显示操作成功

但文件数据还在,程序重新启动后,删除的链表又恢复了,怎么办?
各位帮帮我吧!
int deleteBookList(struct node* head, int IBSN)
{
struct node *p=NULL, *pre=NULL;int status = 0;if(head!=NULL){pre=head;p=head->next;while(p!=NULL){if(p->book.IBSN==IBSN){pre->next = p->next;free(p);status = 1;break;}pre = p;p = p->next;}}return status;}
void deleteBook(struct node *head)
{
printf("请输入要删除的图书编号:");char a[1024];int IBSN=0;if (fgets(a, 1024, stdin)!= NULL &&sscanf(a, "%d", &IBSN)!=EOF){if (deleteBookList(head, IBSN)){printf("该编号%d对应的图书信息删除成功!\n", IBSN);}else
{
printf("该编号对应的图书信息不存在!\n");
}
}
else
{
printf("输入有误,请重新输入!\n");
}
}
解决了,我忘了写进文件了,嘿嘿嘿
