Question

我在尝试编译时遇到此错误，知道发生了什么吗？我认为这与整数 maxSize 和 top 有关。当我尝试将它们更改为 "int^ maxSize" 之类的内容时，我无法使用这些整数来管理数组位置。非常感谢！

AStack.h

#pragma once

#include "Carta.h"
#define defaultSize 2048

ref class AStack
{
private:
    int maxSize;
    int top;
    array< Carta^ >^ ListArray; //puntero a arreglo

public:
    AStack();
    AStack(int size) {
        maxSize = size;
        top = 0;
        ListArray = gcnew array< Carta^ >(size);
    }

    ~AStack() { delete[] ListArray; }

    void clear() { top = 0; }

    void push(Carta^ pElement) {
        if (top == maxSize) {
            Console::WriteLine("Stack is full");
        }
        ListArray[top++] = pElement;
    }

    Carta^ pop() {
        if (top == 0) {
            Console::WriteLine("Stack empty");
        }
        return ListArray[--top]; //retorna top y despues lo decrementa
    }

    Carta^ topValue() {
        if (top == 0) {
            Console::WriteLine("Stack empty");
        }
        return ListArray[top - 1];
    }

    int length() {
        return top; //largo de pila
    }
};

Carta.h

#pragma once

using namespace System;

ref class Carta
{

private:
    String^ cara;
    String^ palo;
    String^ direccion;

public:
    Carta();
    Carta(String^ pCara, String^ pPalo) {
        cara = pCara;
        palo = pPalo;
        direccion = pCara + pPalo;
    }

    String^ print() {
        return (cara + " de " + palo);
    }

    String^ getDireccion() {
        return direccion;
    }
};

Deck.h

#include <cstdlib>
#include <ctime>
#include <iomanip>
#include "Carta.h"
#include "AStack.h"

#define ARRAY_SIZE 54

using namespace System;

ref class Deck

    int posicion;
    bool ya;

public:
    Deck() {
        ya = false;
        array<String^>^ caras = { "As","Dos","Tres","Cuatro","Cinco","Seis","Siete","Ocho","Nueve","Diez",
            "Jack","Dama","Rey" };

        array<String^>^ palos = { "Corazon","Diamante","Espada","Trebol" };

        for (int i = 0; i < ARRAY_SIZE - 2; i++) {
            deck[i] = gcnew Carta(caras[i % 13], palos[i / 13]);
        }
        deck[52] = gcnew Carta("Joker", "Negro");
        deck[53] = gcnew Carta("Joker", "Rojo");
    }

    ~Deck() {
        delete[]deck;
    }

    void mostrar() {
        for (int i = 0; i<54; i++) {
            Console::WriteLine(deck[i]->print());           
        }
    }

    void mezclar() {
        for (int primero = 0; primero < 54; primero++) {
            int segundo = (rand() + time(0)) % 54;
            Carta^ temp = deck[primero];
            deck[primero] = deck[segundo];
            deck[segundo] = temp;
        }
    }

    Carta^ topCarta() {
        return deck[0];
    }


    void cortar(int pos) {
        if (pos != 0 && pos != 53) {
            AStack^ pila;

            for (int i = pos; i < 54; i++) {
                pila->push(deck[i]);
            }

            for (int j = 0; j < pos; j++) {
                pila->push(deck[j]);
            }

            for (int k = 0; k < 54; k++) {
                deck[k] = pila->pop();
            }
        }
    }
};

Answer 1

简单的答案

不要重新发明轮子。使用 .Net 库 class System::Collections::Generic::Stack.

更复杂的答案

AStack();

这几乎可以肯定是导致错误的原因：您已经声明了一个无参数构造函数，但从未实现它。

Carta();

这里也是一样。

~AStack() { delete[] ListArray; }

这是错误的：delete[] 是分配给 new 的东西。用 gcnew 分配的东西不需要 delete[]。（你确实使用 delete，没有 []，到 Dispose objects, but array isn't an IDisposable。）
