Or is it just that you're seeing the complete stupidity about it you're now turning?
Wim
I do vouch for good libraries though and using them
Wim
But they shouldn't require an extra 1G of memory EVER
Francisco

You just calm down. If you want to use your own library instead of an already existing one, is your problem.You'll spend a heck lot of time coding it and the results won't be even near to the already existing ones.
We don't have pip like Python does, and that's problem in package management, but you can start trying things like Conan.
Wim
Hold on there
Wim
We're talking about dumb fragments of a number
Wim
You're telling to include a whole library for something thats so easy it should be in a textbook
Wim
Not having pip or whatever is no excuse to that
Francisco
You're telling to include a whole library for something thats so easy it should be in a textbook
If it's easy, there's a lot of chances it's already in the STL

Precision outside IEEE specs pretty much falls out of any specification, so don't expect it to be in it as it tried to adhere to standards
Francisco

If you don't like something about the standard or you feel like something is missing, make a proposal and wait for it to be accepted by the commitee in the next revision

Assuming C, Do you mean like this? Where's your issue? And what has insert to do with it?
int sortStudentById(const void * l, const void * r) {
const struct student * ls = (struct student*)l;
const struct student * rs = (struct student*)r;
return strcmp(ls->id, rs->id);
}
qsort(
stu, 100,
sizeof(struct student),
sortStudentById);
I believe this is just declaration .c file what about your main() file?
Wim
How does that relate to the fact that IEEE encoding is not endless but for the extra precision you'd like to have you can simply write a few lines of extra code instead?

I'd like to know what "a few lines of extra code" means to you
Wim
If you'd put half the effort in writing it as you did in trying to justify the "I don't have to think about it and just grab a library" as you did here, then its a few lines of extra code; if you want to find a good library it'll take hours or even days to make sure its fit for the job which you could've done already, multiple times by now

Again, I'm not going to write a library that's already implemented unless it's for learning purposes or for fun

Why c language is platform dependent? And independent?

Its machine language written in mnemonics to make it understandable for humans

std::string_view doesn't own the string, it's basically a pointer and a length.
Wim
Assembler only distincts between value-sizes, any character is just a value?
MᏫᎻᎯᎷᎷᎬᎠ
std::string_view doesn't own the string, it's basically a pointer and a length.
So
There are no ways of copying?!
olli

Because a char, int and long are all integral value (whole numbers)

True, I think he meant: "Why is char considered integral in the standard documents"

Probably, Olli, I thought he was still going on about Assembler

You can copy a string_view that has the same effect as copying a pointer (shallow copy)

Multiple objects has the same pointer
I thought that was A bad practice, that's why std::shared_ptr exists!!!

But the purpose of std::shared_ptr is different, since the smart pointers own the ressource.
A string_view owns nothing. Imagine you are parsing some text and while parsing you need to pass a substring to some other functions. Either you copy the substring, or you just create a std::string_view which "limits the view" to the substring you want to have

So you mean getting the address of the substring
Mihail

he was clearly just going on about his test questions lol
olli
So you mean getting the address of the substring
e.g. like this.
#include <string>
#include <string_view>
#include <iostream>
int main() {
std::string foo{"Hello World"};
std::string_view first_word{foo.c_str(), 5};
std::string_view second_word{foo.c_str() + 6, 5};
std::cout << first_word << ' ' << second_word << '\n';
}
first_word and second_word are only views into the foo string.
In comparison to only pointes, string_view provides iterators, searching and so on

#include <stdio.h>
int var = 20;
int main()
{
int var = var;
printf("%d ", var);
return 0;
}
Saqib
Predict the output?
Saqib
Answer says: Garbage value
Saqib
The explanation given was "First var is declared, then value is assigned to it. As soon as var is declared as a local variable, it hides the global variable var."
Saqib
What does it mean here to hide the global variable var?
Saqib
how can it hide globall variable...?? also how can int var =var ; be valid statement means how can we assign var to var...?
Tushar
Within the body of a function, a local variable takes precedence over a global variable with the same name. If you declare a local variable or function parameter with the same name as a global variable, you effectively hide the global variable.
olli
how can it hide globall variable...?? also how can int var =var ; be valid statement means how can we assign var to var...?
Shadowing or Hiding works by declaring another variable with the same name in a local block (scope). e.g.
int main() {
int f = 1;
{
// the only f declared is the one set to 1
printf("%d\n, f);
// shadow f in the current scope
int f = 2;
// f has been "shadowed" and set to 2 above
printf("%d\n, f);
}
// the local f (only one exists) has been set to 1
printf("%d\n, f);
}
What's the output here?
It's nothing special to C/C++
https://en.wikipedia.org/wiki/Variable_shadowing
Saqib
Oh okay so according to this the outputs will be 1
Saqib
then 2
Saqib
then 1

Got it.

Thanks

Output is 1 only.
