C Project: Data Structure Library - Code Example

Example

#include <stdio.h>
#include <stdlib.h>

// Linked List Node
typedef struct Node {
    int data;
    struct Node *next;
} Node;

Node* createNode(int data) {
    Node *node = (Node*)malloc(sizeof(Node));
    node->data = data;
    node->next = NULL;
    return node;
}

void printList(Node *head) {
    while (head != NULL) {
        printf("%d -> ", head->data);
        head = head->next;
    }
    printf("NULL\n");
}

int main() {
    Node *head = createNode(1);
    head->next = createNode(2);
    head->next->next = createNode(3);
    printList(head);
    return 0;
}
