But assuming you’ve settled your requirements, then you can use next example: if(input.matches(“[a-zA-Z]+(\\-[a-zA-Z]+)?”)) { //OK } else { //Invalid } Several examples I’ve tested using this page: String matches? qwe Yes qwe- No qwe-qwe Yes qwe-qwe- No qw2e-qwe2 No qwe-qwe-qwe No [ad_2] solved How … Read more
[ad_1] Let’s clean it up: var j = 0; var t = 0; do { j++; t += j; } while (j < 5); alert(t); If you manually expand this (and I will), this is the equivalent code without loops: var j = 0; var t = 0; j++; // j = 1 t += … Read more

[ad_1] Since JavaScript is a C-style language (syntactically derived from Java), all the known coding styles from those worlds are possible. Choose one yourself. If you’re working on a project with other people, you should agree on some coding conventions. Common and influential ones (from larger projects) are: Node.js style guide Crockford’s code conventions Google … Read more
[ad_1] As you can see from the declaration, argv is an array of char pointers. This means that your main function is not being passed the numerical value 5, but the (probably ASCII- or UTF8-) encoded string value “5”. If you look at ASCII table, you will see that the character “5” is encoded as … Read more
[ad_1] You want to use a data structure to store a sequence of objects. For example, an array could do this: Fruit banana[] = new Fruit[10]; for (int i = 0; i < 10; i++){ banana[i] = new Fruit(); } This creates 10 objects of type Fruit in the banana array, I can access them … Read more
[ad_1] This is a foolproof way of doing it although it is not the most efficient: from re import findall as f r=”5″ level=3 a = f(r'(\d+)?-?(\d+)’, r)[0] try: print int(a[0]) <= level <= int(a[1]) except (IndexError, ValueError): print 0 <= level <= int(a[1]) 3 [ad_2] solved check if value inside the range [closed]
[ad_1] Ok, I got bored and wanted to help (also, a question with that quantity of comments cannot be left without an answer :D), so took the Wikipedia PHP implementation and converted it to C#, but after a bit the user added he cannot use generics… So, I’m posting a full implementation, one with generics … Read more
[ad_1] This line … private readonly List<Department> departments = new List<Department>(); … should not be in the function, but outside, at the class scope, or make it a var. 4 [ad_2] solved Why does this code compile in one solution but not in another? [closed]
[ad_1] There are plenty of differences. A namespace is a grouping mechanism for names, nothing more or less. On the other hand, classes: Are types. Can be instantiated. Can be derived from. Can have public, protected, and private members. Can have virtual functions. And so on. If you find yourself wondering whether you should use … Read more
[ad_1] NSPredicate *predicate = [NSPredicate predicateWithFormat:@”wasRead = YES”]; NSArray *arr = [array filteredArrayUsingPredicate:predicate]; Can sort a thousand objects in 0.0004 seconds. Then just do: for (NSDictionary *object in arr) { //Statements } Edit: actually after further experimentation, using fast-enumeration is about four times faster, about 0.0001, which if scaled to 100000 objects can be much, … Read more
