    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();
    	};
    
    
    }

    you need to create a "console" application and not a "windows" app.
