怎么回事？

int main(void)
 {
     PNODE create_list(void);
     void traverse_list(PNODE );
     PNODE pHead=NULL;//等价于struct Node *pHead=NULL
    pHead=create_list();
     traverse_list(pHead);

return 0;
 }

不对啊，这个程序在linux T中运行正确！

PNODE create_list(void)
 {
     int len,i;
     int val;
     //在这定义

     PNODE pHead1=(PNODE)malloc(sizeof(NODE));

     if (NULL==pHead1)
         {printf("fenpeishibai ,chengxvzhongzhi!");
             exit(-1);
         }

    PNODE pTail=pHead1;
     pTail->pNext=NULL;

     printf("qingshurujiedianshu :len =");
     scanf("%d",&len);

     for (i=0;i<len;i++)
         {
            //移到这里
             printf("qingshuru di %d jiedian shujv :",i+1);
             scanf("%d",&val);

             PNODE pNew=(PNODE)malloc(sizeof(NODE));
                 if (NULL==pNew)
                     {
                         printf("fenpeishibai ,chengxvzhongzhi!");
                         exit(-1);
                     }

             pNew->DATA=val;

             pTail->pNext=pNew;
             pNew->pNext=NULL;
             pTail=pNew;


 }
vc貌似在一个作用域里定义全部要放到前面，具体没深究过。

哦哦，明白了，谢谢！

楼主打基础的阶段，最好了解清楚了。提示一下，搜索关键字“C语言变量定义位置”。

嗯嗯，谢谢，敢问，我想深入学c需要做些什么？
