#include
typedef struct node1
{
int data;
struct node1 *next;
}node;
int count(node *head,int key)
{
node *p=head;
int n=0;
while(p)
{
if(p->data==key)
{
n++;
}
p=p->next;
return n;
}
}
还缺什么
return n;写在while循环外面
还需知道,链表带不带头结点的?供参考:
#include<stdio.h>
typedef struct node1
{
int data;
struct node1* next;
}node;
int count(node* head, int key)
{
node* p = head;
int n = 0;
while (p)
{
if (p->data == key)
{
n++;
}
p = p->next;
//return n;修改
}
return n; //移动到这
}
不缺
