Please take another look at the documentation you linked to.

The docs for rand state that it "Automatically calls srand unless srand has already been called." It is not necessary to call srand manually and doing so may actually reduce the randomness of the sequence your receive. (If you call srand repeatedly, it will almost certainly do so.)
