Kirat[ad_1] Here’s a possible solution: Use the same name, just at different scopes. #include <iostream> #define LOG(x) do { log() << (x) << ‘\n’; } while(false) std::ostream & log() { return std::clog; } struct Identifier { std::ostream & log() { return ::log() << id << “: “; } int id; explicit Identifier(int n) : id(n) … Read more
[ad_1] A summary of options suggested in the comments (and some others): dd<-data.frame( A= 1:3, B= 2:4 ) You can get the sum of the columns with dd$A + dd$B rowSums(dd) with(dd, A + B) dd[,1]+ dd[,2] dd[,”A”]+ dd[,”B”] apply(dd, 1, sum) do.call(‘+’, dd) Reduce(“+”,dd) [ad_2] solved adding each element each row of two columns … Read more
[ad_1] Its pretty sure for security reasons this isn’t possible in any browser. Otherwise links to phishing sites will become much, much harder to detect, because attackers can then just place a genuine URL in the status bar while the dangerous link actually leads elsewhere You can refer to this stackoverflow link for more details … Read more
[ad_1] The posted code is just fine it calls the URL http://localhost:8080/HTTP_Connection/index.php with the parameter firstKey and its value firstValue Unless you forgot to do the imports which would result in a compile error to begin with. I guess your error is on the server side. Please double check the server. For sure your question … Read more
[ad_1] JSON is not HTML. You cannot have a <head> element in a JSON file. It makes the JSON invalid, so it cannot be parsed. [ad_2] solved Ask about server send json and client receiver for process [php] not work when server have tag ?
[ad_1] If I’m understanding this, you want to filter out words that are the same if u turn them around like: lol, radar, rotator? I’d say make a method like this: -(BOOL) isSymmetrical(NSString*) string { int maxLength = round([string length] / 2 + 1); int frontCharNum = 0; int lastCharNum = [string length] – 1; … Read more
[ad_1] You need an array, you can’t do it like that: int i = 2; // get the input from somewhere var values = new string[i]; But that doesn’t mean it’s not possible.You can even create dynamic assemblies,classes,properties,if you really want to.See this documentation for more details: Emitting Dynamic Methods and Assemblies [ad_2] solved Dynamically … Read more
[ad_1] My guess is that you should be using $(this).data(), not $(‘div’).data(), so that each DIV will keep track of its own animation state. $(‘div’).click(function () { var data = $(this).data(‘animate’); if ( data == 10 ) { $(this).animate({ height: 100 }, 200); $(this).data(“animate”,”100″); } else if ( data == 100 ) { $(this).animate({ height: … Read more
[ad_1] You use of strtok() is wrong: line = strtok(buffer, NULL); should be line = strtok(NULL, delim); Another mistakes should be fixed similarly. The elements of text_lines are uninitialized: text_lines = malloc(6000 * sizeof(char*)); this allocated 6000 pointers to char, but none of these pointers are initialized. 0 [ad_2] solved where is the pthread segfault … Read more
[ad_1] Yes, you can develop without Visual Sturio. You could use csc or msbuild at the command line, you could use any of a range of alternative IDEs, or you could use Visual Studio Express, which is free. The .NET framework is freely available to Windows users. Alternatively if “free” and “free” isn’t good enough: … Read more
[ad_1] You can use HttpServerUtility.UrlDecode() Server.UrlDecode(Request.QueryString[“title”]).Replace(“_”, ” “); 3 [ad_2] solved Display query string asp.net
[ad_1] What you’re looking for is an else statement. I’d recommend you to do a basic python tutorial before starting to ask questions here. dice = int(dice) if dice in {4, 6, 12}: print(“…” + str(dice)) else: print(“error message”) 13 [ad_2] solved Send the user an error message when they input anything apart from 4, … Read more

[ad_1] You can check every input by using each on all input fields $(form).find(‘input’).each(function(index, elem){ if($(elem).val().length == 0){ //this field is empty } }); [ad_2] solved how to check serialize data is empty on submit button’s click
[ad_1] As told in the comments, you can see how to check if a number is an integer or not, and perform an appropriate action: Checking if float is an integer. However, if you want more interesting way, without any conditions: float a; float result; cin >> a; result = std::floor(a) – !std::ceil(a – std::floor(a)); … Read more
