String is not recognized?

Here is my main function:

Code:

---

/* CSE 231  Project 5 Solution
        This file simulates the madlib game by reading a user inputted
        file which contains the story line embedded with #XXXX#.
*/

#include <iostream>
#include <string>
#include <fstream>
#include "Madlibs.h"

using namespace std;

int main ()
{
        string filename, line;
        ifstream inFile;
        Madlibs story;

        cout << "Enter the name of the file containing the paragraph --> ";
        cin >> filename;
        inFile.open(filename.c_str(), ios::in);

        if (inFile.fail())
        {
                cerr << "\n** Unable to open input file - " << filename << " **\n\n";
        }
        else
        {
                while (!inFile.eof())
                {
                        getline(inFile, line, '\n');
                       
                        story.createStory(line);
                }
                story.display();
        }
       
        inFile.close();
       

        return 0;
} // end of main

---

And here is my header file:

Code:

---

#ifndef MADLIBS_H
#define MADLIBS_H

#include <string>

class Madlibs
{
public:
        //Constructor
        Madlibs();

        //Function to display
        void display();

        //Function to create the Story
        string createStory(string s);

private:
        string word;
        string sentence;
};

#endif

---

And I think it should work, but I'm getting these errors:

Code:

---

Please help!!

Code:

---

#ifndef MADLIBS_H
#define MADLIBS_H

#include <string>

class Madlibs
{
public:
        //Constructor
        Madlibs();

        //Function to display
        void display();

        //Function to create the Story
        std::string createStory(std::string s);

private:
        std::string word;
        std::string sentence;
};

#endif

thanks

or, you could use using namespace std;

but in this case, Jawib's suggestion is much better.

or you could find a midground: put 'using std::string;' at the top...
