C ++不将名称命名为类型 [英] C++ Does not name to a type

问题描述

这可能是一个容易的问题，但我不知道为什么编译器它给我这个错误。我有两个类。代理和环境。当我尝试添加一个类型的代理在我的环境类中的对象我得到代理不命名为类型错误。我在我的Environment.h类中包括Agent.h

This might be an easy question, but I cannot figure out why the compiler it's giving me this error. I have two classes. Agent and Environment. WHen I try to add an object of type Agent in my Environment class I get Agent does not name to a type error. I am including Agent.h in my Environment.h class

#ifndef AGENT_H_INCLUDED
#define AGENT_H_INCLUDED

#include <vector>
#include <iostream>
#include "Environment.h"

using namespace std;

class Agent{
    public:
        Agent(bool s);
        vector<int> getPercept();
        void setPercept(vector<int> p);
        void goForward();
        void turnRight();
        void turnLeft();
        void clean();
        void paint();
        void refuel();
        bool needsRefuel();
        void turnOn();
        void turnOff();
        bool isActive();
        void move();
        int getCurX();
        int getCurY();
        char getCurDir();
        void setCurrentPosition(int x, int y, char d);

        bool isOn;
        int curX;

推荐答案

您的代理.h包括environment.h。 agent.h文件按照从上到下的顺序解析，因此当解析environment.h时，编译器不知道代理是什么。似乎没有理由在agent.h中引入environment.h。

Your agent.h includes environment.h. The agent.h file is parsed in order from top to bottom, so when environment.h is parsed, the compiler doesn't know what an Agent is. There appears to be no reason to incude environment.h in agent.h.
