请帮我看看这段程序里的typedef哪错了，谢谢
#include <stdio.h>
#include <stdlib.h>
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10
struct list
{ int *elem;
int length;
int listsize;
};
typedef struct list *sqlist;
int InitList(sqlist L)
{ L-> elem=(int *)malloc(LIST_INIT_SIZE*sizeof(int));
if(!L-> elem)exit(0);
L-> length=0;
L-> listsize=LIST_INIT_SIZE;
return 1;
}
int InputToList(sqlist L,int len)
{ int i;
for(i=0;i <len;i++)
scanf( "%d ",L-> elem[i]);
L-> length=len;
return 1;
}
void ShowList(sqlist L)
{ int i;
printf( "the elements of the list are:\n ");
for(i=0;i <L-> length;i++)
printf( "%3d ",L-> elem[i]);
printf( "\n ");
}
main()
{ int La_len,Lb_len;
printf( "please input the length of La: ");
scanf( "%d ",&La_len);
printf( "\n ");
printf( "please input the length of Lb: ");
scanf( "%d ",&Lb_len);
printf( "\n ");
sqlist La,Lb;
InitList(La);
InitList(Lb);
printf( "input elements to La\n ");
InputToList(La,La_len);
printf( "\ninput elements to Lb\n ");
InputToList(Lb,Lb_len);
ShowList(La);
ShowList(Lb);
getchar();
}
想写一段线性表的初始化和显式的代码，可是用VC6.0编译的时候总出现以下错误：

用Tc2.0编译也出现相似的错误，c语言用的太少，实在检查不出哪里出错，可笑之处还望见谅。请各位不吝赐教，给予宝贵提示，感激不尽。

[解决办法]
sqlist La,Lb;、、貌似未初始化的指针
