C - Swapping nodes in a linked list with a sorting algorithm -


I am working on a project for school where I need to sort a linked list with a sorting algorithm (preferably bubbles) - please -

Note that swapping of each node data is not allowed because I hope to swap nodes. I can not paste all the code in my project because it is very detailed and it is in Spanish, due to which I will show you the parts in which I try to implement the nodes swapping.

, the project is very simple, a linked list where every node has information about a person (name, last name, age, etc.).

I have to sort the alphabetical order according to the list. Please keep in mind that I can not implement the swapping algorithm in sorting and functioning (to say that, I can not create the 'swapnod' function and in the code

I have been successful in swapping two nodes after this argument: 

  firstNode = auxiliar-> next; auxiliar-> gt; next = first Node-> next; first node-> gt; next = auxiliar;

this completely 2 nodes Works for swapping.

The problem is that when I sort all the lists with a sorting algorithm to sort this list, people help me.

I have seen every post about swapping of bubbles coating and node, but I can work on it.

My professor tried to help me, implementing my node swapping code In the following ways (please pay attention to Does that as an example, should be in accordance with the age of the following code): 

  while (flag == 1) {auxiliar = firstNode; Flag = 0; If (auxiliar- & gt; Idad & gt; auxiliarSiguiente- & gt; E-father) {firstNode = auxiliar-> Next; Auxiliar- & gt; Next = firstNode-> next; FirstNode-> gt; Next = auxiliar; Flag = 1; } Auxiliar3 = firstNode; While (auxiliar-> Next! = Null) {if (auxiliar-> gt; age> auxiliarNext-> gt; age) {auxiliar2 = auxiliar- & gt; next; Next-> Next = auxiliar2-> next; Auxiliar2- & gt; Next = auxiliar; Auxiliar3- & gt; Next = auxiliar2; } And (auxiliar = auxiliar-> Next;} Auxiliar3 = auxiliar3-> Next;}}

And then, this code works fine when there are 2 nodes Besides, it does not sort correctly. Besides, I'm not completely sure what my professor uses algorithm.

Maybe what my teacher has done, or maybe doing this

I appreciate you very much

Itemprop = "text"> < P> Your original swap code does not change the next indicator of the node that indicates pointing node auxiliar before swap (which will be If auxiliar is not the first node in the list).

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added.

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

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date ().
