[RESOLVED] at a loss with overloading opperators

[austinm6]

friend ostream& operator<<(ostream& ostm, const Mixed& m);
	friend istream& operator>>(istream& istm, Mixed& m);
	friend bool operator<(const Mixed& lhs, const Mixed& rhs);
	friend bool operator>(const Mixed& lhs, const Mixed& rhs);
	friend bool operator<=(const Mixed& lhs, const Mixed& rhs);
	friend bool operator>=(const Mixed& lhs, const Mixed& rhs);
	friend bool operator==(const Mixed& lhs, const Mixed& rhs);
	friend bool operator!=(const Mixed& lhs, const Mixed& rhs);
    friend Mixed operator+(const Mixed& lhs, const Mixed& rhs);
    friend Mixed operator-(const Mixed& lhs, const Mixed& rhs);
    friend Mixed operator*(const Mixed& lhs, const Mixed& rhs);	 
    friend Mixed operator/(const Mixed& lhs, const Mixed& rhs);	 
    friend Mixed operator++(Mixed& m, int);
    friend Mixed operator++(Mixed& m);
    friend Mixed operator--(Mixed& m, int);
    friend Mixed operator--(Mixed& m);

i keep getting errors with all 6 with bool when i dont comment them out in the driver if you need my .h and 2 .cpp files let me know! thank you!
