usually :

 C++ Syntax (Toggle Plain Text) 
std::ostream& operator <<(std::ostream& ostrm)
{
    ostrm << "Hello its overloaded\n";
   return ostrm;
}
std::istream& operator >>(std::istream& istrm)
{
   cout<<"Enter a number  :  ";
   istrm >> MyClass::myNumber;
 
    return istrm;
}
std::ostream& operator <<(std::ostream& ostrm)
{
    ostrm << "Hello its overloaded\n";
   return ostrm;
}
std::istream& operator >>(std::istream& istrm)
{
   cout<<"Enter a number  :  ";
   istrm >> MyClass::myNumber;

    return istrm;
}

note overloading the << operator should be a friend, so you can use it like this :

cout << myClassVar;

if not then you would use this syntax :

myClassVar <<cout;

which is confusing.
