srand time 0

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:

Http://hi.baidu.com/jkxtu1984/blog/item/d5d1f1c6e5ac461d9d163dec.html The standard library (included in ) provides two functions to help generate pseudo-random numbers: Function 1: int rand (void );Returns a random integer between [seed, rand_max (0

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

Rand ()Returns a random value ranging from 0 to RAND_MAX. Before calling this function to generate a random number, you must use srand () to set the random number seed. If no random number seed is set, rand () will automatically set the random

Standard library (included in ) provides two functions to help generate pseudo-random numbers:function one: int rand (void);Returns a random integer between [seed, Rand_max (0X7FFF)), starting with the seed specified in Srand (seed).function two:

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

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

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
