operator<<

[mickey]

Hello,
could anyone at first sight tell me about why this below doens't work with keyword "const" (that I guess the right way) and it works without it? thanks

friend std::ostream& operator<<(std::ostream& os, const Apple& a) { // <- "const"
		return os << "kind = " << a.getKind().c_str() << "\t" 
                  << "weight = " << a.getWeight() << "\t" << "status = " << a.getStatus().c_str() << endl;
	}

friend std::ostream& operator<<(std::ostream& os, const Apple& a) { // <- "const"
		return os << "kind = " << a.getKind().c_str() << "\t" 
                  << "weight = " << a.getWeight() << "\t" << "status = " << a.getStatus().c_str() << endl;
	}
