Question

I want to create a function, that prints output according to its parameter.
Like if I pass a ofstream pointer it should print the output to the respective file, whereas if i pass cout or something, that makes it print to the terminal.

Thanks 🙂

void display(std::ostream& stream)

    stream << "Hello, World!";
}

display(cout);

std::ofstream fout("test.txt");
display(fout);
