Programming help

[DarkKnight]

here is an rar with my code

for my compsci class I'm working on inheritence and in this probject there is a Base class Event whose derived classes are TimedEvent and TeamEvent. My problem is when it outputs a timeevent or teamevent to the ostream, it only outputs the Event info and not the TimeEvent or TeamEvent information, even though the writeout function (output function) is virtual. Can someone with programming experience plz look over my code to see whats wrong?

I'm not going to buy winrar to help you with your homework.

Post the code if you want help

Isn't there an evaluation version you can use?

Yes, however, the point is to make it easy for people to assist OP.

If the amount of code is too large, then the OP should trim it down to the problem area.

output <<"none" << endl;
return output;
}


TimedEvent and TeamEvent are also the same and both show the same problem, so i didnt include it
The outputing of TeamEvent and TimedEvent are called in BST.cpp in the print functions

BST.cpp
----------
//this function prints out the elements of the binary search tree in
//lexicographical order
template <class BSTData, class BSTDataKey>
void BST<BSTData, BSTDataKey>:rintForward(ostream &amp;output,
string option) const
{
output <<"**************** Printing Forward ****************";
printInOrder(root, output, option);
output <<"************** End Printing Forward **************"<<endl;
}

//this function prints out the elements of the binary search tree in
//reverse lexicographical order
template <class BSTData, class BSTDataKey>
void BST<BSTData, BSTDataKey>:rintBackward(ostream &amp;output,
string option) const
{
output <<"**************** Printing Backward ****************";
printInReverse(root, output, option);
output <<"************** End Printing Backward **************"<<endl;
}

//prints out the elements of the Binary search tree in alphabetical order
template <class BSTData, class BSTDataKey>
void BST<BSTData, BSTDataKey>:rintInOrder(BSTNode<BSTData> *root,
ostream &amp;output, string option) const
{
if (root->left != NULL)
printInOrder (root->left, output, option);
if (root != NULL &amp;&amp; (option == "All" || option==root->data->classType()))
{
output << endl<<root->data->classType();
output << endl<<*root->data;
}
if (root->right != NULL)
printInOrder(root->right, output, option);
}

//prints out the elements of the Binary search tree in reverse alphabetical
//order
template <class BSTData, class BSTDataKey>
void BST<BSTData, BSTDataKey>:rintInReverse(BSTNode<BSTData> *root,
ostream &amp;output, string option) const
{
if (root->right != NULL)
printInReverse (root->right, output, option);
if (root != NULL &amp;&amp; (option == "All"||option == root->data->classType()))
{
output << endl<<root->data->classType();
output << endl <<*(root->data);
}
if (root->left != NULL)
printInReverse(root->left, output, option);
}

Yes, however, the point is to make it easy for people to assist OP.

A facility exists for the code to be made visible.

If the amount of code is too large, then the OP should trim it down to the problem area.

Oh, yeah, I agree with you completely... I wasn't trying to say that notfred should have to deal with the burden of downloading a prog to help someone else with their hw, but rather just to point out that you don't have to pay for WinRAR.

And that is the reason for the first word of my response.
