#1

#2

please share your code.
thanks

#3

void Kthlevel(Treenode*root,int level)
{
if(level==1)
{
cout<data<<" ";
return;
if(root==NULL)
return;
}
for last level this is not printing

#4

the data variable you are referring in your code, it should be root->data. right?
and if you check root==NULL later, root->data will result in run time error. since you can’t access data of NULL valued pointer.

thanks
