 # `rand`
 
-Generates a pseudorandom number by using a well-known and fully-reproducible algorithm. A more programmatically secure version of this function is available; see [`rand_s`](rand-s.md). Numbers generated by **`rand`** are not cryptographically secure. For more cryptographically secure random number generation, use [`rand_s`](rand-s.md) or the functions declared in the C++ Standard Library in [`<random>`](../../standard-library/random.md).
