For example GCC for x86 carries some x86-specific headers specifying those types, GCC for ARM same thing ...

but if there is a computer with the char size 2 byte how do you make a type with size 1 byte if char is the smaller type in c

Does anyone group programmers
For node js or js

If some *rare* architecture has char to be 2 bytes in size either one of these situations may exist:
* uint8_t is undefined
* uint8_t is actually sized 2 bytes, this can be done for cross compilation compatability maybe
But I don't actually know well because I have never dealt directly with this situation

and do you know if its possible to make use an half byte in c

but there is a vm written in c with an an instruction to write 4 bits in a register

If you're interested in manipulating bits have a look at bitwise operation, struct bitfield
/
is it with bitfields
Anonymous
Base size is always 1 byte, you may make only meaningful usage of the lower 4 bits, the remaining ones' state is left unknown and irrelevant to the state of the program
/
yes

i think that the vm to do that uses bitfields

and in c do volatile register place a value always in a register
Anonymous
You leave the work of manipulating bits to the compile's implementation
Anonymous
and in c do volatile register place a value always in a register
If compiler strictly follows the standard, yes, it will find a way to do that
Anonymous
But you may check using a disassembler

But you may check using a disassembler
i know that volatile makes the compiler ignore the optimizations
Anonymous
I think it may even depend on the optimization level, volatile should be used only if you are sure that you can really do better than compiler
Anonymous
Also note that both register and volatile are just hints, that are most likely ignored on aggressive optimization levels

but they told me to use uint8_t instead of char because char may change between different computers
uint8_t will behave as if it had 8 bits. char will be exactly one byte which can be 7, 8, 12, 24, 32 or any other exotic number of bits.
Ludovic 'Archivist'
the "least" int types will have at least the specified number of bits

anyone who knows file handling with fscanf
need help to create a if statement to check first char and set up fscanf according to the file format.

Https is not that easy to implement without using OpenSSL or another crypto library to be honest. I would by no means recommend that to a beginner
DaviChan
Projects for beginners in c++?
I love game projects. You can make them as simple or as advanced as you want. And you can find good use for any feature you might be learning at the moment
DaviChan
You can start with tictactoe and work your way up to maybe a raycaster fps or even a full 3d game when you know most things and can manage to learn about vulcan or opengl also
DaviChan
Textadventures are pretty fun also if you have a good story tell
DaviChan
Pseudocode can be any style. It is not strictly defined to my knowledge, so if C++ is your style of pseudocode 🤷🏻♂️
DaviChan
Also can we establish to share larger code snippets through github or something?

The error you mentioned has got nothing to do with the file you have shown. How do you expect us to help with that?

It is one of the rules here and is mentioned clearly in the pinned post. Just that people don't bother following that which is why their posts disappear.

What is the output of
ldd <your app name> for libcuda.so? Does it say not found?
If you know where libcuda.so is check the environmental variable LD_LIBRARY_PATH to see if that directory is present. If not add it there.

Oh you mean the linking itself is failing.
Try passing -L/usr/lib -lcuda to gcc

i tried it but not work
the compiler said undefined reference to `__cudaPushCallConfiguration'
后藤
when i use "-i/usr/lib/libcuda.so"
compiler says that /usr/bin/ld: can not find -l/usr/lib/libcuda.so

when i use "-i/usr/lib/libcuda.so"

I also have that issue.
I didn't bother much because I don't use my nvidia card on wsl2.
Maybe try looking here.
