How to Programming with If-statement

c#,if-statement,alphanumeric

From what I can tell, your code works fine. This little test script I ran: <?php echo test_title( '' ); echo test_title( 'pdf' ); echo test_title( 'This one works' ); function test_title( $title ) { echo "testing '$title'. "; if( empty( $title ) || mb_strlen( $title, 'UTF-8') <= 3 ){...

PHP - If a string or variable begins with a vowel

$vocals = array('a','e','i','o','u'); if (ctype_alpha($original) && in_array($original{0}, $vocals)) { print "oké"; } else { print "pas oké"; } With $string{index} you could access to a char into a certain position into $string. With in_array you could check if that letter is contained into an array (in our example, vocals array)...

how does Java handle && inside if statement

sql,regex,oracle,validation,if-statement

The condition is evaluated from left to right, which means intArray[j] < intArray[j - 1] is evaluated first. Therefore if j<=0, you'll get an exception. Changing the order to while (j > 0 && intArray[j] < intArray[j - 1]) { will prevent the exception (assuming the initial value of j...

Oracle regular expression REGEXP_LIKE for multiple columns

Since they all need to match the same Regex pattern, to be alphanumeric, you can validate on the concatenation of these 3 values: IF REGEXP_LIKE(i.TAX || i.NAME || VarTelephone , '^[A-Za-z0-9]+$') However this does not behave exactly as your question condition, since if just one or two of the values...

The if statement doesn't work for false in php

Python Reuse a Variable in the Else Block of an If-Else Statement

When you call getSrc a second time, the value of source that was created the first time has long since gone out of scope and been garbage collected. To prevent this, try making source an attribute of the function the same way you did for has_been_called. def getSrc(): if getSrc.has_been_called...

Swift won't allow me to use `!=`

ios,swift,if-statement,null

doubleValue can not be nil. A double value of NSString is a simple type (double) and can not have nil as value, so the compiler can not compare them. You can check if your NSString is nil or if the doubleValue is 0.

swift,if-statement,random

In Swift you cannot read a value before it's set, which you're doing here: if Int(randomNum) == guessInt If you change your declaration from this: var guessInt:Int to this: var guessInt = 6 then your code will work as expected (assuming you want the user's guess to be 6)....

Preventing the user from entering identical elements(within a malfunctioning try catch)

java,if-statement,arraylist,try-catch

So, when Inp=sc.nextInt(); fails because the user enters an invalid number, then an InputMismatchException gets thrown. Then you loop again, and eventually attempt to run Inp=sc.nextInt(); again. The problem though is that the invalid number that was entered is still in the input stream waiting to be read. So in...

How do I format the logic for 3 conditions and use a previous condition as well?

The second condition should be changed, otherwise the third if won't be reached. Also the third condition should be changed to check if the daysLate variable is greater or equal to zero: if (daysLate > 90) { costDue = bookPrice + 10; } else if (daysLate >= 7) { costDue...

considering if, else if, else statements when writing code (java)

javascript,jquery,if-statement,click,int

In practice, for only three elements, the Math.max/Math.min solution is probably best. However, when you find yourself labeling variables with numbers like n1, n2, and n3 you should at least consider using an array. The array n in the following has index values 0 through n.length-1, that is, 0, 1,...

Jquery, Javascript click && value

You're thinking about click wrong. It means "When the button is clicked". It isn't a condition that you are testing for at the time the code runs. It is setting up an event handler to run later. So you need to rethink your test: if a button is clicked and...

Rails Devise Routes: If user signed in, point to index. Else, point to new user session

ruby-on-rails,ruby,if-statement,devise,routes

Getting my program to go back to the “top” (if statement) (Java)

java,if-statement,while-loop,leap-year

You're on the right track with a while statement. It's pretty simple to keep it from executing infinitely. As soon as the user enters a correct year, the loop condition will evaluate to false and exit. System.out.println("Enter a year after 1750:"); leapYear = in.nextInt(); while(leapYear < 1750){ System.out.println("You have entered...

How to make nested IF statements neater

javascript,html,css,if-statement

Sure, here it is: if len(abc) > x and abc[x] == 'fish': dostuff else: dootherstuff and short-circuits, so abc[x] == 'fish' will only be evaluated if len(abc) > x is True. Most languages have a similar operator (e.g. && in C). & is for bitwise "and," and doesn't short-circuit, so...

How do I get my logic in this Java program to make my loop work?

Time complexity of if-else statements in a for loop

php else statement not working (closed)

The reason your else is never invoked is becuase your if clause is always true. if($page == 'Province' || 'Provinsi') The reason this always evaluates to true is because 'Provinsi' by itself is a value that does not evaluate to 0, NULL, or false. If it doesn't evaluate to 0,...

This is a problem of scope. Your code: if (!fileOpenTest) { Excel.Workbook templateBook = excelApp.Workbooks.Open(templatePath); } else { Excel.Workbook templateBook = excelApp.Workbooks[templatePath]; } declares the templateBook variable inside the blocks and thus its scope is limited to within that block.
