In case you didn't want to go to the trouble of running code, the problem is that the C++ preprocessor does a simple text replacement, so something like 6 * ADD(3, 5) becomes 6 * 3 + 5, which is 23, not 48 like you would think to look at it. The usual way you would correct this is to add some brackets in the macro definition: #define ADD(x, y) (x + y)

Oh, I should have known that.

An even "more correct" way to write that macro would be #define ADD(x,y) ((x)+(y)) since, again, you can be bit in the rear end for certain values of x or y. While macros are not evil per se, they do open a can of worms if left unchecked, a relatively hard to debug can of worms.

hobbesmaster posted:Unions are also classes if we're talking about C++ trivia. At a language implementation level they're quite similar; it's just that the offset from the memory address of the variable for all their members is 0 and the size is the largest size of any given member rather than the sum of the sizes of the members (modulo alignment adjustments).

I was asked but then followed up with this more trivia type questions, it was really a bit tenuous. They still want to interview me which suggests there are not a lot of C++ people really looking for jobs.

ExcessBLarg! posted:But is your average C++ codebase "better" than your average Java codebase? How much C++ do you encounter in the wild that's modern C++11? I feel like C++ allows for a wider range on the "better" spectrum, ranging from horrifying to pleasant. Java seems to condense the range around annoying. I'd rather work with tools that can be nice, rather than tools that prevent me from losing limbs but remain generally unpleasant.

I've been really lucky, every interview I've done from either side has been pretty good. The only exception was for my first job moving from low-level C stuff to web dev about ten years ago. All their questions were stuff I'd learned by googling 'asp.net interview questions' the night before, and then their lead asked how I'd add a repeater control to a page and I just said 'um...I'd type 'repeater' into the aspx file?' wondering if it was a trick question or maybe they'd ask me to expand on the page life-cycle or something, but nope, that was it, job done. When the recruiter got back to me he said they though I sounded like someone who could really 'go places' in the company and offered me a senior role
