1) arc4random () is more accurate and does not need to be generated immediately. Usage: The code for getting an integer between 0 and X-1 through arc4random () is as follows: Int value = arc4random () % x; The code for getting an integer between 1 and X is as follows: Int value = (arc4random () % x) + 1; 2). It is used in ccrandom_0_1 () cocos2d and the range is [0, 1]. Usage: Float random = ccrandom_0_1 () * 5; // [] ccrandom_0_1 () value range: []

Replacing multiple URLs in an article with a random number requires that the random numbers following each URL be different. There are many articles in the database. There are many URLs in this article. I want to add random numbers to the URLs, but the random numbers behind each URL are different. I wrote a replacement

Cocos2d-x on the problem of random number acquisition, cocos2d-x Random Number We used to get a random number when playing a game. 1 rand()%(end-start+1)+start; The end and start parameters are used to set the random number range. To obtain a random number that is close to

Use -- random number usage and probability of generation, random number Probability The Random class is used to generate Random numbers within a specified range. The constructor has two types of constructor without parameters and parameters. The constructor with parameters has the number of seeds. Assume that the fol

Random numbers in Linux can be generated from two special files, one/dev/urandom. The other is/dev/random. The principle of generating random numbers is to use the current system's entropy pool to calculate a fixed number of random bits, and then return these bits as a byte stream. Entropy pool is the current system of

In connection with the introduction of discrete random variables, after defining the expected e[x of the random variable x], we tend to focus on the random variable e[g (x) of the function of x in the actual problem, and continue to discuss the expectation of the discrete random variable function, we can easily make th
