上个月关门了。
我正在处理一个将java转换为c的赋值,我已经完成了所有的工作,但是在c版本中,重写函数不能正常工作。。。
以下是java版本:

abstract class ForceBeing {
    private int power_level;
    private String name;
    private boolean evil;

    protected ForceBeing(int level) {
        power_level = level;
    }

    protected void setPowerLevel(int level) {
      power_level = level;
    }

    public int getPowerLevel() {
      return power_level;
    }

    protected void setName(String characterName) {
      name = characterName;
    }

    public String getName() {
      return name;
    }

    public void setEvil() {
      evil = true;
    }

    public void setGood() {
      evil = false;
    }

  }

  class Jedi extends ForceBeing {

    public Jedi(String jediName, int level) {
        super(level);
        setName(jediName);
        setGood();
    }

    public int getPowerLevel() {
      return super.getPowerLevel() + 1;
    }
  }

  class Sith extends ForceBeing {
    public Sith(String sithName, int level) {
        super(level);
        setName(sithName);
        setEvil();
    }

    public int getPowerLevel() {
      return super.getPowerLevel() - 1;
    }

    public String getName() {
      return "Sith Lord: " + super.getName();
    }
  }

  public class StarWars {

      public static String getWinner(ForceBeing player1, ForceBeing player2) {
          return player1.getPowerLevel() > player2.getPowerLevel() ? player1.getName() : player2.getName();
      }

      public static void printWinner(String winner) {
          System.out.println("The winner is: " + winner);
      }

      public static void main(String[] args) {
          Sith darthVader = new Sith("Darth Vader",100);
          Jedi lukeSkyWalker = new Jedi("Luke Skywalker",99);
          printWinner(getWinner(darthVader, lukeSkyWalker));
      }
  }

输出:

The winner is: Luke Skywalker

就像它应该的那样。
这是我转换的c++:


# include <iostream>

# include <string>

using namespace std;

class ForceBeing
{
private:
  int power_level;
  string name;
  bool evil;

protected:
  ForceBeing(int level)
  {
    power_level = level;
  }

  void setPowerLevel(int level)
  {
    power_level = level;
  }

  void setName(string characterName)
  {
    name = characterName;
  }

public:
  int getPowerLevel()
  {
    return power_level;
  }

  string getName()
  {
    return name;
  }

  void setEvil()
  {
    evil = true;
  }

  void setGood()
  {
    evil = false;
  }
};

class Jedi : public ForceBeing
{
public:
  Jedi(string jediName, int level) : ForceBeing(level)
  {
    setName(jediName);
    setGood();
  }

  int getPowerLevel()
  {
    return ForceBeing::getPowerLevel() + 1;
  }
};

class Sith : public ForceBeing
{
public:
  Sith(string sithName, int level) : ForceBeing(level)
  {
    setName(sithName);
    setEvil();
  }

  int getPowerLevel()
  {
    return ForceBeing::getPowerLevel() - 1;
  }

  string getName()
  {
    return "Sith Lord: " + ForceBeing::getName();
  }
};

static string getWinner(ForceBeing player1, ForceBeing player2)
{
  // return player1.getPowerLevel() > player2.getPowerLevel() ? player1.getName() : player2.getName();
  cout << "Player 1 Name: " << player1.getName() << " PowerLevel: " << player1.getPowerLevel() << endl;
  cout << "Player 2 Name: " << player2.getName() << " PowerLevel: " << player2.getPowerLevel() << endl;
  if (player1.getPowerLevel() > player2.getPowerLevel())
  {
    return player1.getName();
  }
  else
  {
    return player2.getName();
  }
};

static void printWinner(string winner)
{
  cout << "The winner is: " << winner << endl;
};

int main()
{
  Sith darthVader("Darth Vader", 100);
  Jedi lukeSkyWalker("Luke Skywalker", 99);
  printWinner(getWinner(lukeSkyWalker, darthVader));
  return 0;
}

输出:

Player 1 Name: Luke Skywalker PowerLevel: 99
Player 2 Name: Darth Vader PowerLevel: 100
The winner is: Darth Vader

当我期望它输出:

Player 1 Name: Luke Skywalker PowerLevel: 100
Player 2 Name: Sith Lord: Darth Vader PowerLevel: 99
The winner is: Luke Skywalker

我盯着这个看了一个小时都不知道。。。有人有更好的线索吗?提前感谢您的帮助!
