c - What is the difference between static const and const? -


संभव डुप्लिकेट:

स्थिर const और const के बीच अंतर क्या है? उदाहरण के लिए: <पूर्व> स्थिर const int = 5; Const int i = 5;

क्या उनके बीच कोई अंतर है? आप दूसरे पर एक का उपयोग कब करेंगे?

अंतर लिंक है। 

  // फ़ाइल गुंजाइश पर स्थिर const int = 5; // आंतरिक लिंकेज सीआर int i = 5; // बाह्य संबंध   
 यदि  i  ऑब्जेक्ट अनुवाद यूनिट के बाहर प्रयोग नहीं किया जाता है, जहां इसे परिभाषित किया गया है, तो आपको इसे  स्थिर  स्पेसिफायर।  
 इससे संकलक को (संभावित रूप से) अधिक अनुकूलन करने में सक्षम बनाता है और पाठक को सूचित करता है कि ऑब्जेक्ट को इसके अनुवाद इकाई के बाहर प्रयोग नहीं किया जाता है।

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
