Which Of The Following Lines Should Be Inserted To Complete The #1727

Which of the following lines should be inserted to complete the following recursive implementation used to find the length of a linked list?</p> <pre><code class="language-c"> #include<stdio.h> #include<stdlib.h> struct Node { int val; struct Node *next; }*head; int recursive_get_len(struct Node *current_node) { if(current_node == 0) return 0; return _____; } int main() { int arr[10] = {1,2,3,4,5}, n = 5, i; struct Node *temp, *newNode; head = (struct Node*)malloc(sizeof(struct Node)); head->next = 0; temp = head; for(i=0; i<n; i++) { newNode = (struct Node*)malloc(sizeof(struct Node)); newNode->val = arr[i]; newNode->next = 0; temp->next = newNode; temp = temp->next; } int len = recursive_get_len(head->next); printf("%d",len); return 0; }</code></pre>

This multiple choice question (MCQ) is related to the book/course gs gs122 Data Communication and Computer Network. It can also be found in gs gs122 Recursion - Length of a Linked List using Recursion - Quiz No.1.

 #include<stdio.h> #include<stdlib.h> struct Node { int val; struct Node *next; }*head; int recursive_get_len(struct Node *current_node) { if(current_node == 0) return 0; return _____; } int main() { int arr[10] = {1,2,3,4,5}, n = 5, i; struct Node *temp, *newNode; head = (struct Node*)malloc(sizeof(struct Node)); head->next = 0; temp = head; for(i=0; i<n; i++) { newNode = (struct Node*)malloc(sizeof(struct Node)); newNode->val = arr[i]; newNode->next = 0; temp->next = newNode; temp = temp->next; } int len = recursive_get_len(head->next); printf("%d",len); return 0; }
