To handle any number of dice, we create a
std::vector
container. This will be
our temporary die-roll storage location. The number of dice that we are going to
roll is set by the number that we want to consider for our result (
NumDie
) plus the
number that we need to accomplish the skew (
SkewCount
).
After filling this vector with all the die roll results by calling our original
SingleDie()
function, we sort the results. Depending on which way we are skew-
ing the curve, we then move the endpoints of the dice that we are going to consider.
For example, if the results of 4d6 rolls are [2, 3, 5, 6] and we are only going to be
dropping the lowest, we would only want to consider the second through fourth
positions in the array. (Note that the vectors are zero-based arrays, so we would be
