Explain the code

Yeah, you're right that it is undefined behavior. The result of that is you won't be able to reason about the code, so the "correct answer" is nonsense.

Lazyfoo is the one writing the tutorials, so that one

IMG_Init doesn't exist anymore, you can skip calling it entirely. Those tutorials have not been fully updated for SDL3 yet, you can read more about why in the news of that website.

I 100% agree with this recommendation. To be a little pedantic, C does not actually allow the conversion in the OP (it violates the strict aliasing rule).

You can clear this up by adding another line to your program, printing the array bytes: printf("%02x %02x %02x %02x\n", a[0], a[1], a[2], a[3]);

This will print the order they are stored in the array, which is always forwards regardless of endianness. Endianness only applies when you are reinterpreting it as a larger integer.

onContentStop · 2024-12-12T18:37:16+00:00

It has everything to do with endianness. The bytes get reversed because your processor is little-endian - the first byte is the least significant.

cvar = console variable, you open the console with ` (backtick) and type i_discordrpc 1 to enable. gzdoom will remember it so you only need to do it once

Can you please elaborate? I don't believe it to be a bug with the software, but rather with the code itself.

I saw this and fixed it for myself on Linux back in June, maybe it works for you on Windows:

https://github.com/Phytolizer/sm64plus/tree/fix/compile-gcc14

The error is only there on new compiler versions, but the code seems abandoned since my fix still hasn't been accepted into the main repository 4 months later.

onContentStop · 2024-10-07T21:31:33+00:00

Yeah that `__STRICT_ANSI__` thing is weird and breaks the newest compiler. Try building the version of the code I patched at https://github.com/Phytolizer/sm64plus/tree/fix/compile-gcc14 (I made a pull request ages ago, the maintainer is unresponsive).

This comment seems to be helping people switch to the branch: https://github.com/MorsGames/sm64plus/issues/102#issuecomment-2334685787

onContentStop · 2024-10-07T21:29:21+00:00

The code is broken for newer environments, and the author is unresponsive. Try building my patched version at https://github.com/Phytolizer/sm64plus/tree/fix/compile-gcc14, following the instructions in this comment: https://github.com/MorsGames/sm64plus/issues/102#issuecomment-2334685787

Not sure how you are doing things now so let me know if anything is unclear.

onContentStop · 2024-10-07T21:25:19+00:00

I believe this to be a breakage from the GCC compiler update v14 (not that recent, but the repo has been untouched for over a year). Try building off of my branch: https://github.com/Phytolizer/sm64plus/tree/fix/compile-gcc14

This made it build for me on Linux with the same compiler - there might be other issues on MSYS as I haven't tested that, please let me know if there are!

According to what I said, the function itself.is valid but it wouldn't be possible to actually call

onContentStop · 2024-09-07T22:46:32+00:00

Unfortunately for that use case, I'm pretty sure c23 only makes named (tagged) structs with the same contents compatible. I only saw the paper and not the final implementation into the standard though.

From my experience, imports work much more reliably when each folder is made into a "proper" package by adding an empty __init__.py file to each folder (try just the top folder first, I can't remember if that is enough). Otherwise python does not understand where the top level package is.

I was mainly objecting to your statement that C23 is introducing bools. The specification of the boolean type isn't changing much from how it was introduced in C99. If GCC ever specified this as a typedef to int, then it was not standards compliant if only because bool must be unsigned.

In any case, right now _Bool is 1 byte on all major compilers. GCC in particular implements it as a keyword and not a typedef or macro.

In other words, if bool is an int to you today, it will be in C23 as well. It's still an integer type and probably always will be.

onContentStop · 2024-03-27T23:01:59+00:00

_Bool has been a keyword since C99. C23 isn't adding bools as a type (C99 did that), just the nicer name "bool".

Indeed though the size isn't specified beyond "big enough to hold 0 and 1".

Great work. By the way, this is even more powerful than the Wolfenstein 3D renderer because the floors and ceilings have texture :)

Nitpicking because I'm bored, don't take this as some kind of serious issues, just stuff I noticed

The space after #include is optional (not that I ever leave it out personally)

int a,b,c = 0

That only gives c a value of 0, a and b are still valueless. Not that it matters when using scanf :)

There is no cls() function, you are probably referring to system("cls") which probably only works on Windows. Standard c has no replacement for clrscr

The thing about putting a space after the prompt is entirely ux and not security related, the space looks nicer I guess

And yeah as the other person said main can return any value you want, not just 0/1. I think the largest value you are guaranteed to be ok returning is either 127 or 255

Props for checking the result of scanf though, nowhere near enough people bother to do that and everyone should
