Random General

There is not a class in Objective-C with a method for generating random numbers but C may be used.  E.g: rand(), srand(), random(), srandom() and arc4random().

arc4random() tends to be preferred as it does not require seeding (it automatically initializes itself).

Examples:

	int RandomNumber = arc4random() % 3;	//Get random number from 0 - 2 (yes 2, not 3)

	int RandomNumber =  ((arc4random() % 901) + 100);	// Get random number between 100 and 1000
