I have downloaded an .ods file from this website (UK office for national statistics). Because of the way the sheet is structured, I import it as two separate dataframes:

QUESTION
I'm wondering if there's a better way to handling pointers to multiple structs, when you use the structs to overlay data you didn't create yourself. I'm trying to parse an ELF file header (the format is well-known, so I won't reproduce the structs here). So, say you have a pointer to a struct for the file header:
struct elf64_file_hdr *fh;
One of the fields of the file header is `shoff', which is the offset in bytes from the start of the file to the beginning of section headers, or to be more specific, the beginning of an array of section header structs. So, you can have:
struct elf64_section_header *sh;
and access each section header as sh[0], sh[1], etc. The question, then, is how to set `sh' correctly. I've been doing a cast and then recast to make the pointer math work:
sh = (struct elf64_sec_hdr *)((char *)fh + fh->fh_shoff);
But it seems like there must be a more elegant way to do this.
...ANSWER
Answered 2021-Apr-27 at 20:42I don't think there is, beyond wrapping it in a macro. But that doesn't seem too bad. To get around pointer arithmetic you first have to cast away the initial type, then you need to cast the result to the type you want. That's exactly what you're doing.
Here's a macro to do it, casting the result to void* so it will automatically convert to the right type.
QUESTION
Let's say I have a pointer to a struct.
Can I recast this to *char and, assuming I know the size of it including padding, then pass that to some function that could use it as *char (for example write it to a file)?
And is doing that free in terms of overhead?
(No need to tell me this is a bad idea, my question is if it is possible and if it is overhead-free.)
...ANSWER
Answered 2021-Apr-14 at 11:01It is generally legal in C++ and free in terms of runtime costs to use reinterpret_cast(pointer_to_my_value). In place of char you can also place unsigned char or std::byte. As long as you are going only to read this cast data and/or cast it back to original type it is within the bounds of defined behaviour.

QUESTION
I've been enjoying navigating Rust through its type system. But when it goes into macros I find it difficult to follow. In the below example, why is it ok to pass "target_name" to target but not assign it then pass the assignment in? How do you navigate the macro in tracing such that the below is obvious to you? I am asking this as much from a developer experience perspective as a programmer. (I'm definitely looking for a "teach a man to fish" style answer.)

ANSWER
Answered 2021-Mar-17 at 16:24auto is just a placeholder for a compiler-deduced type, depending on the context in which auto is used.
In your example, you can't use auto as the return value of my_f_params::inter_auto(), because the compiler has no way to know what type inter_auto() actually returns, so it can't deduce the type of the auto. You would need to do this instead:
QUESTION
I am trying to approximate pi for homework by using a Monte-Carlo method, by randomly sampling points in a unit box, and counting the ratio that falls inside a unit circle enclosed by the box. See below. I am asked to do this in parallel using multithreading but decided to get things working first before parallelizing things. My teacher has hence explicitly asked me to use rand_r() for thread safety. I am aware that better pseudo-random number generators exist. However, I cannot seem to get things right, and I figure I am seeding rand_r() the wrong way. I have tried to seed using the computer time, but the value I get is wrong (around 2.8). If I use some random number and seed rand() with srand() instead, I am able to approximate pi pretty easily. Can anyone enlighten me as to what I am missing here? The code I have written looks like this:
...ANSWER
Answered 2021-Mar-01 at 20:26You are:
reseeding the random number generator on each iteration instead of letting it do it's thing, and
not only are you reseeding each iteration, you use the same seed for
xandy, so you're only creating elements on the diagonal (wherex == y)EDIT: in the original question you used
randomNumber(iteration), which would generate sorta-random numbers on the diagonal, in your edit you changed it torandomNumber(seed), which is always the exact same value.
Change the definition of randomNumber:
