c++ - Printing Tree Vertically -


Any idea how to print a tree like this? 

  2 / \ / \ / \ / \ 7 5 / \ \ / \ 2 6 9 / \ / 5 8 4

Horizontal solution works well because you use deep search (as you've shown) to create a tree from each subtitle. , Which the console aligns well in the form of a line at a time.

The vertical solution is more difficult, because you need to know all the nodes at the end of the tree to calculate the full width. Therefore, you need to analyze the tree, collect data and then start plotting.

The second option, though perhaps not "elegant" (based on definition), would be to use something like a curses library, in which the performance columns and rows have interchangeable concepts.

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
