i am new to c++ and i am currently trying to write a program that uses main to call functions which are seperately written and i tried to write the definitions for the header file declarations and i am getting errors with some functions which i have marked in the code
Store.hpp
#ifndef STORE_HPP
#define STORE_HPP
class Product;
class Customer;
#include<string>
#include "Customer.hpp"
#include "Product.hpp"
class Store
{
private:
std::vector<Product*> inventory;
std::vector<Customer*> members;
public:
void addProduct(Product* p);
void addMember(Customer* c);
Product* getProductFromID(std::string);
Customer* getMemberFromID(std::string);
void productSearch(std::string str);
void addProductToMemberCart(std::string pID, std::string mID);
void checkOutMember(std::string mID);
};
#endif
i am having trouble writing the code for that function help me
store.cpp
#include <iostream>
#include <string.h>
#include "Customer.hpp"

{

inventory.push_back(p);
}
void Store:: addMember(Customer* c)
{
members.push_back(c->getAccountID());
}
Product* Store::getProductFromID(std::string id)
{
for(int i = 0; i < inventory.size(); i++)
{
Product* p=inventory.at(i);
if(p->getIdCode()= id)
{
return p;
}
}
return NULL;
}
Customer* Store:: getMemberFromID(std::string id)
{
for(int i = 0; i < members.size(); i++)
{
Customer* c = members.at(i);
if(c->getAccountID() == id)
{
return c;
}
}
return NULL;
}
void std::Store productSearch(std::string str)
{
for(int i = 0; i < inventory.size(); i++)
{
if(inventory[i] == str)
{
Product stud(inventory[i],inventory[i+1],inventory[i+2],inventory[i+3],inventory[i+4]);
cout<<getIdCode();

}
}
}
void addProductToMemberCart(std::string pID, std::string mID)
{

getMemberFromID(mID)->addProductToCart(pID);
}

You code issues lots of warnings and errors as stands.
If you find yourself in this situation and can't figure out what one of them means, try to fix some of the others.
Your main problem is in addProduct, but there are others
using namespace std;
string id; //<---- what's this for?
void Store::addProduct(Product* p) //error 1 no matching function
{
//Product* p(std::string id, std::string t, std::string d, double p, int qa);
//<--- This line had the error and isn't needed
inventory.push_back(p);
}
void Store::addMember(Customer* c)
{
// members.push_back(c->getAccountID()); //<--- this errors too
members.push_back(c);
}
Product* Store::getProductFromID(std::string id)
{
for (size_t i = 0; i < inventory.size(); i++)
{
Product* p = inventory.at(i);
//if (p->getIdCode() = id) //<-- be careful with = and ==
if (p->getIdCode() == id) //<---
{
return p;
}
}
return NULL;
}
Customer* Store::getMemberFromID(std::string id)
{
for (size_t i = 0; i < members.size(); i++)
{
Customer* c = members.at(i);
if (c->getAccountID() == id)
{
return c;
}
}
return NULL;
}
//void std::Store productSearch(std::string str)
void Store::productSearch(std::string str) // <---- note this change too
{
for (size_t i = 0; i < inventory.size(); i++)
{
//if (inventory[i] == str) //<<--------!
if (inventory[i]->getDescription() == str)
{
//Product stud(inventory[i], inventory[i + 1], inventory[i + 2], inventory[i + 3], inventory[i + 4]);
// This is five Products from the inventory, not the i-th product in your invetory
Product stud(*inventory[i]);//<---- I assume
cout << stud.getIdCode();
cout << stud.getTitle();
cout << stud.getDescription();
cout << stud.getPrice();
cout << stud.getQuantityAvailable();
}
}
}
void Store::addProductToMemberCart(std::string pID, std::string mID)//<--- note note std::Store addProductToMemberCart
{
cout << "adding to cart" << endl;
getMemberFromID(mID)->addProductToCart(pID);
}
void Store::checkOutMember(std::string mID)//<---
{
//Customer* c = getAccountID(mID);//<<---?
//mID = getMemberFromID(std::string mID); //<---?
Customer* c = getMemberFromID(mID); //Just this?
if (c == NULL)//<---rather than "NULL" but nullptr might be better
{ // or not using pointers at all
cout << mID << "is not found" << endl;
}
}
