generate 1000 random card deck shuffles at once c++

I'm basically trying to build a computer simulation of a casino game idea that uses a standard deck of 52 cards.

I would like to run 1000 games at once.

I've used srand(time(NULL)) before, but I dont think it's possible to output 1000 different random number sequences at one time with this, is there? My perception is that since all the numbers are generated at the same time, that they will all be the same.

Is there a way to use the first generated random number to seed 1000 new 52 number sequences?

Thanks

Solution

  • Seeding with the same number will always lead to the same sequence of pseudo-random numbers. As long as you don't re-seed with the same seed in between iterations, the (sub)sequences are not going to be the same.
