Math.random() versus Random.nextInt(int)
...ution.
Scaling by 6 doesn't alter the number of possible values, and casting to an int then forces these values into one of six 'buckets' (0, 1, 2, 3, 4, 5), each bucket corresponding to ranges encompassing either 1501199875790165 or 1501199875790166 of the possible values (as 6 is not a disvi...
Forward declaring an enum in C++
...ifferent sizes, but I'm fairly sure that data pointers have to round-trip (cast to another data pointer type, then back to the original, need to still work), which implies that all data pointers are the same size.

Using a bitmask in C#

// The casts to object in the below code are an unfortunate necessity due to
