set intersection - Trouble with set_union and set_intersection - C++ -


I am currently working on a project related to set calculations. I am using the function set_inien and set_insecure to calculate the union and intersection of sets. My variables are: 

  int AunionB [8]; Int Annian Sea [7]; // defined AunionC en BunionD [9]; // Define BunionD int AintersectB [4]; // Define intercact with antentec [3]; // Define Antareskect Set & lt; Int & gt; FinalUnion; // The final team of A, B, C, D set & lt; Int & gt; FinalIntersection; The last interval of A, B, C, D // These sequences of these four sets are respectively union and intersection: set A, set B, set C, and seti my set_union function are as follows:  
  Set_union (AunionC, AunionC + 7, BunionD, BunionD + 9, finalUnion.begin ());  
 
 And my set_intersction function is as follows: 
 
  set_intersection (entersexteb, entersect b +4, antterspectac, extractor + 3, final intrusion. ));  
 
 When I compile, I get the "Required from here" error, which means I'm not sure. Can someone please help me with this? I believe this is something with set_union and set_interscture functions and their parameters, but I'm not sure.

use instead 

  #include & lt; Iterator & gt; // ... set_enian (AunionC, AunionC + 7, BunionD, BunionD + 9, std :: inserter (final Yuanian, finalUnion.begin ()));

and 

  set_intersection (entersexteb, entersch b + 4, anttersx, antercacteq + 3, std :: inseter (final interval, last interaction. )));

A perfect example 

  #include & lt; Iostream & gt; # Include & lt; Algorithm & gt; #include & lt; Iterator & gt; # Include & lt; Set & gt; Int main () {int a [] = {1, 3, 5}; Int b [] = {0, 2, 4, 6}; Std :: set & lt; Integer & gt; S; Std :: set_union (std :: start (a), std :: end (a), std :: begin (b), std :: end (b), std :: inserter (s, s.begin ()) ); (Int x: s) for std :: cout & lt; & Lt; X & LT; & Lt; ''; Std :: cout & lt; & Lt; Std :: endl; Return 0; }

is output 

  0 1 2 3 4 5 6

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. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

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 (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
