Random Shuffling Code Snippet

[iCountNTrack]

The following is a snippet of the random shuffle I use in my BJ programs. I user the Mersenne Twister but obviously you can use any RNG with it.

void shuffle(std::vector<short> & shoe)
{
	short N = shoe.size();  // number of cards in shoe
	short i, j, max, temp;
	for (i = N; i > 1; --i)
	{
		max = i / 2;
		j = floor(max + myRNG(max)); // random index j
		temp = shoe[j];
		shoe[j] = shoe[i - 1];
		shoe[i - 1] = temp;
	}
}
