c - getchar gives output in the wrong order -

-

प्रोग्राम को निम्न तरीके से आउटपुट देना चाहिए:

एक वर्ण डालें

जी

सफलतापूर्वक प्रवेश किया!

जी 

  #include & lt; stdio.h & gt; Int main () {int c, d; Printf ("एक चरित्र दर्ज करें \ n"); C = getchar (); Printf ("सफलतापूर्वक प्रवेश किया! \ N"); putchar (ग); वापसी (0); }   
 लेकिन जब इसे चलाया जाता है, तो यह उपयोगकर्ता के लिए पूछने से पहले इनपुट दर्ज करने की प्रतीक्षा करता है और फिर निम्न तरीके से प्रिंट करता है:  
 g  
  
 जी   
 
 
 आप getchar से पहले printf के बाद fllush डाल सकते हैं  
  printf (" एक चरित्र दर्ज करें \ n "); fflush (stdout); C = getchar ();   
 एफflush को आउटपुट स्ट्रीम पर कॉल किया जाना है। यह सी मानक से एक उद्धरण है:  
  int fflush (FILE * ostream); ऑस्ट्रीम पॉइंट को आउटपुट स्ट्रीम या एक अपडेट स्ट्रीम में इंगित करता है जिसमें सबसे हालिया ऑपरेशन इनपुट नहीं था, फ़्लेमफ़िश फ़ंक्शन फ़ाइल को लिखे जाने के लिए मेजबान पर्यावरण को वितरित करने के लिए उस स्ट्रीम के किसी भी अलिखित डेटा का कारण बनता है; अन्यथा, व्यवहार अपरिभाषित है।

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
