operator<< overload,
- by mr.low
//using namespace std;
using std::ifstream;
using std::ofstream;
using std::cout;
class Dog
{
friend ostream& operator<< (ostream&, const Dog&);
public:
char* name;
char* breed;
char* gender;
Dog();
~Dog();
};
im trying to overload the << operator. I'm also trying to practice good coding. But my code wont compile unless i uncomment the using namespace std. i keep getting this error and i dont know. im using g++ compiler.
Dog.h:20: error: ISO C++ forbids declaration of ‘ostream’ with no type
Dog.h:20: error: ‘ostream’ is neither function nor member function; cannot be declared friend. if i add line using std::cout; then i get this error.
Dog.h:21: error: ISO C++ forbids declaration of ‘ostream’ with no type.
Can somebody tell me the correct way to overload the << operator with out using namespace std;
