线性表有两种存储方法:顺序存储和链式存储

它的基本操作是插入,删除和查找。

顺序表中的插入:

在第i个位置上插入一个值为x的新元素
插入前:(a1,a2…a i-1,ai,ai+1,…an)
插入后:(a1,a2…ai-1,x,ai,ai+1,…,an) (1<=i<=n+1)

int Insert_SeqList(SeqList *L,int i,datatype x)

{
int j;
if(L->last==MAXSIZE-1)
{
printf(“表满”);
return(-1);
}
if(i<1||i>L->last+2)
{
printf("位置错误”);
return(0);
}
for(j=L->last;j>i-1;j–)
L->data[j+1]=L->data[j];
L->data[i-1]=x;
L->last++;
return 0;
}
(L->last 指表中最后一个元素)

单链表(1)在表头插入LinkList   Creat_LinkList1(){        LinkList  L=NULL;         LNode *s;         int   x;         scanf("%d",&x);         while(x!=flag)         {             s=(LNode*)malloc(sizeof(LNode));              s->data=x;              s->next=L;                  L=s;                  scanf("%d",&x);         }         return L; }
