请求大神们看看这个程序哪里出错了程序：创建一个链表，输入信息，打印。#include<stdio.h>#include<malloc.h>#include<string.h>struct AA{ int num; char sex; char name[20]; struct AA *next;};struct AA *creatlist(int count){ struct AA *head=NULL,*tmp,*p; char sex1,*name1=NULL; int n=0,num1; for(n=0;n<count;n++) { tmp=(struct AA *)malloc(sizeof(struct AA)); scanf("%d",&num1); tmp->num=num1; scanf("%c",sex1); tmp->sex=sex1; gets(name1); strcpy(tmp->name,name1); tmp->next=NULL; if(head==NULL) { head=p=tmp; } else { p->next=tmp; p=p->next; } } p=head; while(p!=NULL) { printf("%d%c%s",p->num,p->sex,p->name); p=p->next; } return 0;}void main(){ int count; scanf("%d",&count); creatlist(count);}
