关于链表的问题
就是第一部插入元素的时候就出问题了,只能插两个元素,我想要插三个。然后他不让输了以后也不会进行接下来的操作,就直接跳出这个程序了,这要怎么解决啊#include <stdio.h>
#include <stdlib.h>
#define MAXSIZE 10000
#define N 3
typedef struct
{
char No; //书的编号
char name; //书的名字
float price; //书的价格
} Book;
typedef struct
{
Book *elem;
int lenght;
} SqList;
void InitList(SqList &L);
void GetElem(SqList L, int i, Book &e);
int LocateElem(SqList L, Book e);
void ListInsert(SqList &L, int i, Book e);
void ListDelete(SqList &L, int i);
int main()
{
SqList p1;

Book e1, e2;
int p;
