C 组链表(抽象数据类型)

Question

我正在尝试编写一个抽象数据类型来表示使用链表的整数项目集。

我收到以下错误：

ERROR undeclared identifier 'linkedListSet'
error #2152: Unknown field 'code' of '(incomplete) struct LinkedListSet'.

并觉得我必须用函数、结构和指针打破一些基本规则，但我真的想不通。下面是我的代码，其中注释了错误消息行。

#include<stdio.h>
#include<stdlib.h>
struct linkedListElement{
    int data;
    struct linkedListElement * next;
};
struct linkedListSet {
    //struct linkedListElement * firstElement;
    struct linkedListElement * header;
    struct linkedListElement * current;
    struct linkedListElement * temp;
    int code;
};
struct linkedListSet * createdSet (){
    struct linkedListSet * newSet = malloc(sizeof(linkedListSet));
    //ERROR undeclared identifier 'linkedListSet'
    newSet->header->data = 0;
    newSet->header->next = NULL;
    return newSet;
}
int addItem (struct LinkedListSet * setPtr, int info){
    struct linkedListElement * newElementPtr;
    setPtr->code = 3;
    //error #2152: Unknown field 'code' of '(incomplete) struct LinkedListSet'.
    return 1;
};
int main(){
    return (0);

Answer 1

尝试引用这样的结构

typedef struct /* my struct tag */ {
int a;
int b;
} MyStructType;

后来

MyStructType * mystruct;
mystruct->a = 34;
// etc...

Answer 2

>linkedListSet应该struct linkedListSet：

struct linkedListSet * newSet = malloc(sizeof(struct linkedListSet));

LinkedListSet应该是linkedListSet.

int addItem (struct linkedListSet * setPtr, int info)
