You should put the code inside the callback function, otherwise the nummer will just be 0. $(document).keydown(function(e) { switch (e.which) { case 38: $(“#object”).stop().animate({ top: “10” }); nummer = 0; break; case 40: $(“#object”).stop().animate({ top: “200” }); nummer = 100; break; } if (nummer == 100) { //do something it does have the protected class! … Read more
&& students[i].grupa = gr Blockquote in above code, = is an assignment operator you need == for a comparison operator 2 solved C++: Cannot compare double from an array of structures to another double in if function [closed]
Try this $time = strtotime(“now”); // You will get the current time in UNIX timestamp.. if(($time%2)==0){ header (‘Location: http://www.misitio1.com’); }else{ header (‘Location: http://www.misitio2.com’); } If you want to work on the value of the current hour or minute, $hr = date(“H”); //Change it depending on your wish, 12 hr or 24 hr time. This will … Read more
Here’s the answer, you should prompt for input, then check the input using a while loop instead of IF-ELSE to make sure the user provided the answer you desired. This is actually a simple logic question tho. You may explore do-while loop too. #include <iostream> using namespace std; int main() { string item; float price; … Read more
Let’s extract a method (ReadInteger) for it. Please, note, that we use int.TryParse instead of Convert.ToInt32 since user input is not necessary a valid integer private static int ReadInteger(String title = null) { if (!string.IsNullOrWhiteSpace(title)) Console.WriteLine(title); while (true) { if (int.TryParse(Console.ReadLine(), out int result)) return result; Console.WriteLine(“Sorry, the input is not a valid integer, try … Read more
I feel like taking risk to answer that but you can use Enumerable.All with char.IsDigit method and parse it to int like; if(myString.All(char.IsDigit)) { return int.Parse(myString); } Or better, use int.TryParse to check your string is valid integer or not. solved C# checking a whole char for numbers [closed]
I didn’t read your problem definition but your code sould be at least like this to be correct as syntax and logic: #include<stdio.h> float totalFee = 0; int hours = 0; int main(void) { int i; int b; printf(“Please Enter Number of Cars “); scanf(“%d”, &i); for (b = 0; b < i; b++) { … Read more
First off, note that if and else always apply to the single statement that follows them. You can use { } to group multiple statements into a single compound statement, but the conditional then applies to the single { … } statement. Consider these two equivalent statements: if (foo) { bar(); } if (foo) bar(); … Read more
Should be if ( score>==90 ) { document.write ( “Your grade is an A.” ) } else if ( score >==80 ) { document.write ( “Your grade is a B.” ) } else if ( score >==70 ) { document.write ( “Your grade is a C.”) } else if ( score >==60 ) { document.write … Read more
is this perhaps what you are trying to do?: if monthly_salary < 4000: deductions = 0.12 + 0.04 + 0.01 + 0.06 elif monthly_salary >= 4000 and monthly_salary < 8000: deductions = = 0.20 + 0.07 + 0.03 + 0.06 elif monthly_salary >= 8000 and monthly_salary < 16000: deductions = 0.30 + 0.09 + 0.05 … Read more
nextInt() consumes the entire token 013601267, not just a single digit, which was not your plan. A much easier approach could be to consume it as a single string and then iterate over the characters: String num = s.next(); int sum = 0; for (int i = 1; i <= num.length(); ++i) { sum += … Read more
Use == not = if (num == 1) { system(“start C:\\test\\vw”); Sleep(2000); } else if (num == 2) { system(“start C:\\test\\vw2”); Sleep(2300); } else if (num == 3) { system(“start C:\\test\\vw3”); Sleep(1800); } == is for comparison, = is for assignment The reason why it always chooses the first option is because C++ (and C) … Read more
This would be a lot simpler using a switch/case logic scheme. I have re-coded what you had up there using switch/case and this might be a good intro for you to learn switch/case. You had some extra ( ) in one of the if statements above. I hope this helps, friend: <? $unix_time = 6734; … Read more
Sending something to the browser with echo”Your Login Name or Password is invalid”; does not make any sense before calling header(“location: invalid.html”); because you can’t send header information after you send payload. You should remove the echo-Line or the redirect will not work. In addition to that, session_register() is deprecated by PHP 5.3 and got … Read more
Loop for( statement expression; action ) body loop is just a while loop { statement; while ( expression ) { body label_for_continue: action; } } So you can see that everything declared inside will have its life ending outside of for. You can use break to stop loop prematurely and continue to jump back to … Read more
