Create tree from inorder and preorder

#1


why this code is giving segmentation fault

#2

Dakshi… The print function you have written in your code is wrong… Pls use the approach as,
if(root == NULL)
{
return;
}
if(root->left != NULL && root->right == NULL)
{
cout << root->left->data << " => " << root->data << " <= " << “END” << endl;
}
if(root->left == NULL && root->right == NULL)
{
cout << “END => " <data << " <= END” << endl;
}
if(root->left == NULL && root->right != NULL)
{
cout << "END => " << root->data << " <= " << root->right->data << endl;
}
if(root->left != NULL && root->right != NULL)
{
cout << root->left->data << " => " << root->data << " <= " << root->right->data << endl;
}
preOrder(root->left);
preOrder(root->right);

Also I have edited buildtree function of your code as welll… Pls see to it…
