srand. The 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.

The srand() function initializes the rand() function with a seed. The seed specifies which sequence of numbers the rand() function will follow. This means that the same seed will always result in the same sequence of random numbers. The srand() function is defined in the <stdlib.h> header file.
5 dni temu · The std::rand() in C++ is a built-in function that is used to generate a series of random numbers. It will generate random numbers in the range [0, RAND_MAX) where RAND_MAX is a constant whose default value may vary but is granted to be at least 32767.
The srand () function sets the seed for the rand () function. The seed for rand () function is 1 by default. It means that if no srand () is called before rand (), the rand () function behaves as if it was seeded with srand (1).
Funkcja ustawia punkt startowy, który jest stosowany do generowania serii pseudo losowych liczb całkowitych. W celu reinicjalizowania generatora, ustaw wartość 1 dla argumentu seed. Każda inna wartość przekazana jako seed ustawia losowy punkt startowy generatora.
21 paź 2015 · The srand function uses the argument as a seed for a new sequence of pseudo-random numbers to be returned by subsequent calls to rand. If srand is then called with the same seed value, the sequence of pseudo-random numbers shall be repeated. ...
12 paź 2023 · Funkcja srand ustawia punkt początkowy generowania serii liczb całkowitych pseudorandom w bieżącym wątku. Aby ponownie zainicjować generator w celu utworzenia tej samej sekwencji wyników, wywołaj srand funkcję i ponownie użyj tego samego seed argumentu.
