Newline in constant? Overloading the << operator

[struntz]

hello everyone!
I'm getting back into programming once again! wee.
Okay, anyways, I was trying to overload the ostream operator << so i could output my Complex numbers by using, Complex x(3,4); cout <<"x=" << x << endl;
so here is my Complex.h

//complex.h

class Complex
{
	friend ostream& operator<<(ostream &ostrm, const Complex& x);
	friend istream& operator>>(istream &istrm, const Complex &x);
	int top;
	int bottom;
	//constructors
public:
	Complex(int x = 0, int y = 1)
	{ top = x; bottom = y;}
	
	//copy constructor
	Complex(Complex &x)
	{
		top = x.top;
		bottom = x.bottom;
	}




Complex operator +(const Complex &b)
{
	Complex c;
	c.top = top + b.top;
	c.bottom = bottom + b.bottom;
	return c;
}

Complex operator -(const Complex &b)
{
	Complex c;
	c.top = top - b.top;
	c.bottom = bottom - b.bottom;
	return c;
}

Complex operator *(const Complex &b)
{
	return (Complex(top * b.top, bottom * b.bottom));
}

void operator+=(Complex &b)
{
	top = top + b.top;
	bottom = bottom + b.bottom;
}

void operator+()
{
	cout << top << "\\" << bottom << endl;
}


};


//friend functions

ostream& operator<<(ostream &ostrm, const Complex &x)
{
	return ostrm << x.top << '\' << x.bottom;  //error here
	
}


istream& operator>>(istream &istrm, const Complex&x)
{
	cout << "Enter numerator: ";  istrm >> x.top;
	cout << "Enter denominator: "; istrm >> x.bottom;
	return istrm;
}

here are my errors:
--------------------Configuration: ComplexII - Win32 Debug--------------------

Any idea of what i'm doing wrong?
Thanks!
