unable to output string?

Code:

---

        void write_on_paper(string words)
        {
                if (InkLevelPercent <=0)
                {
                        cout << "Oops! Out of ink!" << endl;
                }
                else
                {
                        cout << words << endl;
                        InkLevelPercent = InkLevelPercent - words.length();
                }
        }

The error code is referring to

I'm still learning C++ and this is an example from the book. But it won't compile. can anybody help please? thanks in advance.

Nevermind i found my issue my compiler doesn't include string in the std namespace. i needed to include <string>

What header files did you include?

Those functions and classes are declared in their appropriate #include files, so that code is not complete unless you post what files are included.
