if I generate numbers with the same seed always...... does I will obtein always the same numbers when executing my program?

If I generate numbers with the same seed, but run the program in different machine, does I will obtein the same numbers?

If I generate numbers with th same seed always, but make two programs with differents compilers..... does I will obtein different numbers from both programs when executed?

thx.

Sounds pretty "homeworky".

I suggest you learn how they work, and that way you can answer all of your own questions. Not to mention you'll learn something http://www.eternallyconfuzzled.com/t..._tut_rand.aspx

Yes.

>in different machine, does I will obtein the same numbers?
Perhaps. It depends on how you link to the random number generator. If it's dynamically linked and the different machine uses a different generator, you'll likely get a different sequence.

Probably not, unless both compilers use the same algorithm or link to the same generator provided by the target system.
