求助编译错误：illegal use of this type as an expression

[ZhengZhiRen]

实在不知道哪错了，急啊。
帮忙看看，谢了！

#include <stdio.h>
#include <stdlib.h>

typedef struct node
{
int i;
struct node *next;
}node;

void fun(node *p,int i)
{
int count=1;
node *q;
q=p->next;
while(q->next!=q)
{
if(count%i==0)
{
p->next=q->next;
printf("%d",q->i);
free(q);
}
else
p=p->next;
q=p->next;
count++;
}
printf("%d",q);
}

void main()
{
int i;
int num;
printf("please input number:\n");
scanf("%d",&num);

这个代码看得清楚点

#include <stdio.h>
#include <stdlib.h>

typedef struct node
{
	int i;
	struct node *next;
}node;

void fun(node *p,int i)
{
	int count=1;
	node *q;
	q=p->next;
	while(q->next!=q)
	{
		if(count%i==0)
		{
			p->next=q->next;
			printf("%d",q->i);
			free(q);
		}
		else
			p=p->next;
		q=p->next;
		count++;
	}
	printf("%d",q);
}

void main()
{
	int i;
	int num;
	printf("please input number:\n");
	scanf("%d",&num);
	node *circle;
	node *p;
	node *q;
	/*初始化循环链表*/
	circle=(node*)malloc(sizeof(node));
	circle->i=1;
	circle->next=circle;
	p=circle;
	for(i=2;i<=100;i++)
	{
		q=(node*)malloc(sizeof(node));
		q->i=i;
		q->next=p->next;
		p->next=q;
		p=p->next;
	}
	fun(circle,num);
}

[帅得不敢出门]

你用的什么编译器
除了main返回int外 gcc编译其他代码没有问题啊.

[lzr4304061988012]

LZ,vs2008编译通过，且正常运行

[帅得不敢出门]

vc6.0也编译通过
代码没啥问题的
你rebuild一下
或者新建个工程试试
还有工程类型没选错吧

[星羽]

帮你改好了

#include <stdio.h>
#include <stdlib.h>

/* 这里定义要改成这样，你之前重名了*/
typedef struct _node
{
    int i;
    struct _node *next;
}node;

void fun(node *p,int i)
{
    int count=1;
    node *q;
    q=p->next;
    while(q->next!=q)
    {
        if(count%i==0)
        {
            p->next=q->next;
            printf("%d",q->i);
            free(q);
        }
        else
            p=p->next;
        q=p->next;
        count++;
    }
    printf("%d",q);
}

void main()
{
    int i;
    int num;
    node *circle;
    node *p;
    node *q;               /*在c语言里要把所有定义放最前面*/

    printf("please input number:\n");
    scanf("%d",&num);

    /*初始化循环链表*/
    circle=(node*)malloc(sizeof(node));
    circle->i=1;
    circle->next=circle;
    p=circle;
    for(i=2;i <=100;i++)
    {
        q=(node*)malloc(sizeof(node));
        q->i=i;
        q->next=p->next;
        p->next=q;
        p=p->next;
    }
    fun(circle,num);
}

[Quote=引用 5 楼 Chiyer 的回复:]
帮你改好了

    int i;
    int num;
    node *circle;
    node *p;
    node *q;               /*在c语言里要把所有定义放最前面*/

    printf("please input number:\n");
    scanf("%d",&num);

谢谢你！
node *circle;
node *p;
node *q;
是我后来加上的，忘了放在scanf后面了！解决了

[ZhengZhiRen]

另外问下
typedef struct _node
{
int i;
struct _node *next;
}node;
这里重名会出问题吗？我看一些书上就是重名的啊。

[galilio]

推荐使用
typedef struct node{
****
}node
