hi,
do we have any class or library that support the binary trees data structures. what about three ways of traversing. I searched google but I am not convinced based on search result. can someone help me please?
|

You can find the three basic ways of searching a binary tree in most introductory books on data structures. They are: preorder, inorder, and postorder. Your instructor probably covered these in a lecture.

he did covbered in lectures in c language but I do assignment in Csharp sp to make the assignment I need to have already a class that stores the data in a binary tree fashion. do we have any built in or already written class by others. yes, Once I have that I can write a recirsive routine to do the type of traverses u mentioned above.

You need to understand the algorithm to store data in a binary tree. It's not hard. Once you understand this, you can write the code yourself.

Hi,
I'm writing an application in which I'm currently using Console.Writeline() calls to output the various stages. This helps me to develop and debug as I go. However, the time will come when I want to remove all such calls. Can anyone suggest some advice, an article (I have searched on CP) or other source which will tell me how to use debug statements in code which I can then switch off for release.
I was thinking of a logging class - in debug mode it would write to the console but in release mode it would write certain information to a file. The Console.Writeline() methods allows me to do the following:
Console.Writeline("Val1 {0}, Val2 {2}", val1, val2);
How could I write my own function which would accept an unknown number of parameters like this? I would like my function to pass the parameters directly to Console.Writeline() or to a file depending on a flag.
Thanks for any help offered

Wrap them in #if DEBUG blocks.
#if DEBUG
Console.WriteLine("Debugging");
#endif

Replace Console.Writeline with Debug.Writeline...
If you do a Release build, the calls to the Debug.Writeline should not be included in the executable.

I don't know about that. I would think the calls to Debug.WriteLine, or anything else in the Debug class, would be left out though. Console, I think, stays around, even though it's a Windows Forms app.

Yup. It is the Debug class. Got my wires crossed there for a moment

Hi,
I am trying to write a code that gets all the files in a folder and returns the name of the file that has the most recent "write" date.
i have wrote this function that gets "path" and should return fileName string.
string[] fileNames = Directory.GetFiles(filePath); // get file names in array
string[] fileDatesList = fileNames; // create fileDateList and initialze(not relevant with what
for (int i = 0; i < fileNames.Length; i++)
{
fileDatesList[i] = Directory.GetLastWriteTime(fileNames[i]).ToString();
}
//TODO write the return(
my problem is with this line:
fileDatesList[i] = Directory.GetLastWriteTime(fileNames[i]).ToString();
lets say i have 3 files in a folder:
abc00, abc01, abc02.
fileNames string array gets all 3 names and stores them.
when i get to the fileDatesList in the for loop, all the entities in
fileNames array are CHANGED with the Date of the file...
example:
before for loop:
fileNames=[abc00,abc01,abc02]
fileDatesList=[abc00,abc01,abc02]
step i=0:
fileNames=[18/11/2008 4:25PM,abc01,abc02]
fileDatesList=[18/11/2008 4:25PM,abc01,abc02]
and so on untill both have only date and time...
i don't understand why it does that why it changes fileNames while changing fileDatesList... although i am not assigning fileDatesList to fileNames in anywhere out of the getLastWriteTime...
thanks a lot!

string[] fileDatesList = new string[fileNames.Length];

This is your problem. You think that declaring a variable that is a reference to a string array does also create an array of strings, but it doesn't. You end up with two references to the same array of strings. Anything that you do to the array through one of the references is what you see when you access the array through the other reference.
You have to create a new array, so that you have two separate arrays:
string[] fileDatesList = new string[fileNames.Length];
Despite everything, the person most likely to be fooling you next is yourself.

I learn best by doing. I can read a book or sit in a class, but it's when I have to actually sit down and type the code in that I learn best.
So can anyone point me to a few websites (or projects/articles HERE) that might be geared toward this type of learning? You know, some C# project from start to finish? Maybe some dif't levels, starting at simple and working up to harder projects?
I have a programming background and experience w/ Microsoft products and even some .NET. It's just hard to be motivated on this project at the moment and I think this is what I need to kickstart it.
Thanks, all.
P.S. My latest project is a simple .NET web interface to:
allow user input
to a SQL Server backend and
generate some reports,
so something along those lines would be IDEAL
Edit: not really looking for beginner "tutorials" such as Quick C#... I have books that show syntax, and I already have a feel for the language... I need to figure out how to put it all together.

Pick something that will give you a sense of accomplishment when it's done. This will motivate you to finish it.

I lost interest in your message when I saw this:

I never rest. I knew what he meant (obviously), but I stand by my assertion that I am apathetic to his question due his lack of respect for those of us with a proper education.
Oh yeah, and who the hell are you, Member 5646867? If you're not willing to use a proper user ID, you haven't earned the right to call me by my first name.
