Can I set a range of numbers when using arc4random()? For example 50-100 only.
As pointed out in other posts below, it is better to use
arc4random_uniform. (When this answer was originally written,arc4random_uniformwas not available). Besides avoiding the modulo bias ofarc4random() % x, it also avoids a seeding problem witharc4randomwhen used recursively in short timeframes.will generate 0, 1, 2 or 3. Thus you could use:
and merely add 50 to the result to get a range between 50 & 100 (inclusive).
