请问我这是哪里错了？

#include<stdio.h>
#include<stdlib.h>
#define maxsize 10
typedef int elemtype;


typedef struct 
{
	elemtype date[maxsize];
	int length;
}sqlist;


void createlist(sqlist *&l,int a[],int n)
{
	int i=0,k=0;
	l=(sqlist *)malloc(sizeof(sqlist));
	while(i<n)
	{
		l->data[k]=a[i];
		k++;i++;
	}
	l->length=k;
}


void main()
{
	sqlist *h;
	int n=5;
	int a[]={1,3,1,4,2};
	createlist(h,a,n);
}

请指出错误及改正，谢谢
