请用C语言写出链表储存定义

Sure, here's an example C code for defining and storing data in a singly linked list:

// Define the structure for the linked list node
typedef struct Node {
    int data;            // data to be stored in the node
    struct Node* next;   // pointer to the next node in the list
} Node;

// Create a new node with given data and return a pointer to it
Node* createNode(int data) {
    Node* newNode = (Node*)malloc(sizeof(Node));   // allocate memory dynamically for the new node
    newNode->data = data;                           // set the data value
    newNode->next = NULL;                           // set the next node pointer to NULL
    return newNode;
}

// Example usage: create a linked list with 3 nodes storing values 1, 2, 3
int main() {
    Node* head = createNode(1);     // create the head node with value 1
    head->next = createNode(2);     // add a second node with value 2
    head->next->next = createNode(3);  // add a third node with value 3
    return 0;
}

This is just a simple example, and there are many variations on how linked lists can be defined and used in C programs depending on requirements.
