Webb24 juni 2024 · srand () seeds the pseudo-random number generator used by rand () . If rand () is used before any calls to srand (), rand () behaves as if it was seeded with srand(1) . Each time rand () is seeded with srand (), it must produce the same sequence of values. rand () is not guaranteed to be thread-safe. Parameters (none) Return value WebbThe seed () method is used to initialize the random number generator. The random number generator needs a number to start with (a seed value), to be able to generate a random number. By default the random number generator uses the current system time. Use the seed () method to customize the start number of the random number generator.
