C - .h和.c文件中的冲突类型

Question

我收到了一个错误error: conflicting types for 'initList'，其中有一些代码是通过.c文件和.h文件写入的。下面是.c文件中的代码：

#include "lists.h" 

void initList(LIST* list) { 
    list->head.coef = 0; 
    list->head.exp = 0; 
} 

下面是在.h文件中相应的代码：

#ifndef LISTS_H__ 
#define LISTS_H__ 

#include <stdio.h> 
#include <string.h> 

typedef struct node { 
    int coef; 
    int exp; 
    struct node* next; 
} NODE; 

typedef struct list { 
    NODE head; 
} LIST; 

void initList(LIST*); 

#endif 

我真不明白我在做什么错在这里...我已经检查了其他类似的问题，但是他们的答案中没有一个提出了解决方案，并且/或者我已经有了修复程序。

首先，变量的单词列表不是一个好的选择。继续。

从我所看到的情况看来，您正在制作一个自引用结构，尽管头元素是一个单独的结构，但与结点具有相同的结构。

像一些评论，我也没有得到任何错误与您发布的代码，所以为了帮助你，这里是一些代码，使用你必须创建一个列表，然后添加值并链接列表和节点在一起。我还使用 - >运算符更改了最后一个节点。

我希望这可以帮助你。

在h文件中。

/* 
* 35352860_list.h 
*/ 

#ifndef _35352860_LIST_H__ 
#define _35352860_LIST_H__ 

#include <stdio.h> 
#include <string.h> 

typedef struct node 
    { 
     int coef; 
     int exp; 
     struct node* next; 
    } NODE; 

typedef struct list 
    { 
    NODE head; 
    } LIST; 

void initList(LIST*); 

#endif /* _35352860_LIST_H__ */ 

和c文件。

/* 
* 35352860_main.c 
*/ 

#include "35352860_list.h" 

void initList(LIST* list) 
    {

    list->head.exp = 0x0000; 
    list->head.next = NULL; 
    }

    (

    unsigned char *arg[]
