程序代码：

#include <stdio.h>
#define MAXSIZE 100

typedef struct List
{
    int password[MAXSIZE];
    int last;
}SeqList;

SeqList ListInit (SeqList L)
{
    L.last = 0;
    return L;
}

SeqList ListInsert (SeqList L)
{
    int i, n;

    printf ("n=");
    scanf ("%d", &n);
    L.last = n;
    for (i=0; i<n; i++)
    {
        scanf ("%d", &L.password[i]);
    }
    return L;
}

void mian ()
{

    SeqList L;
    int m;

    L = ListInit (L);
    ListInsert (L);

    for (m=0; m<L.last; m++)
    {
        printf ("%d ", L.password[m]);
    }
   
}
