How do I set default values for functions parameters in Matlab?
...n, nargchk, etc. They're useful functions for this sort of thing. varargs allow you to leave a variable number of final arguments, but this doesn't get you around the problem of default values for some/all of them.

Data structure for loaded dice?
... I have an n-sided loaded die where each side k has some probability p k of coming up when I roll it. I'm curious if there is good algorithm for storing this information statically (i.e. for a fixed set of probabilities) so that I can efficiently simulate a random roll of the die.

Is C++ context-free or context-sensitive?
... is (probably) Turing-complete, since it shows a program which is syntactically correct if and only if a given integer is prime.
So I assert that C++ is neither context-free nor context-sensitive.

Why do we need virtual functions in C++?
... a rat."
So far so good, right? Animals eat generic food, cats eat rats, all without virtual.
Let's change it a little now so that eat() is called via an intermediate function (a trivial function just for this example):

void func(Animal *xyz) { xyz-...
