You are expecting the cast from int to unsigned int to simply change the sign of a negative value while maintaining its magnitude. But that isn’t how it works in C or C++. when it comes to overflow, unsigned integers follow modular arithmetic, meaning that assigning or initializing from negatives values such as -1 or … Read more
Use google. In C++ you must define a type of variable. Look for a C++ tutorial, there are many of them. Use google. 1 solved C++ code is wrong
Keep the variable a outside loop. def deviser(n): a=[]; i=1; while( i<= n): x=n%i; if( x == 0 ): p = a.insert(0, i); print i; i = i+1; return a; >>> deviser(18) 1 2 3 6 9 18 [18, 9, 6, 3, 2, 1] >>> solved How can i make self updating list in python?
I’m not sure what is your question, but as @crashmstr commented .. it seems you don’t need an Enum but you just need a class to hold these properties Any way you can use this BUT IT’S NOT A GOOD PRACTICE and I don’t know what do you want the setter to do public string … Read more
The use of parent.Bottom is indicative that an iframe named “Bottom” exists within the page. Based on that, you can assume that the method changeDiv() is setting this iframe’s content to Intro.asp, and that proceed() is submitting a form called frmChange within that iframe. I would also add that the MM_ methods are not directly … Read more
I need to get process name from process id in windows to find process names associated with a logged event. If you are getting the Process ID from a log, it will only be valid if the original process is still running. Otherwise, the ID is no longer valid for that process name. If the … Read more
Solution (w is the responseWriter) str := “{\”key1\”:{\”key2\”:\”value1\”,\”key3\”:\”value2\”}}” w.Write([]byte(str)) 2 solved Encode arbitrary string to JSON in http response
It is completely up to the implementation. For example, const data on bare metal ARM uCs is stored in the FLASH memory. You can write to there but it will have no effect at all. Hosted systems will behave differently depending on the OS, its version and hardware. How can I overwrite a const block … Read more
Here you go: <?php $array = array( array(1,2), array(3,4), array(5,6), array(7,8) ); function processArray(&$array) { for ($i = 0; $i < count($array); $i++) { if ($array[$i][0] > 4) { $array[$i][0] = $array[$i][0] – 3; } if ($array[$i][1] < 5) { $array[$i][1] = $array[$i][1] + 3; } } } processArray($array); print_r($array); Outputs: Array ( [0] => … Read more
You have to count only owners id with DISTINCT word, which counts only unique owners. SELECT owners.city, count(DISTINCT owners.id) AS ‘Owners’ FROM owners INNER JOIN dogs ON (owners.id = dogs.owner_id) GROUP BY owners.city 1 solved Mysql Query [0001]
I ran your code through the NAG Fortran Compiler (on Linux). The version you have posted doesn’t compile for me: > nagfor -mtrace=all -u -C=all -C=undefined valuefuncmat.f90 … Error: valuefuncmat.f90, line 100: Syntax error detected at )@, … That of course is easy to rectify (i.e., change line 100 to write(*,'(20G12.4)’) vOUT(i,:)).

Use Time::Piece. It’s a standard part of the Perl distribution. Use strptime (string parse time) to parse your string into a Time::Piece object. Then use strftime (string format time) to display your Time::Piece object in whatever format you want. #!/usr/bin/perl use strict; use warnings; use 5.010; use Time::Piece; my $in_format=”%Y-%m-%d %H:%M:%S”; my $out_format=”%Y-%m-%dT%H:%M:%SZ”; my $in_date=”2015-08-18 … Read more
int a[5] a is an array of 5 int. int (*a)[5] a is a pointer to an array of 5 int. int a[5][4] a is an array of 5 array of 4 int. int *a[5] a is an array of 5 int pointers. 6 solved What’s the difference between “int a[5]” and int (*a)[5], int … Read more
You can use an extension method like this public static class StringExtensions { private static char[] _alphabet; static StringExtensions() { _alphabet = “abcdefghijklmnopqrstuvwxyz”.ToCharArray(); } public static bool ContainsAlphabet(this string input) { return !_alphabet .Except(new HashSet<char>(input)) .Any(); } } “asdasd”.ContainsAlphabet(); //false “abcdeffffghijklmnopqrstuvwxyzzz”.ContainsAlphabet(); //true 0 solved Check if the string contains all the characters from a to … Read more
