WebThe pseudo-random number generator is initialized using the argument passed as seed. For every different seed value used in a call to srand, the pseudo-random number generator can be expected to generate a different succession of results in the subsequent calls to rand. Two different initializations with the same seed will generate the same … Web可以利用 srand((unsigned int)(time(NULL)) 的方法，产生不同的随机数种子，因为每一次运行程序的时间是不同的。 4.产生随机数的用法. 1) 给srand()提供一个种子，它是一个unsigned int类型； 2) 调用rand()，它会根据提供给srand()的种子值返回一个随机数(在0到RAND_MAX之间)；
