srand
srand expr
Sets the random number seed for the rand operator so that rand can produce a different sequence
each time you run your program. If expr
is omitted, a default seed is used that is a mix of
difficult-to-predict, system-dependent values. If you call
rand and haven’t called
srand, rand calls srand with the default seed.
