Hi,

I found this code for shuffle one-dimensional int array somewhere:

void shuffle(int *array, size_t n)
{
    if (n > 1) {
        size_t i;
	for (i = 0; i < n - 1; i++) {
	  size_t j = i + rand() / (RAND_MAX / (n - i) + 1);
	  int t = array[j];
	  array[j] = array[i];
	  array[i] = t;
	}
    }
}

How can I make change to this function to shuffle 2-dimensional array. This is the declaration of the 2-dimensional array I need to shuffle.

char list[2000][20];

This array is an array of string (20 char max). I need to shuffle the outer array not the inner one.

Any help would be really appreciated,
Pat
