf("Fibonacci series are:\n");
   for(i=0; i<no; i++)
    {
    printf("%d\n",first);
    next = first + second;
    first = second;
    second = next;
   }
   getch();
}

Output

Enter nubmer of terms for Series: 7
Fibonacci series are:
