Hi folks,

I am new to C++ and have a question.

I have a class BST:

template <typename Datatype> class BST
{
...
...
}

BST has three data members:

Node * root (Node is defined within BST as a private class)
int size (default is 0)
queue<Datatype> aQueue (default is NULL)

How shall I write the constructor? (code below is provided, I need to add size and aQueue)

template <typename DataType>
inline BST<DataType>::BST()
: root(0)
{    
}

Thanks

You can initialize size the same way you initialize root.  For example:

: root(0), size(0)

A queue can't be NULL.  It is empty when constructed by default, so if that is acceptable, you don't need to do anything to initialize it.
