*"Seed uses the provided seed value to initialize the default Source to a deterministic state. If Seed is not called, the generator behaves as if seeded by Seed(1). "* So even without calling rand.Seed your output will be the same everytime you run the program unless you take action to make that different. ( note that the second value obtained from Rand.IntN is not the same as that for the first value obtained from Rand.IntN seeded with the value 2 ) -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
