想实现数据结构中顺序有序表的合并（c实现），大佬们能找找逻辑错误不

#include
#define MAXSIZE 100 
typedef struct SeqList//顺序表的存储结构
{
	int elem[MAXSIZE];
	int length;
 }SqList;
 
void MergeList_Sq(SqList LA,SqList LB,SqList &LC)
{
	int *p1,*p2,*q;
	LC.length=LA.length+LB.length;
	p1=LA.elem;
	p2=LB.elem;
	q=LC.elem;
	while(p1&&p2)
	{
		if(*p1<=*p2)
		{
			*q=*p1;
			p1++;
		}
		else
		{
			*q=*p2;
			p2++;
		}
		q++;
		
	}
	while(p1)
	{
		*q=*p1;
		p1++;
		q++;
	}
	while(p2)
	{
		*q=*p2;
		p2++;
		q++;
	}
	
}

int Input(SqList &L,int n)
{
	if(n<1||n>MAXSIZE)
		return 0; 
	int i;
	L.length=0;
	for(i=0;i
