        objectA() : nA(12) {}
        
    private:
        int nA;
        
         
         friend int subtract(objectA, objectB);
};


class objectB {


    public:
       
        objectB() : nB(6) {}
    
    private:
        int nB;
 
        
        friend int subtract(objectA, objectB);
};
class objectC{
	friend int subtract(objectA, objectB);
};


int subtract(objectA objA, objectB objB) {
    return (objA.nA - objB.nB);
}


int main() {
