C++ 具有相同构造函数的许多类

我有很多类，它们的参数非常相似。有没有办法写得更简洁/整洁？编写一个包含成员变量的基类会有所帮助，但我仍然需要为每个类编写构造函数

class CommandDrawLiver {
    protected:
        int age;
        Species species;
        double r, g, b;
    public:
        CommandDrawLiver( int _age, Species _species, double _r, double _g, double _b )
          : age(_age), species(_species), r(_r), g(_g), b(_b)
          {};
};
class CommandDrawBrain {
    protected:
        int age;
        Species species;
        double r, g, b;
    public:
        CommandDrawBrain( int _age, Species _species, double _r, double _g, double _b )
          : age(_age), species(_species), r(_r), g(_g), b(_b)
          {};
};
class CommandDrawHeart {
    protected:
        int age;
        Species species;
        double r, g, b;
    public:
        CommandDrawHeart( int _age, Species _species, double _r, double _g, double _b )
          : age(_age), species(_species), r(_r), g(_g), b(_b)
          {};
};

假设您使用的是支持C++11的编译器，这就是它的用途。。。 检查并使用它

下面是如何应用它

class Species{};

class CommandDraw {
    protected:
        int age;
        Species species;
        double r, g, b;

    public:
        CommandDraw( int _age, Species _species, double _r, double _g, double _b )
          : age(_age), species(_species), r(_r), g(_g), b(_b)
          {};
};

class CommandDrawLiver : public CommandDraw {
    public:
        using CommandDraw::CommandDraw;
};
class CommandDrawBrain : public CommandDraw {
    public:
        using CommandDraw::CommandDraw;
};
class CommandDrawHeart : public CommandDraw {
    public:
        using CommandDraw::CommandDraw;
};

int main() {
    CommandDrawLiver cd(34, Species(), 12, 45, 67);
    }

某种工厂功能模板<代码>模板T makeCommandDraw（int，Species&，double，double，double）{/…}。欢迎使用。我刚刚编辑了答案以显示用法，如果这解决了您的问题，您可以将其标记为已回答：-）
