क्या कक्षा कोई ऑब्जेक्ट है, या यह एक स्ट्रेट है?

उद्देश्य- C कक्षाओं को कुछ प्रतिबंधों के साथ वस्तुओं के रूप में माना जाता है (देखें):

कक्षा ऑब्जेक्ट्स इस प्रकार पूर्ण रूप से विकसित वस्तुओं को गतिशील रूप से टाइप किया जा सकता है, संदेश प्राप्त कर सकते हैं, और अन्य वर्गों से वारिस के तरीकों वे केवल उस विशेष में हैं, जिन्हें वे कंपाइलर द्वारा बनाए गए हैं, उनकी कक्षा के परिभाषा से निर्मित डेटा संरचनाओं (उदाहरण चर) की कमी है, और रनटाइम पर इंस्टेंसेस बनाने के एजेंट हैं।

दृश्य के पीछे, एक वर्ग की परिभाषा में विभिन्न प्रकार की जानकारी होती है, इनमें से अधिकांश वर्ग के उदाहरणों के बारे में:

  • वर्ग और इसके सुपरक्लास का नाम
    • < Li> एक उदाहरण उदाहरण चर का एक सेट वर्णन
  • विधि नामों की घोषणाएं और उनकी वापसी और तर्क प्रकार
  • विधि कार्यान्वयन

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa...
