I have to create a bst in which i have to add string values in the nodes..I have to display the no of nodes inserted each time..When I insert small string like..FA or B...i am getting the correct value in count[count is the variable which I have taken to count the number of nodes in bst]..But when I enter a larger string value like a2b3bergrk the count is not working properly...its intial value which is set to zero is changed to some garbage value..like 8543245 instead of 0.

void BinarySearchTree::insert(char* d)  
    {
		
            tree_node* t = new tree_node;
            tree_node* parent;
strcpy(t->data,d);
            t->left = NULL;
            t->right = NULL;
            parent = NULL;
          // is this a new tree?
          if(isEmpty()) root = t;
          else
          {
                //Note: ALL insertions are as leaf nodes
                tree_node* curr;
                curr = root;
                // Find the Node's parent
            while(curr)
            {
                parent = curr;
                if(strcmp(t->data,curr->data)>0) curr = curr->right;
                else curr = curr->left;
            }

            if(strcmp(t->data,parent->data)<0)
                   parent->left = t;
            else
                   parent->right = t;
          }
		 
		  cout<<count<<endl;
		  
          count++;
		  
    }

Need to know the definition of the

  • string input variable
  • string variable in the node
  • value being set to 0
  • count value
  • node itself
