Also there are other (much simpler) PRNG engines defined in C++11 standard -std::linear_congruential_engine<>(historically used as fair qualitysrand/randalgorithm in some C standard library implementations) andstd::subtract_with_carry_engine<>. They also generate fully defined parameter-dependent pe...
Random意思是返回一个0~num-1之间的随机数。 random(num)是在stdlib.h中的一个宏定义。num和函数返回值都是整型数。如需要在一个random()序列上生成真正意义的随机数，在执行其子序列时使用randomSeed()函数预设一个绝对的随机输入，例如在一个断开引脚上的analogRead()函数的返回值。
private int randomnumber(int min, int max) { Random rnum = new Random(); return rnum.Next(min, max); } Use the above function in a location where you want to use random numbers. Suppose you want to use it in a text box.
As C does not have an inbuilt function for generating a number in the range, but it does have rand function which generate a random number from 0 to RAND_MAX. With the help of rand () a number in range can be generated asnum = (rand() % (upper – lower + 1)) + lower // C...

srand(int)用来设种子,然后每次rand()返回一个随机值 种子最好是每次都不同的，否则你每次得到的都是同样的一系列伪随机数，通常让种子和当前时间相关，比如 srand((unsigned)time(0));
