The rand_s function writes a pseudorandom integer in the range 0 to UINT_MAX to the input pointer. The rand_s function uses the operating system to generate cryptographically secure random numbers. It does not use the seed generated by the srand rand.

Nonostante tutte le persone suggeriscono rand() qui, non si vuole usare rand() meno che non sia necessario! I numeri casuali che produce rand() sono spesso molto cattivi. Per citare dalla pagina man di Linux: Le versioni di rand() e srand() nella libreria C di Linux utilizzano lo stesso generatore di numeri casuali di random(3) e srandom(3), quindi i bit di ordine inferiore dovrebbero essere

Random Number Generation
In C++ (and C), the functions needed from cstdlib are rand() and srand() srand() is used to seed the random number generator (and only needs to be called once). The seed value could be obtained from user input, but usually the best way is to use the time value obtained from the computer’s clock, since that will change frequently (like between runs of the program)
