i'm making a quick class that has some getters and setters. i'm getting an error at line 46 when i try and create my setItemNumber function. Im also getting an unexpected EOF error but i think that it might have to do with my first error. this is my code....

#include <iostream>
using namespace std;

class Inventory
{
private:
	int itemNumber;
	int quantity;
	double cost;
	double totalCost;
public:
	Inventory();
	Inventory(int,double,int);
	int setItemNumber;
	int setQuantity;
	double setCost;
	double setTotalCost;
	int getItemNumber;
	int getQuantity;
	double getCost;
	double getTotalCost;

};

Inventory::Inventory()
{

	itemNumber = 0;
	quantity = 0;
	cost = 0;
	totalCost = 0;

}

Inventory::Inventory(int n, double c, int q)
{

	itemNumber = n;
	cost = c;
	quantity = q;
	//setTotalCost();

}

void Inventory::setItemNumber(int n)
{

	if(n > 0)
		itemNumber = n;
	else
	{
		cout << "Invalid width\n";
		exit(EXIT_FAILURE);
}

void Inventory::setQuantity(int q)
{

	if(q > 0)
		quantity = q;
	else
	{
		cout << "Invalid width\n";
		exit(EXIT_FAILURE);

}

void Inventory::setCost(double c)
{

	if(c > 0)
		cost = c;
	else
	{
		cout << "Invalid width\n";
		exit(EXIT_FAILURE);

}

void Inventory::setTotalCost(int q, double c)
{

	totalCost = q*c;

}

double Inventory::getCost() const
{

	return cost;

}

double Inventory::getTotalCost() const
{

	return totalCost;

}

int Inventory::getItemNumber() const
{

	return itemNumber;

}

int Inventory::getQuantity() const
{

	return quantity;

}

int main()
{

	Inventory invent;
	int Number;
	int Quant;
	double Cost;
	
	cout << "This program will store data and calculate cost of items.\n";
	cout << "Please enter the number for the item to be bought.";
	cin >> Number;
	cout << "Please enter the quantity of items you want.";
	cin >> Quant;

	invent.setitemNumber(Number);
	invent.setQuantity(Quant);
	invent.setCost(Cost);
	invent.setTotalCost(Quant,Cost);

	cout << "This is the data for the purchase:\n";
	cout << "Item Number: " << invent.getitemNumber() << endl;
	cout << "Item Quantity: " << invent.getQuantity() << endl;
	cout << "Item Cost: " << invent.getCost << endl;
	cout << "Total Cost of your purchase: " << invent.getTotalCost << endl;
	return 0;

}

that was a minor issue but it wasnt my major issue. It had to do when i initially declared my functions. i didnt use a parenthesis. basically i miss declared my functions. thanks though
