Edited Java add digits of 4 numbers -

-

I want to add 4 digits of 1 or 2 digits using Java. 

  I1 = 2 i2 = 33 i3 = 12 i4 = 10

Result: 12 (2 + 3 + 3 + 1 + 2 + 1 + 0 )

How can I do this?

Here are some pointers you can give:

1) Code> / which are integers on those arguments, then your result will also be integer

example: 

  int x = 7/2; Println (x);

Output: 3 (not 3.5 )

Then get rid of the last digit of the integer Everyone can, this number is divided by 10 

  int x = 123; X = x / 10; Println (x); There is also a modulo operator in Java that gives a reminder from the partition, like  7 / 2 = 3  and  1  will be the reminder this operator %  
 
 example 
 
  int x = 7 ; X = x% 5; Println (x);  
 
 Output:  2  because  7/5 = 1 (2 relics)  
 
 For integer you can use just like % 10  like 
 
  int x = 123; Int lastDigit = x% 10; Println (lastDigit);  
 
 Output:  3  
 
 Now try to combine this knowledge. Get the last point of the number, add it to the sum, remove this last digit (there will be no number until repeat again).

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
