srand() is used to seed the built-in RNG algorithm. rand() returns a 'random' integer. This is a replica of an RNG, and demonstrates how seeding works. https://code.sololearn.com/cMUCJqFL1X65/?ref=app To some point, true randomness cannot really exist. You can only produce a number which is difficult enough to predict, without a constant pattern.
