int inBetween2{ 0 };
for (int i = 1; i < MaxNum; ++i)
{
if (static_cast<unsigned>(num - randVec[i - 1]) <= (randVec[i] - randVec[i - 1]))

What exactly do “u” and “r” string flags do, and what are raw string literals?
...by calling unicode('text')

How to check if an object is nullable?
... I just verified; this does not work, as Jeppe said. If the variables are cast to object, it will always return false. So you cannot determine the type of an unknown object at runtime this way. The only time this works is if the type is fixed at compile-time, and in that case you do not need a runt...
