need some help with the friend function that overloads the << operator heres my code thus far....

#ifndef PRODUCT
#define PRODUCT
#include <iostream>
using namespace std;

class CProduct
     int productID;              // 5-digit product ID number
     int manufactureID;           // 4-digit manufacturer's ID
     double price;           // wholesale price
     double markup;          // percent markup from wholesale, .nn

     CProduct(int pID=00000, int mID=0000, double n_price=0, double n_markup=0)   // default and explicit-value constructor
	 double retailPrice();    // RetailPrice Returns the retail price 
                           //  = wholesale price increased by markup

     bool operator<(CProduct x);   // overloaded < operator  
                           // Receives a CProduct object
                           // Returns true iff this product's ID number < 
                           //    the argument's product ID number

     friend ostream& operator<<(ostream& a, CProduct b);   // overloaded friend output << operator	

//----------------heres my cpp file--------------------------
#include "Product.h"
#include <iostream>
using namespace std;

double CProduct::retailPrice()

	return price - (price * markup/100);

bool CProduct::operator<(CProduct x)
	if(productID < x.productID)
		return true;
		return false;

ostream& operator<<(ostream& a, CProduct b)
	a << b.productID;
	a << b.manufactureID;
	a << b.price;
	a << b.markup;

//-----------------------heres my main to test the functions----------------------

#include "Product.h"
#include <iostream>
using namespace std;

int main()
	CProduct product1(12345,1234,25.03,12);//product 1 constr
	CProduct product2(67891,5678,15,35);//product 2 constr
		cout << product1;
	else if(product2<product1)
		cout << product2;
		return 0;

if you see any other problems please let me know

What seems to be the issue? Your output isn't formatted at all, but other than that, I can't discern what your issue may be.

figured it out all i forgot was the "return a;" haha. thanks for looking at my code though
