i know there 2 types of functions: void , ones return (int, double, etc). if function declared without return statements? considered void function? example, myfunction(int value){ ....... } a function declared without return type considered returning int . ancient rule going original k&r c, left in language backward compatibility. integer promotions , conversion of float arguments double s done functions without prior definition or forward declaration same reason - backward compatibility old code. it needless relying on these rules new development bad practice. 1 should declare return type explicitly, , forward-declare or define functions before calling them.

this question has answer here: what's difference between html width / height attribute , css width / height property on img element? 7 answers differences between assigning attribute, style, , class in div 3 answers what difference between height="50" vs style="height:50px" ? and height="50" vs style="height:50" ? i confused this. presentation-related attributes such height="50" original way specify presentation details of html elements. however, have since been deprecated in favour of css, via style , class , id attributes, give lot more flexibility original attributes (at least because css can extended without touching definition of html itself, of course because "cascading" part, multiple un...

i not entirely sure why, receiving data looks n�f����s� call rss feed formatted in xml. exports.search = function(req, res) { request.get('https://secret.co/usearch/'+req.params.id+'/?rss=1', function (error, response, body) { console.log(body); if (!error && response.statuscode == 200) { parsestring(body, function (err, result) { res.json(result); }); } }); }; just on particular url, wondering how can solve , proper xml? the url in question delivers content gzip encoded. adding option gzip : true request call fix problem: exports.search = function(req, res) { request({ method : 'get', url: 'https://kat.cr/usearch/scarface/?rss=1', gzip: true }, function(error, response, body) { console.log(body); if (!error && response.statuscode == 200) { parsestring(body, function (err, result) { res.json(re...

i have following code (sample code) works well. think if there other better way can write following code snippet more accurately less code. if(language == "english") { if(student_id == 0) { somefunction(); } else { if(getmarks(student_id) > 50 || subjectcount > 1 || projectcount > 0) { somefunction(); } } } also, please note if student_id 0 , getmarks(student_id) throws error (for more complex scenario, check out this ) what suggest case is: to write less nested if-else block one way inverting conditions and gives early return whenever possible to combine conditions same actions (in case being somefunction ) to exploit short circuit evaluation implemented in c# (also implemented in many other programming languages - noted martheen in comment). if(language != "english") return; //assuming nothing below if(student_id == 0 || getmarks(student_id) ...
