初学者 程序中的错误 高手帮忙看下

#include "stdio.h"
#include "stdlib.h"
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10
#define OK 1
#define ERROR 0
#define OVERFLOW -2
typedef int Status;
typedef int Elemtype;
typedef struct
{
        Elemtype *elem;
        int length;
        int listsize;

}sqlist;

Status Inslist(sqlist *L,int i)
{int m,*p,*q;
if(i>L.length||i<1)
return 0;
printf("请输入想要插入的元素:");
scanf("%d\n ",&m);
q=&(L.elem[i-1]);
for(p=&(L.elem[L.length-1]);p>=q;--p)
*(p+1)=*p;
*q=m;
++L.length;
printf("新表的元:");
for(m=0;m<L.length;++m)
printf("%d  ",L.elem[m]);
printf("表长为:%d,容量为:%d",L.length,L.listsize);
return 1;
}
void main()
{int i,m,n;
sqlist *L;
L.elem=(Elemtype*)malloc(LIST_INIT_SIZE*sizeof(Elemtype));
if(!L.elem)exit(OVERFLOW);
L.length=0;
L.listsize=LIST_INIT_SIZE;
printf("请输入元素个数:");
scanf("%d",&m);
if(m>L.listsize)
return 0;
L.length=m;
printf("请输入元素:\n");
for(i=1;i<=m;++i)
{scanf("%d ",&L.elem);
++L.elem;
}
printf("请输入要插入的元素位置:");
scanf("%d",&m);
Inslist(L,m);
}
我初步编的就有许多同样的错误

执行 cl.exe 时出错.

#include "stdio.h"
#include "stdlib.h"
不是“”应该是<>

感觉LZ的代码好像就是伪代码吧。

数据结构书上的？
