你好，我想做一个有点像口袋妖怪的游戏，但是我被打印统计数据困住了。 我试图用它输出一个水平，显示动物达到了什么水平。

对我没有得到预期结果有什么帮助吗？

我的代码:

VisualAnimal.h（尚未使用）:

#include <string>

#ifndef VISUALANIMAL_H
    #define VISUALANIMAL_H

using namespace std;
using namespace Animals;

/*** Visual based on original class
@author Adam Petla
***/
class VisualAnimal : Animal {
public:
    string imageFileURL;
    int size;
    VisualAnimal() {
        this->imageFileURL = "";
        this->size = 0;
    }
};
#endif

动物。H:

#include <string>
#include <stdio.h>
#include <iostream>

#ifndef ANIMAL_H
    #define ANIMAL_H

using namespace std;
namespace Animals {
    class Animal {
    public:
        string name;
        int minlevel;
        int level;
        int maxlevel;
        int baseattack;
        int baseattackraise;
        int attack;
        int basedefense;
        int basedefenseraise;
        int defense;
        int basespeed;
        int basesppedraise;
        int speed;
        int basespecial;
        int basespecialraise;
        int special;
        char type;
        Animal() {
            name = "DOG";
            minlevel = 0;
            level = 1;
            maxlevel = 100;
            baseattack = 1;
            baseattackraise = 1;
            basedefense = 1;
            basedefenseraise = 1;
            basespecial = 1;
            basespecialraise = 1;
            basespeed = 1;
            basesppedraise = 1;
        };
    private:
        void  printstats() {
            //cout << "Attack : " << this->
        };
        void raiseattack() {
            this->attack += this->baseattackraise;
        }
        void raisedefense() {
            this->defense += this->basedefenseraise ;
        }
        void raisespeed() {
            this->speed += this->basesppedraise;
        }
        void raisespecial() {
            this->special += this->basespecialraise;
        }
        void raisestats() {
            raiseattack();
            raisedefense();
            raisespeed();
            raisespecial();
        }
        void updatestats(char  type) {
            switch (type) {
            case 'l':
                raisestats();
            }
        }
       public :
            void raiselevel() {
                   this->level++ ;
                   this->type = 'l';
                   updatestats(this->type);
                   string output = "Level Up!Your " +  string(this->name) + string("has reached level");
                    cout << output;
                    cout << this->level + ".Its stats are now";
                    printstats();
            };
        };
    }
    #endif

animal.cpp:

// Animals.cpp : This file contains the 'main' function. Program execution begins and ends there.
//

#include <iostream>
#include "animal.h"
#include "visualanimal.h"

using namespace std;
int main()

{

    using namespace`` Animals;
    Animal test;
    test.raiselevel();
    cout << "Hello World!\n";
    return -1;
}

我的预期结果:狗达到2级。 我的实际结果狗达到水平，任何人知道一个答案，它没有显示任何水平的输出，任何人知道为什么？
