通过单个链表和两个类别查找最小和最大数字

问题描述

我通过单个链接列表从用户那里获得了多个数字，我的程序的任务是按两个类在链接列表中找到最小和最大的数字，并将其打印在屏幕上。但是过了一段时间，我的程序关闭了，我什么也没看到。出了什么问题？

#include<iostream>
using namespace std;

struct Node
{
    double Number;
    struct Node *Point;

} *End = nullptr;
typedef struct Node node;

namespace Min_Max
{
    class Min
    {
        node *Result = End;

        public: Min()
        {
            if(Result == nullptr)
            {
                cout << "You didn\'t enter anything!\a";
                system("pause");

                exit(EXIT_FAILURE);
            }

            node *Counter = Result->Point;

            while(Counter != nullptr)
            {
                if(Counter->Number < Result->Number)
                    Result = Counter;

                Result = Result->Point;
            }
        }

        node* Show()
        {
            return Result;
        }
};

class Max
{
    private:
        node *Result = End;

    public: 
        Max()
        {
            if(Result == nullptr)
            {
                cout << "You didn\'t enter anything!\a";
                system("pause");

                exit(EXIT_FAILURE);
            }

            node *Counter = Result->Point;

            while(Counter != nullptr)
            {
                if(Counter->Number > Result->Number)
                    Result = Counter;

                Result = Result->Point;
            }
        }

        node* Show()
        {
            return Result;
        }
    };
};

int main()
{
    node *linker = nullptr;
    register short int Counter = 1;

    while(1)
    {
        linker = new node;
        if(linker == nullptr)
        {
            cout << "An error occurred during allocating memory." << endl << endl;
            system("pause");

            return 0;
        }

        cout << "Number " << Counter << ": Enter your number: ";
        cin >> linker->Number;
        system("cls");

        if(linker->Number == 0)
        {
            delete linker;
            break;
        }

        linker->Point = End;
        End = linker;

        Counter++;
    }

    Min_Max::Min Min;
    Min_Max::Max Max;

    cout << "The smallest number is " << (Min.Show())->Number << endl;
    cout << "The largest number is " << (Max.Show())->Number << endl;

    return 0;
}

我的C ++编译器是GCC-C ++ 11，操作系统是Windows 10。
