Data structure implementation with Linked lists.

+0
−3

Could someone explain this part of the coding for data structures & linked list? I actually got this code from a textbook but no matter how I read the textbook, I still don't get the concept & what it means. Thanks :")

#include<stdio.h>
#include<stdlib.h>
struct listNode{
    char data;
    struct listNode *nextPtr
};

typedef struct listNode ListNode;
typedef ListNode *ListNodePtr;

void insert(ListNodePtr *sPtr, char value);
char delete(ListNodePtr *sPtr, char value);
int isEmpty(ListNodePtr sPtr);
void printList(ListNodePtr currentPtr);
void instructions(void);

int main (void){
    //some coding
}`

Before trying to understand the code, it would be better to understand the concept. Example: https://www.geeksforgeeks.org/linked-list-set-1-introduction/

This code is simply defining the list's structure and the functions that will manipulate it. What exactly you didn't understand?
