我试图在c++中测试非常基本的OO，但我遇到了一个问题。我写了以下类：
演员职业：

#pragma once
#include <string>
class Actor
{
private:
    void setName(std::string inputName);

public:
    std::string name{};
    
    Actor(std::string inputName = "Actor");

    std::string getName();

};

个字符
字符类

#pragma once
#include "Actor.h"

class Character : public Actor
{
public:
    int maxHealth{};
    int currentHealth{};

    Character(std::string inputName = "Character", int inputHealth = 100);
    int getCurrentHealth();

};

#include "Character.h"

Character::Character(std::string inputName, int inputHealth) : 
    Actor{inputName}, maxHealth{inputHealth}, currentHealth{inputHealth}
{

}

int Character::getCurrentHealth()
{
    return currentHealth;
}

的字符串
玩家等级

#pragma once
#include "Character.h"
class Player : public Character
{
public:
    Player();

};

#include "Player.h"

Player::Player():
    Character{"Player", 200}
{
    
}

#include <iostream>
#include "Player.h"

int main()
{
    Player a{};

    std::cout << "Actor name is: " + a.getName() << std::endl;
    std::cout << "Player health is: " + a.getCurrentHealth() << std::endl;
    

    return 0;
}

在本例中，a.getName()正常打印，返回字符串“Player”。但是，a.getCurrentHealth不会打印。不仅仅是数值，而是整个句子“玩家健康是：”不是打印。知道发生了什么吗
