Rand ()Returns a random value ranging from 0 to RAND_MAX. Before calling this function to generate a random number, you must use srand () to set the random number seed. If no random number seed is set, rand () will automatically set the random

The random number of a computer is generated by a pseudo-random number, which is a sequence of small m-polynomial, in which each small sequence has an initial value, that is, a random seed. (Note: The period of the small m polynomial sequence is 6553
