Thread: How to use class object in other class

I have some classes and i'm trying to use an Item object in the Shop, I need to setup the items that can be sold but VS keeps giving me errors.

Code:

#include "pch.h"#include <iostream>
#include <string>
#include <map>


class Item
{
    public:
        Item(std::string itemName, int itemBaseValue)
            :    mItemName(itemName), mItemBaseValue(itemBaseValue){}


    protected:
        std::string mItemName;


        int mItemBaseValue;
};


class Player
{
    public:
        std::string GetPlayerName() const
        {
            return mPlayerName;
        }
        int GetPlayerCredits() const
        {
            return mPlayerCredits;
        }


    private:
        std::string mPlayerName;


        std::pair<std::string, int> mPlayerAttackNameAndPower;
        std::map<std::string, int> mPlayerInventory;


        int mPlayerCredits; //Money
};


class Enemy
{
    public:
        Enemy(std::string enemyName, std::string enemyType, std::pair<std::string, int> enemyAttackNameAndPower)
            :    mEnemyName(enemyName), mEnemyType(enemyType), mEnemyAttackNameAndPower(enemyAttackNameAndPower){}
        void GetEnemyName();


    private:
        std::string mEnemyName;
        std::string mEnemyType;


        std::pair<std::string, int> mEnemyAttackNameAndPower;
};


class Shop : public Item
{
    public:
        void CallShop(Item& itemName);
        void CheckPlayerCreditBalance();
        void ProcessTransaction(){}


    private:


};


void Shop::CheckPlayerCreditBalance()
{
    Player player;


    if (player.GetPlayerCredits() >= mItemBaseValue)
    {
        ProcessTransaction();
    }
    else if (player.GetPlayerCredits() < mItemBaseValue)
    {
        std::cout << "You do not posess the credits required to purchase this item, you have:\n";
        std::cout << player.GetPlayerCredits() << " and you need: " << player.GetPlayerCredits() - mItemBaseValue << " credits to purchase this item!\n";
    }
}


void Shop::CallShop()
{
    Item MedKit("Med Kit", 50);


    std::cout << "Welcome to the shop, what would you like to buy?\n";
    std::cout << "1) Med-Kit" << MedKit.mItemName << " C" << MedKit.mItemBaseValue << "\n";


}


int main()
{


    return 0;
}
