чет все делают свою обертку над cout
cout просто частный случай
AB

AB
Разве что в сериализаторах

#include <iostream>
#include <fstream>
using namespace std;
class Foo
{
};
ostream& operator<<(ostream& os, const Foo& f)
{
os << "Foo to screen";
return os;
}
ofstream& operator<<(ofstream& ofs, const Foo& f)
{
ofs << "Foo to file";
return ofs;
}
int main()
{
Foo f;
cout << f;
ofstream file("file.txt");
file << f;
file.close();
return 0;
}

std::istream& operator << (std::istream&, YourType const&)
RN
