unsigned char add(unsigned char a, unsigned char b){ for (int i = 0; i < b; i++) ++a; return a;}stupid way to add, but it does satisfy the requirements.
Tricky C++ questions
1. How do you add with out using addition, subtraction, modulus, multiply, divide operators.

Thanks for all the ideas!
I just finished a few hours ago and they didn't really ask anything hard. the "hardest" thing that they asked was "what's the difference between overloading and overwriting":)
What is this overwriting you speak of.
>int a =1;
>std::cout << (++a + ++a + ++a) << std::endl;
Questions like that might be interesting - but (together with all
the really low-level questions) they are unsuitable for an interview.
Most of them are 'gotcha' questions and it's really unfair to do that
to a nervous applicant - you should try to make an honest impression
of if the person is up to the job.
Besides that, whoever would use stuff like that (without detailed
comments) in real-life production-code should NOT get the job.
Just my 2ct.

He probably meant overloading and hiding.

Or possibly overloading and overriding. I have been asked that question in an interview before.
So the interview questions of today are limited to low-level jabbering? No questions about inheritance versus composition, design patterns and such?
I mean, I can understand why such hidden-gem questions can be usefull, it's one way to see who's actively developing him/herself and who isn't, but I'd say it's just one side of the equation... or perhaps better said, one of many facets. :)

Well, a slightly more efficient addition algorithm, for no particular reason other than I'm bored:
Oh, and before somebody points this out, I'm aware it's twos complement only and therefore not standard compliant.
int add (int a, int b){ while (b != 0) { int x = a ^ b; int y = a & b; a = x; b = y << 1; } return a;}Oh, and before somebody points this out, I'm aware it's twos complement only and therefore not standard compliant.

At the last game-dev company I was interviewed for, the first interview consisted of a 1hour exam on on this jabbering, then the second interview was on design patterns, the third interview was on character/personality.
