C++ inherites the numeric functions from C and has a random number library.
Random numbers are necessary for many domains, e.g., to test software, to generate cryptographic keys or for computer games. The random number facility of C++ consists of two components. There is the generation of the random numbers, and there is the distribution of these random numbers. Both components need the header
Random number generator
The random number generator generates a random number stream between a minimum and maximum value. This stream is initialized by a “so-called” seed, guaranteeing different sequences of random numbers.
