Ofstream... broke as a result of ifstream fix

Now I'm having troubles with writing the file out. I'M SO CLOSE to finishing this assignment!

OK, here is my call to the function:

Code:

---

case 5: cout << "Enter the name of the File to save to:" << endl;
                                getline(cin, nameOfFile);
                                entry.writeToFile(nameOfFile);
                                break;

---

Here is my function writeToFile():

Code:

---

void AddressBook::writeToFile(string fileName)
{
        ofstream outfile;
       
        outfile.open(fileName.c_str());
        if(!outfile)
        {
                cout <<"Cannot write to the file" << endl;
        }
        addressTree->writeFile();
        outfile.close(); 
}//end writeToFile

---

That function calls the following in my binary tree file:

Code:

---


template< typename NODETYPE >
void Tree< NODETYPE >::writeFile() const
{
        ofstream out;
        writeFileHelper(out, rootPtr);
}//end function writeFile

template< typename NODETYPE >
void Tree< NODETYPE >::writeFileHelper(ofstream& out, TreeNode< NODETYPE > *ptr ) const
{
        ofstream outfile;
  if ( ptr != 0 )
  {
      writeFileHelper(out, ptr->leftPtr ); // traverse left subtree 
      outfile << ptr->data; // process node               
      writeFileHelper(out, ptr->rightPtr); // traverse right subtree
  } // end if
} // end function inOrderHelper
//  function to perform deleteFromTree

---

The writeToFile worked before I changed the ifstream, but now I've been messing with it trying to get it to work. I get this error message:

:\program files\microsoft visual studio\myprojects\bst addressbook\tree.h(29) : error C2061: syntax error : identifier 'ofstream'
c:\program files\microsoft visual studio\myprojects\bst addressbook\tree.h(31) : see reference to class template instantiation 'Tree<NODETYPE>' being compiled
c:\program files\microsoft visual studio\myprojects\bst addressbook\tree.h(97) : error C2061: syntax error : identifier 'ofstream'
Error executing cl.exe.

any ideas?

This is so great, that there are people who can help. I hope I can do it at some point!

Thank you for helping.

Note sure what is the cause of the error, but have you tried fully qualifying ofstream? It makes sense to use std::ofstream instead of ofstream in a header file since you would want to avoid propagating a namespace collision from a header file.

Incidentally, I thought that it makes more sense for writeFile() to take a std::ofstream& parameter, at least from what I understand of the code.

Maybe include ofstream ?
Maybe write std::ofstream out;
When does this file get opened ?

> ofstream outfile;
Now you have both out and outfile.
Neither of them seem to be initialised.

Thank you thank you thank you!
