Answer 1

Answer:

int main() {

   int i=1, n, t1 = 0 , t2 = 1 , nextTerm;

   scanf("%d", &n);

   

   if(n==1 || n==0){

       printf("%d", n);

   }else {

       nextTerm = t1 + t2;

   }

   

   for ( i=3; i<=n; ++i){

       t1 = t2;

       t2 = nextTerm;

       nextTerm = t1 + t2;

   }

   printf("%d", t2);

   

   return 0;

}
