Replacement for Console.WriteLine?

I am an experienced C developer, but also a newbie in C++.

I am trying to compile and run the following code snippet on Linux:

FieldIterator   itr = doc.GetFieldIterator();

    while (itr.HasNext()) {
        Field field = itr.Current();
        Console.WriteLine("Field name: {0}", field.GetName());
        itr.Next();
        }

Since my g++ compiler doesn't like the "Console.WriteLine()"
statement, I googled for it, and it seems to be some Windows-specific
construct. What can I use as a replacement?  Obviously, I tried
"printf()" but the argument is not a string.

TIA,
