conditional-statements

If I have an If statement with 2 conditions - and the first fails, will the 2nd condition even be considered or will it go straight to the else ? So, in the following example, if myList.Count == 0 , will myString be compared against "value" or will it just straight to else ? if(myList.Count > 0 && myString.Equals("value")) { //Do something } else { //Do something else } Paul Spangle It will stop evaluating because you're using the double ampersand && operator. This is called short-circuiting . If you changed it to a single ampersand: if(myList.Count > 0 & myString.Equals("value")) it would

I need a particular script to be triggered in Internet Explorer browsers Only! I've tried this: <!--[if IE]> <script></script> <![endif]--> Unfortunately this actually stops the script from being loaded. EDIT: For everyone asking why I need this: IE makes scrolling extremely jumpy when using some animations. In order to address this I need to implement a script that provides smooth scrolling to IE. I don't want to apply it to other browsers as they don't need it and this script although making the scrolling smoother also makes it a bit unnatural. I'm curious why you specifically need to target

When I tried the following code I get the error mentioned. if(a==1) int b =10; But the following is syntactically correct if(a==1) { int b = 10; } Why is this? sheu This is actually a fairly interesting question. It's not as simple as it looks at first. For reference, I'm going to be basing this off of the latest C11 language grammar defined in N1570 I guess the counter-intuitive part of the question is: if this is correct C: if (a == 1) { int b = 10; } then why is this not also correct C? if (a == 1) int b = 10; I mean, a one-line conditional if statement should be fine either with or without

Are elseif and else if completely synonymous, or is there a difference? Does Zend have an accepted "standard" on which one to use? While I personally dislike seeing elseif in the code, I just need to know if they're synonymous and the PHP manual isn't the easiest to search. From the PHP manual : In PHP, you can also write 'else if' (in two words) and the behavior would be identical to the one of 'elseif' (in a single word). The syntactic meaning is slightly different (if you're familiar with C, this is the same behavior) but the bottom line is that both would result in exactly the same

Just wondering if anyone has come across this before. I found in a project (that was handed over from another developer) a conditional statement that looked something like this: if (variableOne == true | variable2 == true) { // Do something here } It didn't error, so seems to work. But, myself and a colleague have never seen an OR statement with a single pipe | , only 2 || . Can anyone shed light on this mystery? Thanks, James This is a bitwise OR operator. It will first convert it into a 32 bit integer, then apply the bitwise OR operation to the two numbers that result. In this instance,

I have a database with companies and their products, I want for each company to have a separate product id sequence. I know that postgresql can't do this, the only way is to have a separate sequence for each company but this is cumbersome. I thought about a solution to have a separate table to hold the sequences CREATE TABLE "sequence" ( "table" character varying(25), company_id integer DEFAULT 0, "value" integer ) "table" will be holt the table name for the sequence, such as products, categories etc. and value will hold the actual sequence data that will be used for product_id on inserts I

I have an IBOutlet that I have linked to from the storyboard @IBOutlet var creeLigueBouton: UIBarButtonItem! and I want to make it disappear if a condition is true if(condition == true) { // Make it disappear } Do you really want to hide/show creeLigueBouton ? It is instead much easier to enable/disable your UIBarButtonItems. You would do this with a few lines: if(condition == true) { creeLigueBouton.enabled = false } else { creeLigueBouton.enabled = true } This code can even be rewritten in a shorter way: creeLigueBouton.enabled = !creeLigueBouton.enabled Let's see it in a UIViewController

In C or C++ if ( x ) statement1; else statement2; For what value of x will both statements be executed? I know we can execute if-else together like this: if(1){ goto ELSE; } else{ ELSE: } Is there any way, like a value? (Which I think is not possible. Asking because someone is arguing!) for what value of x both statements will be executed? There is no such value: either the value evaluates to true (something != 0), or it evaluates to false ) (0). No other possible values exist. I know we can execute if-else together like this: if(1){ goto ELSE; } else{ ELSE: } That works but it isn’t depending

I'm creating a console app and using a switch statement to create a simple menu system. User input is in the form of a single character that displays on-screen as a capital letter. However, I do want the program to accept both lower- and upper-case characters. I understand that switch statements are used to compare against constants, but is it possible to do something like the following? switch(menuChoice) { case ('q' || 'Q'): //Some code break; case ('s' || 'S'): //More code break; default: break; } If this isn't possible, is there a workaround? I really don't want to repeat code. This way:
