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 JavaScript … Read more
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 the … Read more
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 by … Read more
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 solved check if value inside the range [closed]

Can have public, protected, and private members. Can have virtual functions. And so on. If you find yourself wondering whether you should use a … Read more
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, much … Read more

It should be: [array[j], array[j + 1]] = [array[j + 1], array[j]]; instead of: [array[j], array[j + 1] = array[j + 1], array[j]]; Pay close attention to where the square brackets begin and end.
