srand time null

It can be considered that rand () is viewed every time it is called:1) If you have previously called srand (SEED) and specified a value for seed, it will automatically callSrand (SEED) is used once to initialize its starting value.2) If you have not

The Srand function is the initialization function of the random number generator. Prototype: void Srand (unsigned seed); Usage: It initializes a random seed that provides a seed that corresponds to a random number, and if the rand () function

Srand (unsigned) time (NULL) and use and understanding of rand () functions, srandrand 1. First, let's talk about the rand () function.   The rand () function is equivalent to a random number generator. The generated number ranges from 0 to 32767

See Summer snow on the winter of Rand () and srand () produce random number of summary, very good, study, and then have Baidu other people's results, the system summarizes. This article turns from Summer snow winter:

In some productsSource codeSuch a statement is often found, Srand (unsigned (Time (null ))); Why is this actually quite simple. 1. The time () function indicates the number of seconds from 00:00:00 to the current time. The time (null) function

This is a two function!Srand functionOne is the Srand function! This is used before calling the rand () function! Rand () is a function that produces a random number! And Srand is a function that sets the seed of a random number! Usually these two

Srand () is to provide seed for rand (). If srand inputs the same value each time, the random number generated each time is the same, Srand (N) For (10) Rand ()That is to say, using a fixed value as the seed is a disadvantage. The common practice is

use of the Random function rand () and Srand () in C + +First, Rand ()Name of function: RandFunction: Random number generatorUsage: int rand (void);Header file: stdlib.hFunction Description:The internal implementation of RAND () is made with linear

Http://www.cnblogs.com/lenient/articles/1565376.html First we have a general view of Rand&srand: Srand initializes random seeds, Rand produces random numbers, which are described in detail below. RAND (generating random numbers) Table header file:

Using some computer intelligent algorithms (GA, PSO, Ann etc .) during simulation, you often need to randomly generate the initial population (initial sample) to see Generate pseudo-random numbers for these two functions ~~~1. Generate a real
