Why would you use if-else statements if you can make another if statement? Example with multiple ifs: input = getInputFromUser() if input is "Hello" greet() if input is "Bye" sayGoodbye() if input is "Hey" sayHi() Example with else-if: input = getInputFromUser() if input is "Hello" greet() else if input is "Bye" ...
I have an if statement: if(authenticate_session("secret_password12345")){ alert("You are authenticated"); }else{ alert("Intruder alert!"); } and the javascript authenticate function, which makes an jQuery POST AJAX call to the server to do the actual authentication, and returns true or false: function authenticate_session(sess...
I am having a difficult time matching up curly brackets in this code. It keeps indicating a "else" without an "if" error but not sure how the syntax should read. If anyone can help it would be most appreciated. Here is the code: private void compileFactor() { boolean its_a_variable = theInfo.isVar(); if (isIdent(theToken...

I am just beginning Haskell, but from all the online tutorials I've found I can't seem to find if there is one accepted way to do a conditional control statement. I have seen if-else, guards, and pattern matching, but they all seem to accomplish the same thing. Is there one generally accepted/faster/more efficient way than the rest? ...
This is a sort of trivial question but something I've been wondering about. In terms of style (I assume the performance is identical), is it better to keep an 'else' in an if statement where it's not necessary? For example, which of the following is better: if (x < 10) doSomething(); else if (x > 20) doSomethingElse(); or if (...
I'm learning queues and I came across this piece of code. It's from a book, so I can't post the whole code here but what I'm posting will be sufficient. More than a problem, I just want to confirm that whether my understanding of this code is correct or not. In the function, delete_ap(), the 'if' statement calls qretrieve() function and...

They both return the same result in the end. Any reason one would be better to use than the ot...
