c - Sizeof pointer differs from its representation with printf? -

-

जब मैं करता हूँ 

  int k = 9; Printf ("sizeof k:% zu \ n", आकारफ (& amp; amp; amp; amp;; k));   
 मुझे आकार  8  के रूप में मिलता है। लेकिन जब मैं  
  प्रिंटफ़ ("p:% p \ n", & amp; amp; k;   
 मुझे  0x7fff57e3ba24  मिलता है। मैं देख सकता हूं कि यह 12 हेक्स नंबर है जिसका अर्थ है (1 हेक्स 4 बीट्स के बाद से) कि सूचक 48 बिट्स पर रखता है जो 6 बाइट्स है।  
 सवाल: क्यों आकार के आकार का प्रिंट 8 सूचक के लिए है, हालांकि इसकी केवल 6 बाइट्स? आपका तर्क यह है कि यदि मैं  
  printf लिखता हूं ("%" डी ", 4);   
 और यह 1 दशमलव अंक प्रिंट करता है, जो संभावित रूप से 1 बाइट में संग्रहीत किया जा सकता है, फिर  sizeof (int)  1 बाइट होना चाहिए।  
 संख्या  0x7fff57e3ba24  समान है  0x00007fff57e3ba24 । सिर्फ इसलिए कि इस प्रकार की संख्या को कम से कम कर सकते हैं, इसका मतलब यह नहीं है कि यह किसी भी कम स्थान पर है।

I'm trying to call the Python using the Java program py4j . I've been installing the plug-in Eclipse and test name Piidvi project. I'm trying to execute the following part of the code found on py4j webpage: Import from py4j.java_gateway to JavaGateway, java_import gateway = JavaGateway () jvm = gateway.jvm java_import (jvm, '' Org.eclipse Kkorkrisorsej. * ") Vrkspes_rut = Jvankresourkesplginkgetvrkspas ().

I have checked that the P4JJ is present in the Jar Eclipse plugin directory. Can anyone help please? I had to install the py4j application

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...

c++ - Qt::make_shared for creating QSharedPtr as std::make_shared for creating std::shared_ptr -

-
As stated in the Barjini Stroustrup's "A Tour of C ++", and a known C ++ 14 practice As such, someone should avoid the naked code in the new and delete . Provides std :: make_shared and std :: make_unique to create smart pointers to store allocated items in the standard library. However, it is not possible to use these routines for non-standard smart pointers, such as QT's own memory management model (with parent), but also smart pointer class like Provides QSharedPointer and QPointer (although later it is not actually a brochure indicator). My question is: Is not it convenient to create Qt analog of std :: make_shared ? To like it, QSharedPtr : Namespace Qt {template & lt; Class T, squares ... Args & gt; QSharedPointer & LT; T & gt; Make_shared (erg & amp; ... args) {return QSharedPointer & lt; T & gt; (New t (std :: forward & lt; ergos & gt; (args) ...)); }} or to create this, QPointer : named place ...
