### C + + random number rand () and seed function Srand ()

In computer programming, a random number is often generated. But it's not that easy for a computer to produce a random number. The execution of a computer is carried out in code, so it is not possible to produce a number that really has a random meaning, like a draw or a dice. It is possible to generate a pseudo-random

### Example of batch random number of time seed in PHP

PHP functions Mt_rand () and Rand () will have a chance of repeating random numbers when they are generated in batches. Srand () and Mt_srand () are not explicitly invoked at the beginning of PHP4.1, and seeds are automatically generated at Mt_rand and Rand. Because, in batches of random, we use the explicit bar to generate seeds, we can avoid duplication. Why, then? Because the seeds are different. Why is
