简单链表问题，求教

[mars131]

这是一个创建链表的程序，可是不知道为什么运行的时候会出错，错误在for 循环的
L->next = NULL语句上，兄弟们帮我看看，vs和dev-c++上都有错，编译是可以通过的


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


struct LNode
{
int number;
struct LNode *next;
}*Linklist;

void CreatList(struct LNode *L,int n)
{

int i;
for(i= n;i>0;--i)
{
struct LNode *p;
p = (struct LNode *)malloc(sizeof(struct LNode));
printf("please enter the int:");
scanf("%d",&p->number);
printf("%d",(*p).number);
// p->next = L->next;
L->next = NULL;
//printf("/n the number %d struct is succesfull", i);
}
}


int main(int argc, char *argv[])
{
struct LNode *L;
L = (struct LNode *)malloc(sizeof(struct LNode));
L->next = NULL;
CreatList(Linklist,3);
system("PAUSE");
return 0;
}

呵呵，真是谢谢你们，星期六还这么快的帮助我，回答的那么详细：），感动
缘分啊~~~~~~~~~~~

[languagec]

void CreatList(struct LNode *L,int n)
{

int i;
for(i= n;i>0;--i)
{
struct LNode *p;
p = (struct LNode *)malloc(sizeof(struct LNode));
printf("please enter the int:");
scanf("%d",&p->number);
printf("%d",(*p).number);

p->next = L->next;
L->next = p;

//printf("/n the number %d struct is succesfull", i);
}
}

[languagec]

没插好

[llf_hust]

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


struct LNode
{
int number;
struct LNode *next;
}*Linklist;

void CreatList(struct LNode **L,int n)
{

int i;
for(i= n;i>0;--i)
{
struct LNode *p;
p = (struct LNode *)malloc(sizeof(struct LNode));
printf("please enter the int:");
scanf("%d",&p->number);
printf("%d",(*p).number);
p->next = (*L)->next;
*L = p;

}
}


int main()
{
struct LNode *L;
int i;
L = (struct LNode *)malloc(sizeof(struct LNode));
L->next = NULL;
CreatList(&L,3);


system("PAUSE");
return 0;
}

帮你改了：

struct LNode
{
int number;
struct LNode *next;
}*Linklist;

void CreatList(struct LNode *L,int n)
{

int i;
for(i= n;i>0;--i)
{
struct LNode *p;
p = (struct LNode *)malloc(sizeof(struct LNode));
printf("please enter the int:");
scanf("%d",&p->number);
printf("%d",(*p).number);
// p->next = L->next;
L->next = p; ///////////////////////////
L = L->next; ////////////////////////////
//printf("/n the number %d struct is succesfull", i);
}
}


int main(int argc, char *argv[])
{
struct LNode *L;
L = (struct LNode *)malloc(sizeof(struct LNode));
L->next = NULL;
CreatList(L,3); /////////////////////////
system("PAUSE");
return 0;
}

你原来的程序里：
int main(int argc, char *argv[])
{
struct LNode *L;
L = (struct LNode *)malloc(sizeof(struct LNode));
L->next = NULL;
CreatList(Linklist,3); //Linklist只是一个指针，没有分配内存。
system("PAUSE");
return 0;
}

for(i= n;i>0;--i)
{
struct LNode *p;
p = (struct LNode *)malloc(sizeof(struct LNode));
printf("please enter the int:");
scanf("%d",&p->number);
printf("%d",(*p).number);
L->next=p;
p->next = NULL;
L=p;
printf("/n the number %d struct is succesfull", i);
}
