Can't get rid of trash while overloading operator << in C++ - c++

Question

class point //declaration of class
{
private:
int x, y;
friend std::ostream &operator << (std::ostream &input, point &p);
public:
//constructors and some other methods
};
//definition of overloading <<
std::ostream &operator << (std::ostream &input, point &p)
{
input << std::cout << "x = " << p.x << " y = " << p.y << " ";
return input;
}
And it works but when I use it
std::cout << object;
it shows some trash before my text:
062ACC3E8x = 1 y = 22
So 062ACC3E8X is something that always appears. It is defferent if I restart Visual Studio which I'm working on, so I suppose It's some memory adress. How to get rid of it? Is it something missing or wrong in my code?

Answer 1

You output some adress, since std::ostream has implicit void* conversion operator.
1) Returns a null pointer if fail() returns true, otherwise returns a
non-null pointer. This pointer is implicitly convertible to bool and
may be used in boolean contexts.
Should be just
input << "x = " << p.x << " y = " << p.y << " ";

Answer 2

You are passing std::cout into your output stream. Change your code to:
//definition of overloading <<
std::ostream &operator << (std::ostream &input, point &p)
{
input << "x = " << p.x << " y = " << p.y << " ";
return input;
}
