皆さん、Java のコードを C++ に変換するのに助けが必要です。Java から C++ へのプライベート型としてクラスをインスタンス化するにはどうすればよいですか? これが私が言いたいことです、私はいくつかのコード行です：

最初の問題: 解決しました。

2 番目の問題: この Java コードは私が変換したかったものです。コードのどこが間違っていると思いますか?

Java の元のコード:

public class ClueReasoner 
{
private int numPlayers;
private int playerNum;
private int numCards;
private SATSolver solver;    
private String caseFile = "cf";
private String[] players = {"sc", "mu", "wh", "gr", "pe", "pl"};
private String[] suspects = {"mu", "pl", "gr", "pe", "sc", "wh"};
private String[] weapons = {"kn", "ca", "re", "ro", "pi", "wr"};
private String[] rooms = {"ha", "lo", "di", "ki", "ba", "co", "bi", "li", "st"};
private String[] cards;

public ClueReasoner()
{
    numPlayers = players.length;

    // Initialize card info
    cards = new String[suspects.length + weapons.length + rooms.length];
    int i = 0;
    for (String card : suspects)
        cards[i++] = card;
    for (String card : weapons)
        cards[i++] = card;
    for (String card : rooms)
        cards[i++] = card;
    numCards = i;

    // Initialize solver
    solver = new SATSolver();
    addInitialClauses();
}

private int getPlayerNum(String player) 
{
    if (player.equals(caseFile))
        return numPlayers;
    for (int i = 0; i < numPlayers; i++)
        if (player.equals(players[i]))
            return i;
    System.out.println("Illegal player: " + player);
    return -1;
}

private int getCardNum(String card)
{
    for (int i = 0; i < numCards; i++)
        if (card.equals(cards[i]))
            return i;
    System.out.println("Illegal card: " + card);
    return -1;
}

private int getPairNum(String player, String card) 
{
    return getPairNum(getPlayerNum(player), getCardNum(card));
}

private int getPairNum(int playerNum, int cardNum)
{
    return playerNum * numCards + cardNum + 1;
}

私のコード:

#include <iostream>
#include <cstdlib>
#include <string>

using namespace std;

void Scene_Reasoner() {
int numPlayer;
int playerNum;
int cardNum;
 string filecase = "Case: ";
 string players [] = {"sc", "mu", "wh", "gr", "pe", "pl"};
 string suspects [] = {"mu", "pl", "gr", "pe", "sc", "wh"};
string weapons []  = {"kn", "ca", "re", "ro", "pi", "wr"};
 string rooms[] = {"ha", "lo", "di", "ki", "ba", "co", "bi", "li", "st"};
 string cards [0];
};

void Scene_Reason_Base () {
    numPlayer = players.length;

    // Initialize card info
    cards = new String[suspects.length + weapons.length + rooms.length];
    int i = 0;
    for (String card : suspects)
        cards[i++] = card;
    for (String card : weapons)
        cards[i++] = card;
    for (String card : rooms)
        cards[i++] = card;
    cardNum = i;
    };

    private int getCardNum (string card) {
            for (int i = 0; i < numCards; i++)
        if (card.equals(cards[i]))
            return i;
    cout << "Illegal card: " + card <<endl;
    return -1;
    };

     private int getPairNum(String player, String card)
   {
    return getPairNum(getPlayerNum(player), getCardNum(card));
};

  private int getPairNum(int playerNum, int cardNum)
  {
    return playerNum * numCards + cardNum + 1;
};

int main () {
return 0;
}

C++ で SATSolver を実装していますか? もしそうなら、サンプルコードがあります：

class Foo
{
private:
    int numPlayers;
    int playerNum;
    int numCards;
    SATSolver solver;

    // etc
};

別のクラス内で のプライベート インスタンスを宣言したい場合はSATSOlver、次のように実行できます。

ファイル SATSolver.h

class SATSolver {
// methods, members, etc....
};

ファイル Foo.h

#include "SatSolver.h" // get the SATSolver declaration

class Foo
{

 private: // everything that follows is private access

  SATSolver solver;

 public: // from here on, everything is public
  // more code

 private: // and now, all that follows is private again
  // stuff
}

C++ では、アクセス指定子はクラスまたは構造体でのみ許可されることに注意してください。関数内、またはクラスまたは構造体の外部で型または値を修飾することはできません。

C++ では、 aclassにはデフォルトでプライベート アクセス (および継承がありますが、それはこの質問の範囲外です) があることに注意してください。

class Bar {
  SATSolver solver; // private
}

あなたのコードは私たちのコンバーターを壊しました - 私たちはそれを修正し、コンパイル可能な C++ の同等物は次のとおりです:

#include <string>

    int numPlayers;
    int playerNum;
    int numCards;

    std::string caseFile;
    std::string players[6];
    std::string suspects[6];
    std::string weapons[6];
    std::string rooms[9];
//ORIGINAL LINE: private String[] cards;
//JAVA TO C++ CONVERTER WARNING: Since the array size is not known in this declaration, Java to C++ Converter has converted this array to a pointer.  You will need to call 'delete[]' where appropriate:
    std::string *cards;

public:
    ClueReasoner()
