C++错误：CA 时无效使用'AppleFarmer::AppleFarmer'

我收到错误"错误：AppleFarmer::AppleFarmer使用无效。我不知道为什么我会收到此错误，因为我没有尝试将任何输入传递到我的构造函数中。我的 .h 文件可能有问题吗？我做错了什么才能得到这个错误？我有三个不同的文件，当我正在为.cpp文件执行#include时，我也可能遇到将代码链接在一起的问题。我不确定我的代码是否除了此错误之外还能工作，但我被困在此错误上。

苹果农主.cpp

#include<iostream>
#include "appleFarmer.cpp"
int main(){
    AppleFarmer m;
    int harvest;
    int demand;
    m.AppleFarmer();
    while(m.endOfMonth()==false){
        cout<<"Enter a harvest amount:"<<endl;
        cin>>harvest;
        m.harvestApples(harvest);
        cout<<"Enter a demand:"<<endl;
        cin>>demand;
        m.sellApples(demand);
        cout<<"Apple Inventory: "<<m.getInventory()<<endl;
        m.updateCurrentDay();
    }
    return 0;
}
