c++ - A little problem in handling 2-D arrays with class - 


  वर्ग linklist4x4 {निजी: struct node4x4 {दोहरे डेटा [4] [4]; नोड 4x4 * लिंक; } * पी; सार्वजनिक: linklist4x4 (); शून्य संलग्न (डबल * अंक); शून्य add_as_first (डबल * संख्या); शून्य ऐडफेर (इंट सी, डबल * अंक); // void del (डबल * num); शून्य प्रदर्शन (); पूर्णांक संख्या (); डबल * getdata (int c); ~ Linklist4x4 (); };

उपरोक्त मेरा वर्ग घोषणा है।

अब नीचे एक फ़ंक्शन घोषणा है। 

  शून्य linklist4x4 :: append (डबल * Num) {node4x4 * q, * t; If (p == NULL) {p = new node4x4; (इंट जे = 0; जे एंड एलटी; 4; जे ++) पी- & gt; डेटा [आई] [जे] = नंबर [आई] [जे]; // त्रुटि लाइन P- & gt; link = NULL; } और {q = p; जबकि (q- & gt; link! = NULL) q = q- & gt; लिंक; टी = नया नोड 4x4; (इंट जे = 0; जे एंड एलटी; 4; जे ++) टी-> डेटा [आई] [जे] = नंबर [आई] [जे] + // त्रुटि लाइन T- & gt; link = NULL; Q- & gt; link = t; }}

जब मैं संकलन करने की कोशिश करता हूं, तो मुझे यह कहते हुए एक त्रुटि मिलती है कि "त्रुटि C2109: सबस्क्रिप्ट को सरणी या सूचक प्रकार की आवश्यकता है" दिखाए गए अनुसार चिह्नित टिप्पणी की गई रेखाओं पर।

< P> क्या कोई कृपया मदद कर सकता है?

आपने 1-डी सरणी डबल टाइप करें लेकिन फ़ंक्शन में आप इसे 2-डी सरणी के रूप में उपयोग कर रहे हैं।

आपकी प्रत्येक लिंक सूची में डेटा नोड 2-डी सरणी की दोहरी है।

इसलिए आपके सभी सदस्य कार्यों को द्विआधारी के रूप में दो-डी सरणी को स्वीकार करना चाहिए।

बदलें: 

  शून्य अपेंड (डबल * संख्या); शून्य add_as_first (डबल * संख्या); शून्य ऐडफेर (इंट सी, डबल * अंक);

से 

  शून्य अपेंड (डबल संख्या [] [4]); शून्य add_as_first (दोहरे अंक [] [4]); शून्य ऐडफेर (इंट सी, डबल नंबर [] [4]);

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
