inheritence & overloaded operators

[Imajica]

I have to write a program using inheritence & the overloaded << operator, how do you call the base class functions output stream from the derived class?

For example, to do a print from class base via a derived class

void derived::print()
{
base::print()
}

works, the same syntax with overloaded << does not.

I am clueless on this.

Operators can be called in one of two ways.

If for instance, I have a class A that overloads << for output streams, like so:

code:

#include <iostream> class A {    public:    friend std::ostream& operator<<(std::ostream&, const A&); }; int main() {    A myVar;    std::cout << myVar;    // is the same as...    operator<<(std::cout, myVar); } std::ostream& operator<<(std::ostream& out, const A& a) {    return out << "hello world!"; }
