c++ - fstream and ofstream -


इसमें क्या अंतर है: 

  fstream texfile; textfile.open ( "test.txt");   
 और  
  ऑफस्ट्र्रीम टेक्स्टफ़ाइल; textfile.open ( "test.txt");   
 क्या उनका कार्य समान है?   
 
 
  ऑफस्ट्र्रीम  केवल आउटपुट के लिए तरीके हैं, उदाहरण के लिए यदि आपने  textfile & gt; & gt; जो भी  यह संकलन नहीं करेगा। इनपुट और आउटपुट के लिए  fstream  का उपयोग किया जा सकता है, यद्यपि काम करने वाला यह कन्स्ट्रक्टर /  open ।  
  स्टड :: स्ट्रिंग एस; Std :: ofstream ostream ("फ़ाइल"); Std :: fstream स्ट्रीम ("फ़ाइल", stream.out); ओस्ट्रीम & gt; & gt; रों; // कंपाइलर त्रुटि स्ट्रीम & gt; & gt; रों; // कोई संकलक त्रुटि नहीं है, लेकिन कार्रवाई विफल हो जाएगी।   
 टिप्पणियों में कुछ और महान बिंदु हैं।

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

I am using JPA 2.0 and getting the following code in the DAO layer: Public Zero Test () {string key = "status"; String [] Conditions = {"A", "B"}; & Lt; TestTable & gt; Results = Search (Keys, Conditions); } Public listing & lt; TestTable & gt; Search (string key, object value error) {string sql = "test ndf to testlet and jade nand." + Key + "in:" + key; TypedQuery & LT; TestTable & gt; Query = entityManager.createQuery (SQL, TestTable.class); Query.setParameter (key, Arrays.asList (valueArr)) / *** Error Line *** Return query.getResultList (); } In the above error line, it throws the following exception: java.lang.IllegalArgumentException: parameter value element [[Ljava.lang.String; @ cbe5bc] did not match the expected type [java.lang.String] Why is this expected type string while actually this string []?

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
