int

问题 I am dynamically calling Windows API. I found some code online that can do this, and I took a whole lot of interest to it. The idea itself is brilliant to say the least. However, I can't seem to make it work for my code. The parameters for the dynamic call are as of type string , string int[] , and I would like to use the API GetThreadContext with the parameters of pInfo.hThred and ref ctx (shown below). API Call GetThreadContext(pInfo.hThread, ref ctx); The above code will make a call to the

问题 I am searching a lot but could not find exactly what i need till now. I have two integer arrayas int[] x and int[] y . I want to find simple linear correlation between these two integer arrays and it should return the result as double . In java do you know any library function providing this or any code snippet? 回答1: Correlation is quite easy to compute manually: http://en.wikipedia.org/wiki/Correlation_and_dependence public static double Correlation(int[] xs, int[] ys) { //TODO: check here

问题 I wrote a program to play hangman---it's not finished but it gives me an error for some reason... import turtle n=False y=True list=() print ("welcome to the hangman! you word is?") word=raw_input() len=len(word) for x in range(70): print print "_ "*len while n==False: while y==True: print "insert a letter:" p=raw_input() leenghthp=len(p) if leengthp!=1: print "you didnt give me a letter!!!" else: y=False for x in range(len): #if wo print "done" error: leenghthp=len(p) TypeError: 'int' object

问题 I'd like to know how can I convert a String in an Int array in Swift. In Java I've always done it like this: String myString = "123456789"; int[] myArray = new int[myString.lenght()]; for(int i=0;i<myArray.lenght;i++){ myArray[i] = Integer.parseInt(myString.charAt(i)); } Thanks everyone for helping! 回答1: let str = "123456789" let intArray = map(str) { String($0).toInt() ?? 0 } map() iterates Character s in str String($0) converts Character to String .toInt() converts String to Int . If failed

问题 I have the following JS immbedded in a page: var round = Math.round; var id = $(this).attr("id"); var len = id.length; var indexPos = len -1; // index of the number so that we can split this up and used it as a title var pasType = id.substring(0, indexPos); // adult, child or infant var ind = round(id.substring(indexPos)); // converts the string index to an integer var number = (id.substring(indexPos) + 1); // creates the number that will go in the title window.alert(number); id will be

问题 I tried looking up (int) but could only find documentation for the function int() in the PHP manual. Could someone explain to me what the above code does, and exactly how it works? 回答1: It convert (tries at least) whatever the value of the variable is to a integer. If there are any letter etc, in front it will convert to a 0. <?php $var = '1a'; echo $var; // 1a echo (int) $var; //1 $var2 = 'a2'; echo $var2; //a2 echo (int) $var2; // 0 ?> 回答2: You can find it in the manual in the section type

问题 I'm working on a game with monsters. Each one has a list of stats that are all going to be ints. I can set up each stat as it's own variable but I'd prefer to keep them in an NSDictionary since they are all related. I'm running into a problem when I'm trying to change the value's of each stat. What I Have: -(id) init { self = [super init]; if(self) { stats = [NSDictionary dictionaryWithObjectsAndKeys: @"Attack", 0, @"Defense", 0, @"Special Attack", 0, @"Special Defense", 0, @"HP", 0, nil]; }

问题 Got a problem with a code conversion from C# to VB.Net. var x = 5783615; var y = 56811584; var t = x * y; x, y and t are integers. In c# 't' will be -1553649728. In VB.Net, I will get an integer overflow exception. Any idea how to fix it? 回答1: C#, by default, doesn't check for overflows, but VB does (by default). You can setup your VB Project to not check for integer overflows in the Advanced Compile Options in the Compile tab. This will cause that specific project to stop raising

问题 A select field on my HTML form may yield 1 to 5 (integers). Using is_int rejects it every time, because the $_POST['rating'] is viewed as a string. After consulting the PHP Manual, it seems is_numeric() && !is_float() is the proper way to validate for an integer in this case. But I want to be certain, so please confirm or fire away at my logic. 回答1: I would use is_numeric() , because user input always comes in as a string (as far as I know). Another way to guarantee something is an integer is
