c++ - accessing protected data members of another class -


I am trying to apply a red-black tree, and I have created nodes, each of which has a left child The node is, the right baby node, and a parent node, stored in my red black node class as safe data members. In my convergence ceremony, I have to use each node-protected member like my left child or his parents, using node -> _ left -> _ guardian and so on. However, my compiler complains that 

  bst.h: 77: 29: error: 'node & lt; Int, int & gt; * Node & lt; Int, int & gt; :: _ left 'is protected rbbst.h: 160: 3: error: within this context bst.h: 77: 46: error:' node & lieutenant; Integer, interval & gt; * Node & lt; Int, int & gt; :: _ parent 'is protected rbbst.h: 160: 3: error: this reference inside

How can I remove this issue?

My suggestions: 1. recode class node as a structure; 2. Add those accessible public members to the brain who return in the context of those data members and you should keep the data member as private;

Finally, sorry for my bad english. This is my first answer on this web site. (● '◡' ●)

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
