java - missing return statement for a for loop to sort numbers from lowest to highest -


यह प्रश्न एक सटीक डुप्लिकेट है: < / P>

  • 4 जवाब 
  सार्वजनिक एंटी सॉर्टिंग (Int साइड 1, इंट साइड 2, इंट साइड 3) {int [] xx = {side1, side2, side3}; Int trace = 0; के लिए (int i = 0; i & lt; xx.length-1; i ++) {के लिए (int j = i + 1; j & lt; xx.length; j ++) {if (xx [i] & gt; xx [j] ) {Int save = xx [i]; Xx [i] = xx [j]; एक्सएक्स [जे] = बचाओ; } ट्रेस ++; }} के लिए (int i = 0; i & lt; xx.length; i ++) {int संख्या = xx [i]; वापसी संख्या; }} // अनुपलब्ध रिटर्न स्टेटमेंट

त्रिकोण कार्यक्रम के भाग के रूप में न्यूनतम से लेकर सबसे ज्यादा संख्याओं की एक विधि बनाते हुए और यह मुझे एक गुम रिटर्न स्टेटमेंट त्रुटि देता है मुझे नहीं पता कि मुझे क्या याद आ रही है कृपया मदद करे।

आपका अंतिम लूप वास्तव में समझ में नहीं आता 

  (Int i = 0; i & lt; xx.length; i ++) {इंट संख्या = xx [i]; वापसी संख्या; }

यह हमेशा xx [0] वापस करेगा। क्यों लूप के लिए बिल्कुल भी है?

आपको जो त्रुटि मिल रही है वह हो रही है क्योंकि कंपाइलर नहीं जानता है कि लूप के लिए लूप होगा दर्ज किया जाए, तो ऐसा लगता है कि लूप को छोड़ा जा सकता है, इस स्थिति में कोई भी return कथन नहीं होगा।

इसके बजाय आपके के लिए पाश, आप शायद मतलब

<पूर्व> वापसी xx;

लेकिन तब आपको विधि हस्ताक्षर को 

  सार्वजनिक int [] सॉर्टिंग (int side1, int side2, int side3) में बदलने की आवश्यकता है

c++ - How to load a bitmap from file into the samples buffer -

I am trying to add text to the bitmap obtained from the DirectShow filter. First of all I tried to use gdiplus, but that was not working so now I just call a net program that connects to bitmap. The problem is that I do not know how to reload the bitmap from a file into buffer samples in a direct save. Here is my code: Bitmap BMP (640, 480, 2560, 1379773, Newbuffer); // save clsid pngClsid; GetEncoderClsid (L "image / PNG", & amp; pngClsid); WCHAR * file = L "D: \\ temp \\ sample.bmp"; Bmp.Save (file, & amp; pngClsid, NULL); Std :: string command ("D: \\ yourcontrol \\ bitmapDraw.exe D: \\ temp \\ sample.bmp \" test text \ "D: \\ yourcontrol \\ out.bmp"); // Heripal system (command.c_str ()); // Load Bitmap BMP 2 (D: \\ Your Control \\ Out.bmp); How do I forward bitmap from file to sample? Media samples are a part of the agreement between filters on specific pin connections. You usually do not load media samples until y...

javascript - How to get MySQL query result returned using $.ajax -

I'm trying to update is a JavaScript, when you hover over an image, a devi Floats near your mouse, this information is stored in an .js file as an array, for example. text [0] = ["image 1", "data1"] text [1] = ["image2", "data2"] In the past, if the array change / add / delete the data it will need to upload a new copy .js file, if the data was attached / deleted, then the new image needs a change in .dwt file Which can update each file using the .dwt file as the main template, which can result in 20+ pages They are uploaded I thought that I can automate this record by using the database and using the database if they are active and use only mysql queries which are active, such a black app The database can be added and disabled, thus eliminating the need for every soft upload of the file. To do this, I had planned to store the information in the database and create the above array based on the results, by researching how to us...
