c语言有关链表问题
struct student{
int num;
char name;
char sex;
float hight;
float weight;
struct student *next;
};
void Add(struct student *head,int *n)
{
int *m=n;
int number;
struct student *p1,*p2,*p0;
if(head==0)
{
head=(struct student *)malloc(sizeof(struct student));
if(!head)
{
printf("\nError");
return;
}
else
{
printf("\nSet Success");
*m=*m+1;
}
}
p1=p2=head;
printf("\ninput plus number:\n");
scanf("%d",&number);
for(int i=0;i<*m;i++)
{
p1=p2;
p2=p1->next;
if(p1->num==number||p2->num==number)
{
printf("\nSorry!have it now");
break;
}
else if(p1->num<number&&p2->num>number)
{
p1->next=p0=(struct student *)malloc(sizeof(struct student));
scanf("%d %s %c %f %f",p1);
printf("\nRealy?(Y/N)");
char key=getchar();
if(key=='y')
{
p0->next=p2;
}
}
}
}这一段调试时没有错，就是运行不起来
