Let us break it down. isset($_SESSION[‘id’]) == 1 The first part, the isset() call, will return a boolean value (true or false), depending on if the session id is set or not. When you compare an integer value with a boolean value, using the == operator, the integer will be coerced (or cast/type-juggled) into a … Read more
<?php echo (empty($LOGO) ? $TITLE : $LOGO) ?> will show $TITLE if $LOGO is empty. Otherwise will only show $LOGO. This operator is called the ternary operator. empty works like this: The following things are considered to be empty: – “” (an empty string) – 0 (0 as an integer) – 0.0 (0 as a … Read more
def input_guess(guess): …. if guess_num == real_num: print ‘Congratulations, blablabla!’ new_game() else: print ‘You guessed: ‘, guess_num,’.’, print ‘You have’, remainding_guess_times, ‘guesses left.’, if guess_num > real_num: print ‘blablabla’ else: print ‘blablabla’ solved Python – print in an if,elif, else statement
you are using arithmetic operations on strings. that for sure makes no sense create a float from the textfield input if ([_label3.text floatValue] >= 20.0) {_label4.text = @”0″;} aslo you have to change the 1st and 2nd else branch, a the last one will never be called, as if it is true, the fist one … Read more
Following updated question, here is another try … if ((entity.Price != 100000 && entity.Area != 2000 && entity.Number != 55) || (entity.Type != 3 || entity.Fraction <= 0.3)) { // Do stuff } Of course if you break those three statements out in to separate Boolean values that are appraised first then it is more … Read more
NULL results in a false condition. You could imagine that NULL is a 0, so this: if(NULL) would be equivalent to this: if(0) thus your code would become: #include <stdio.h> #include <iostream> int main() { if(0) std::cout<<“hello”; else std::cout<<“world”; return 0; } where is obvious that because 0 results to false, the if condition is … Read more
Or you can put your if statements between quotes: ex: if choice == “1” print(“nr 1”) elif choice == “2” so on .. solved Simple elif statement
Its variable type mistake. Check your assigned variable, you assigned the Array Element not the entire array. so try like below. <?php $result = mysql_query(“SELECT * FROM hr_recruitment_stages where vacancy_ref=”$vacancyref” order by added_on DESC limit 0,1″) or die(‘ERROR 315’ ); $row = mysql_fetch_array($result); $stage_name = $row[‘stage_name’]; if($stage_name == ‘Shortlisting’) { echo”Shortlisting”; } else { echo”Not … Read more
may be case is not matchingyou can try 1) if (newString.matches(aVar)){ } or 2) if (newString.equalsIgnoreCase(aVar)){ } or try with newString.trim() then compare trim() method removes spaces after and before the variable like if String s=”abc “; //space at last s.trim() will remove last space and return “abc” 3 solved Java equals function not working … Read more
A couple of comments regarding your code. You should mark your fields as private and then access to them trough getter/setter. class RF { private final String nom; private final String ref; private final String num; I don’t know why they are final (I don’t hink they should) anyway. Then RF n = (RF) jComboBox1.getSelectedItem(); … Read more
Based on what you’ve shown: testNum is greater than scores.length. This means that when you traverse the array by comparing your iterator (i) to testNum rather than its actual length, you will hit indexes which don’t exist. For example, let’s say testNum = 8 and scores.length = 5. Then in your code, you will get … Read more
No it will not execute the else statement if the if condition is satisfied 0 solved Will my program execute “else” even if it executed my “if”?
ngFileUpload error event callback receives 4 arguments as in: https://github.com/danialfarid/ng-file-upload/blob/master/dist/ng-file-upload-all.js#L509-514 promise.error = function (fn) { promise.then(null, function (response) { fn(response.data, response.status, response.headers, config); }); return promise; }; headers is the 3rd argument, config is the 4th argument. In your code config is referencing headers. headers.file is undefined so this is how you get the error … Read more
This line almost always return 0 and that is why it does not get into the while. var randomNumber = Math.floor(Math.random()); Math.random() return float values lower than 1 starting from 0 … and with Math.floor you are getting the int part which indeed is 0 1 solved Why does Math.floor(Math.random()) function always return “0”?
Use this instead: status_label.Text = err.InnerException == null ? err.Message : err.Message + ” || ” + err.InnerException.Message; 5 solved Streamlining If statement c# [closed]
