Hello techlovers 😍
I m a tech savvy 🦸♂️
Feel free to talk me your trouble at laptop 💻 & desktop 🖥
I think... that you haven't read the rules of this group

Actually I read not to sell anything

Relax I m not selling anyone to anything

Just introduced my self

which just shows that you are ignorant about the rules, that's why i mentioned to read them, thank you

sounds reasonable

Please help me, how can I give an array as variable to some function? In C

in C array is just a pointer to data, so just pass the pointer

but how can i go through it to get some element?

Have you even tried googling?
PhD
but how can i go through it to get some element?
I suppose it's some kind of a school assignment, you'd actually need to learn some basics, but if it's urgent, try solving the problem with chatgpt.
To iterate through an array use a for loop, but I don't think it's big of a help for you.
Danya🔥
yeah but i have readed it bad

thx for a lot

iterate over it until you get the delimiter or just pass the size as a parameter

Hi, I don’t know much, so need a help.
How can I write the html inputs value into a .txt file?
.
Like someone put abcd@gmailcom into a email input, what I do to it be written into a .txt file?
klimi
Like someone put abcd@gmailcom into a email input, what I do to it be written into a .txt file?
what do you mean by email input? if you are asking in c or c++ how to write to file, you ask operating system to do it for you or you use some library functions

No I’m talking about html and JavaScript
klimi
No I’m talking about html and JavaScript
No, you are not. This is C/C++ group so you must be talking about c/c++
No I’m talking about html and JavaScript
User DAC01N has 1/2 warnings; be careful!

So why do you here? In C/C++ chat
My bad, thought it was more embracing, in the invite I got it says general questions, sorry again
.
Alright

How are chars compared in c?
char to_upper(char c) {
if (c >= 'a' && c <= 'z')
c += 'A' - 'a';
return c;
}
H
How can the char c be greater than 'a'?
H
Or are all chars converted to a number?

literally uint8_t

They can be signed or unsigned depending on a platform
H
Ok, thanks 👍

they can also have as many bits as platform-defined (or compiler-defined? Char size isn't defined in standard), yup. But how to describe chars then?

They are described using the type char, set to describe both exactly one byte of memory (byte as defined by a type of CHAR_BIT bits), which is an obscure type
H
while (*str1 && *str2) {
if (*str1++ != *str2++)
return 0;
}
return (*str1 == *str2);
}

What happens when you && two pointers??

Or logically compare two pointers

CHAR_BIT ≥ 8
okay, at least 8. But at least means, that 64 bits would also be a standard-compliant char size
\Device\NUL

*(ptr + x) is basically ptr[x] and *ptr is same as ptr[0]
Danya🔥
not 8, 7
char must be able to hold UTF-8 code point or whatever the smallest thing in UTF-8. It requires 8 bits.

Yes
It's the case for some DSP processors.

or ascii. Extended ascii also uses the whole 0-256 range
H

Oh, so the values in the pointers are compared, right?
Ludovic 'Archivist'
char must be able to hold UTF-8 code point or whatever the smallest thing in UTF-8. It requires 8 bits.
Be careful, because this bit of the standard is a bit broken, it requires that char be able to represent UTF-8 codepoints that are strictly lower than 128, which can be represented in 7 bits, char8_t is required to be considered a narrow type but it is not required to be the same as char
Кіт ✙
Yes
It's the case for some DSP processors.
so is it platform-defined with a hint, that almost always 1 byte
\Device\NUL
char is guaranteed to hold ASCII char from what I learned
Ludovic 'Archivist'

In C, the format is not mandated, in C++, de facto, ASCII is required (for versions of C++ after 11 if I am not mistaken)

Thanks for correcting me, that is a huge change in what I need to support now

It was there in C++17
I'm currently looking into the final draft of C++17 and "eight-bit" is there

I've never read it fully I'm not a psychopath, but this requirement was there for as long as I can remember. I think it should've been added in 11 or 14

The hard requirement seems to actually have be authored for C++17
Ludovic 'Archivist'
before there was a clause that was in the footnotes about only the 0-127 range of UTF-8 being supported
