print(hC); 谢谢了啊

你的格式看得人郁闷，我整理了下,思路，变量没做任何修改
[CODE]
#include <stdio.h>
#include <stdlib.h>
#include <malloc.h>
#define LEN sizeof(struct student)
struct student
{
long num;
float score;
struct student *next;
};

struct student *creat(int x)
{
int i=0;
struct student *head;
struct student *p1,*p2;
float *a,b;

a=&b; /*连接浮点库*/
p1=p2=(struct student *) malloc (LEN);
scanf("%ld,%f",&p1->num,&p1->score);
head=NULL;

while(i<x) /*这里对的，但有些麻烦*/
{
i=i+1;
if(i==1)
{
head=p1;
p2=p1;
}
else
{
p1=(struct student *)malloc(LEN);
scanf("%ld,%f",&p1->num,&p1->score);
p2->next=p1;
p2=p1;
}
}
p2->next=NULL;
return(head);

}

void print(struct student *head)
{
struct student *p;

p=head;
while(p!=NULL)
{
printf("%ld,%f\n",p->num,p->score);
p=p->next;
}
}

printf("Input the No of A line:\n");
scanf("%d",&m);
printf("Input the A records:\n");
hA=creat(m);
printf("The A results are:\n");
print(hA);
printf("Input the No of B line:\n");
scanf("%d",&n);
printf("Input the B records:\n");
hB=creat(n);
printf("The B results are:\n");
print(hB);
hC=merge(hA,hB);
printf("\nThe results are :\n");
print(hC); /*这里忘记了释放申请的内存*/
getch(); /*自己加*/
}

[/CODE]

C语言和数据结构冲突吗?~~~

我没细看..你是不是要把俩个表合并后排序..?

scanf("%ld , %f",&p1->num,&p1->score); 注意那个逗号啊.那个你注意了吗?
