I have a question about the arc4random() function in Objective-C.
In the examples I have seen online, there is a % symbol right after the function call. I think of % as the modulus operator, so does this symbol have another meaning when used after arc4random()? How does it work?
No special meaning. Applying a modulus after
arc4random()(or any other random function) is a common pattern to restrict the min/max of the random.arc4random() % 78will return you a number between 0 and 77, for example.
