1、采用线性表动态分配顺序存储结构，编程实现顺序表中数据元素的逆置操作。 
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include<iostream>

using namespace std;
#define TRUE 1
#define FALSE 0
#define OK 1
#define ERROR 0
#define OVERFLOW -2
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10

typedef int Status;
typedef int ElemType;

typedef struct 
{
	ElemType *elem;
	int length;
	int listsize;
}SqList;

Status InitList_Sq(SqList &L)
{
	L.elem = (ElemType *)malloc(LIST_INIT_SIZE * sizeof(ElemType));
	if (!L.elem)
		return OVERFLOW;
	L.length = 0;
	L.listsize = LIST_INIT_SIZE;
	return OK;
}

Status ListCreate_Sq(SqList &L, int n)
{
	int i;
	srand(time(0));
	for (i = 0; i < n; i++)
	{
		L.elem[i] = rand() % 90 + 10;
		++L.length;
	}
	if (L.length == 0)
		return ERROR;
	return OK;
}

Status ListOutput_Sq(SqList L)
{
	int i;
	if (L.length == 0)
		return ERROR;
	for (i = 0; i < L.length; i++)
		printf("%d ", L.elem[i]);
	printf("\n");
	return OK;
}

Status ListConverse_Sq(SqList &L)
{
	ElemType temp;
	int i;
	if (L.length == 0)
		return ERROR;
	for (i = 0; i < L.length; i++)
	{
		temp = L.elem[i];
		L.elem[i] = L.elem[L.length - 1 - i];
		L.elem[L.length - 1 - i] = temp;
	}
	return OK;
}

void main()
{
	SqList L;
	printf("Initialize the sequential list!");
	InitList_Sq(L);
	if (L.length == 0)
		printf("The sequential list is empty!\n");
	printf("Create the sequential list!\n");
	ListCreate_Sq(L, 5);
	printf("Output all elements of the sequential list!\n");
	ListOutput_Sq(L);
	ListConverse_Sq(L);
	printf("Output all converse elements of the sequential list\n");
	ListOutput_Sq(L);

	int j;cin >> j;
	system("puase");
}

2、有一个带头结点的线性链表 L，编程实现链表中数据元素的逆置操作。要求不另设新空间。 
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include<iostream>
using namespace std;
#define TRUE 1
#define FALSE 0
#define OK 1
#define ERROR 0
#define OVERFLOW -2

typedef int Status;
typedef int ElemType;
typedef struct LNode {
	ElemType data;
	struct LNode *next;
}LNode,*LinkList;


void CreateList_L(LinkList &L, int n)
{
	LinkList p, q;
	int i;
	L = (LinkList)malloc(sizeof(LNode));
	q = L;
	srand(time(0));
	for (i = 1; i <= n; i++)
	{
		p = (LinkList)malloc(sizeof(LNode));
		p->data = rand() % 90 + 10;
		q->next = p;
		q = q->next;
	}
	q->next = NULL;
}

Status OutputList_L(LinkList L)
{
	LinkList p = L->next;
	if (p == NULL)
		return ERROR;
	while (p != NULL)
	{
		printf("%d ", p->data);
		p = p->next;
	}
	printf("\n");
	return OK;
}

Status ListConverse_L(LinkList &L)
{
	LinkList p, q;
	p = L->next;
	L->next=NULL;
	
	while (p!=NULL)
	{
		q = p;
		p = p->next;
		q->next = L->next;
		L->next=q;
	    
	}
	cout << "OK" << endl;
	return OK;
}

void main()
{
	LinkList L;
	printf("Create the linked list,");
	CreateList_L(L, 5);
	printf("Output all elements of the linked list!\n");
	OutputList_L(L);
	ListConverse_L(L);
	printf("Output all converse elements of the linked list!\n");
	OutputList_L(L);
	int j;
	cin >> j;

}

3、采用线性表动态分配顺序存储结构，编程实现顺序表中数据元素按值非递减排列。 
#include<stdio.h>
#include<stdlib.h>
#include<time.h>

#define TURE 1
#define FALSE 0
#define OK 1
#define ERROR 0
#define OVERFLOW -2
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10

typedef int Status;
typedef int ElemType;
typedef struct
{
	ElemType *elem;
	int length;
	int listsize;
}SqList;

Status InitList_Sq(SqList &L)
{
	L.elem = (ElemType *)malloc(LIST_INIT_SIZE * sizeof(ElemType));
	if (!L.elem)
		return OVERFLOW;
	L.length = 0;
	L.listsize = LIST_INIT_SIZE;
	return OK;
}

Status ListCreate_Sq(SqList &L, int n)
{
	int i;
	srand(time(0));
	for (i = 0; i < n; i++)
	{
		L.elem[i] = rand() % 90 + 10;
		++L.length;
	}
	if (L.length == 0)
		return ERROR;
	return OK;
}

Status ListOutput_Sq(SqList L)
{
	int i;
	if (L.length == 0)
		return ERROR;
	for (i = 0; i < L.length; i++)
		printf("%d ", L.elem[i]);
	printf("\n");
	return OK;
}




int Partition(SqList &L, int low, int high)
{
	int temp = L.elem[low];
	int pivotkey = L.elem[low];
	while (low < high)
	{
		while (low < high&&L.elem[high] >= pivotkey)
			--high;
	   L.elem[low] = L.elem[high];
		while (low < high&&L.elem[low] <= pivotkey)
			++low;
		L.elem[high] = L.elem[low];
	}
	L.elem[low] = temp;
	return low;
}

void QSort(SqList &L, int low, int high)
{
	if (low < high)
	{
		int pivotloc = Partition(L, low, high);
		QSort(L, low, pivotloc - 1);
		QSort(L, pivotloc + 1, high);
	}
}

void ListSort_Sq(SqList &L)
{
	QSort(L, 0, L.length-1 );
}


void main()
{
	SqList L;
	InitList_Sq(L);
	if (L.length == 0)
		printf("The sequential list is empty!\n");
	ListCreate_Sq(L, 5);
	ListOutput_Sq(L);
	ListSort_Sq(L);
	printf("Sorted:\n");
	ListOutput_Sq(L);
	system("pause");
}
