游戏设计:

 随机输出一组N个2位数,第一步:删除玩家输入位置k处的一个数,第二步,输入一个x位置将上一步删除的数插入x处;

当所有数,从小到大排列则游戏结束,并输出总

方案一:(数组方式实现)

#include <iostream>
#include <ctime>
#include <cstdlib>
#include <iomanip>
using namespace std;

//有效输入域检测

    {
        return true;
    }
    cout << " the number must 1 to " << max <<":";
    return false;
}

//输出有效数据
void put(const int (&a)[N], int n)
{
    for (int i = 1; i <= n; i++)
    {
        cout << setw(3) << i;
    }
    cout << endl;
    for (int i = 0; i < n; i++)
    {
        cout << setw(3) << a[i];
    }
}

//删除
int del(int (&a)[N], int k)
{
    int temp = a[k - 1];
    for (int i = k; i < N; i++)
    {
        a[i - 1] = a[i];
    }
    a[N - 1] = 0;
    return temp;
}
//插入
void ins(int (&a)[N], int k, int x)
{
    for (int i = N - 1; i >= k; i--)
    {
        a[i] = a[i - 1];
    }
    a[k - 1] = x;
}

//比较
bool match(const int (&a)[N])

#include <iostream>
#include <ctime>
#include <cstdlib>
#include <iomanip>
using namespace std;
const int N = 15;
typedef struct Node *List;
struct Node
{

    }
    cout << " the number must 1 to " << max << ":";
    return false;

//创建链表
List createList(int n)

    srand(time(NULL));
    List head = NULL;
    for (int i = 0; i < n; i++)
    {
        List temp = new Node;
        temp->data = 10 + rand() % 89;
        temp->next = head;
        head = temp;
    }
    return head;
}

//输出链表
void printList(List t, int L)
{
    List temp = t;
    for (int i = 0; i < L; i++)
    {
        cout << setw(3) << temp->data;
        temp = temp->next;

//删除
List del(List &T, int k)

        while (i != k - 1)
        {
            i++;

        rTemp = temp->next;

//插入

{
    if (1 == k)
    {
        P->next = T;
        T = P;
    }
    else
    {
        int i = 1;
        List temp = T;
        while (i != k - 1)
        {
            i++;
            temp = temp->next;
        }
        P->next = temp->next;
        temp->next = P;
    }

//比较
bool match(List &T, int n)
{
    List temp = T;
    int i = 1;
    while (i != n)
    {
        i++;
        if (temp->data > temp->next->data)
        {
            return false;
        }
        else
        {
            temp = temp->next;
        }
    }
    return true;
}
//编号输出
void put(int n)
{
    for (int i = 1; i <= n; i++)
    {
        cout << setw(3) << i;
    }
    cout << endl;
}

int main()
{
    int k = 0;
    bool Gameover = false;
    put(N);
    List L1 = createList(N);
    printList(L1, N);
    while (!Gameover)
    {
        static int sub = 0;
        int key1 = 0, key2 = 0;
        cout << "  printf delate postion:";
        do
        {
            cin >> key1;
        } while (!chec(N, key1));
        put(N - 1);

        sub++;

            cout << endl
                 << "---------game over"
                 << "------tall item: " << sub * 2;
            Gameover = true;
        }
    }
    return 0;
}

 通用链表的设计:

//节点定义

typedef Node* List;

strcut Node

{

　　ElementType data;

　　List next;

}

线性表常规操作:

List MakeEmpty(); //初始化空表

ElementType FindKth(int K, List L); //根据位序k返回相应元素;

int Find(ElementType x, List L); //根据元素x,返回在表中对应的位置;

int length(List L); //返回线性表长度;

void delete(int k, List L); //删除指定位置元素;

void insert(ElementType x, int k, List L); //在指定位置插入指定元素;
