    Exclamation Displaying values from one class in another...

    I've created these two classes and I have to display the information that is in the first class. I am unsure as how to do this since it is contained in the private part of the class. I want to go and display the cPRODUCT's private info in the cINVENTORY class's addProduct() method.

    Code:
    #include <iostream>
    #include <string>
    using namespace std;
    
    class cPRODUCT
    {
    	private:
    		long nSerialNum;
    		string ProductDesc;
    		float fWholesale;
    		float fRetailcost;
    		int nInStock;
    	public:
    		cPRODUCT(void) 
    		{ 
    			nSerialNum = 0;
    			ProductDesc = "";
    			fWholesale = 0;
    			fRetailcost = 0;
    			nInStock = 0;
    		}
    		void enterProdInfo(void)
    		{
    			const int MINIMUM_SERIAL_NUMBER = 100000;
    			const int MAXIMUM_SERIAL_NUMBER = 999999;
    			cout << "Please enter the product's six digit serial number: ";
    			cin >> nSerialNum;	
    
    			cout << "Please enter the product description: ";
    			cin >> ProductDesc;
    
    			cout << "Please enter the wholesale price: ";
    			cin >> fWholesale;
    	
    			
    			cout << "Please enter an appropriate amount: ";
    			cin >> fWholesale;
    			}	
    
    			cout << "Please enter the number of items in stock: ";
    			cin >> nInStock;
    		}
    		float calcRetail(void)
    		{	
    			return fRetailcost;
    		}
    		void displayProd(void)
    		{
    			cout << ProductDesc;
    		}
    		float getWholesale(void)
    		{
    			return fWholesale;
    		}
    		int getInStock(void)
    		{
    			return nInStock;
    		}
    		bool isExpensive(void)
    		{
    		}
    };
    Code:
    #include <iostream>
    #include <string>
    using namespace std;
    
    class cINVENTORY
    {
    	private: 
    		cPRODUCT Products[100];
    		short nNumProdTypes;
    		float fTotalWhole;
    		float fTotalRetail;
    		int nOverallItems;
    	public:
    		cINVENTORY(void)
    		{
    			Products[100];
    			nNumProdTypes = 0;
    			fTotalWhole = 0;
    			fTotalRetail = 0;
    			nOverallItems = 0;
    		}
    		void addProduct(int* i, float* fTotalWhole)
    		{
    			float fWholesaleCost = 0;
    			
    			//Fill the Products array
    			Products[*i].enterProdInfo();
    			nNumProdTypes++;
    
    			//Do Calculations (Total Wholesale, Retail, and InStock)
    			fWholesaleCost = Products[*i].getWholesale();
    			*fTotalWhole += fWholesaleCost;
    		}
    		void resetInventory()
    		{	
    		}
    		void displayInventory(int* i)
    		{
    		}
    };
    I really appreciate any help you guys can give.

    Thanks,

    ...Dan

    Can't you just create a display member function in cProduct and call that from cInventory?
    Code:
    for (int i=0; i<nOverallItems; i++)
    {
       Products[i].Display();
    }

    i keep on missing these simple solutions, lol. Thanks for the help. First time with classes, so hard to get used to the whole private, public thing.
