I know that if I use rand()%n + 1 I get a random number from 1 to n, but each number has an equal chance of showing up. Are there any function so get different probabilities besides a flat one? Such as a normal or poisson where you could set the mean and standard deviation (think back to stats class ). Thanks for any help, --Vic--

There are plenty in the Boost library. Not only distributions, but different random number generators as well. Ones which do not suffer from rand()''s flaw (doing rand()%n is bad).

Go there and download if not the whole library, at least the rng headers.
