initialize a binary tree within a menu

[uytoor2]

i have been asked to provide a menu in which we have to initialize upon pressing 1 in a binary search tree... now i know that we cannot initialize the template class object within a conditional statement .. please tell me a way to tackle this problem .

here is my binary tree class

  template<class T>
class node
{
	public:
	T data;
	node<T> *left,*right;
    node()
	{
	  left=right=0;
	}
};

template<class T>
class tree
{
	public:
	node<T> *root;
	tree()
	{
		root=0;
	}
};
	

i need something like this

if(choice==1)
{
tree<int> obj;
}
