Thread: Linking Errors

I got the program to work that i was using and then I decided to make another version of it where it will go through the process multiple times. I compile it and get no errors, but when i go to run it, i get these errors.

error LNK2001: unresolved external symbol _WinMain@16

fatal error LNK1120: 1 unresolved externals

heres the code.

Code:

#include<iostream.h>

class GroceryItem
{
	private:
		int stockNum;
		double priceEach;
		int quantity;
		double totalValue;
		void calculateTotalValue(double, int);
	public:
		void setStockNum();
		void setPriceEach();
		void setQuantity();
		void setGroceryVariables();
		void displayGroceryItem(int, double, int, double);
};

void GroceryItem::setStockNum()
{	
	cout<<"Enter the Stock Number: ";
	cin>>stockNum;

};
void GroceryItem::setPriceEach()
{
	cout<<"Enter the price: ";
	cin>>priceEach;
};
void GroceryItem::setQuantity()
{
	cout<<"Enter the quantity in stock: ";
	cin>>quantity;
};
void GroceryItem::calculateTotalValue(double, int)
{
	totalValue=priceEach*quantity;
};
void GroceryItem::displayGroceryItem(int, double, int, double)
{
	cout<<"Item #"<<stockNum<<" Price: "<<priceEach<<endl;
	cout<<"Quantity in stock: "<<quantity<<" Value: "<<totalValue;
};
void GroceryItem::setGroceryVariables()
{
	setStockNum();
	setPriceEach();
	setQuantity();
	calculateTotalValue(priceEach, quantity);
	displayGroceryItem(stockNum, priceEach, quantity, totalValue);
};
int main()
{

	int num;
	GroceryItem anItem;
	for (num=1; num<3; ++num)
	{
		anItem.setGroceryVariables();
	};


}

stupid me, i didn't notice that i made it an win32 app.. thanks. i would have never figured that out. heh
