something is wrong in the code

Write a program that will get all the prime numbers that were written before that number in the input. The numbers displayed must be separated by a space

hello?

hello?

Hello.

what's the return type of std::basic_string::size ? If I am not wrong I think it's std::uint64_t please correct me if wrong

Hello.

I can’t write this code, please write you

I can’t write this code, please write you

Are you an idiot?

I can’t write this code, please write you

I suppose its good idea to ban guys like this

who asks write code, look for errors in code etc

can anyone help me??

Hello.

😔but why am I trying but nothing i am a girl

Write a program that will get all the prime numbers that were written before that number in the input. The numbers displayed must be separated by a space

go read about sieve of eratosthenes and learn

😔but why am I trying but nothing i am a girl

what you think that kind of thing will work here, miss?

what's the return type of std::basic_string::size ? If I am not wrong I think it's std::uint64_t please correct me if wrong

not sure that it is specified as I see it depends on the allocator used

😔but why am I trying but nothing i am a girl

Oh I didnt know you're a girl! That changes everything

Oh I didnt know you're a girl! That changes everything

:D

hmm... because at all places they were showing like numbers of charT elements in the string

hmm... because at all places they were showing like numbers of charT elements in the string

Yeah

or like size_type

or like size_type

this I think is just notation

https://en.cppreference.com/w/cpp/string/basic_string/max_size

https://en.cppreference.com/w/cpp/string/basic_string/max_size

lol not that, but I think in my case it'll turn out uint64_t

anyone knows c++?

please answer?

Well the max size would man what the variable type is no?

anyone knows c++?

Like nearly everyone in this group - people who have just interest but they dont want to learn

I can’t write this code, please write you

what the purpose of doing the assignments you are sending to us? 1) to learn? then you should do them yourself and try to understand how it is working and why (we can answer questions about "how" and "why" if you are able to ask them). 2) just to copypaste our solutions and pass the assignments? well, then you've chosen the wrong place

you're right

what's the return type of std::basic_string::size ? If I am not wrong I think it's std::uint64_t please correct me if wrong

actually it's like this, std::string some_func(std::string text) { int j = 2; // I already know that text.size() > 5. auto x = text.size() - 2; return text.erase(4, 1);

I will try

actually it's like this, std::string some_func(std::string text) { int j = 2; // I already know that text.size() > 5. auto x = text.size() - 2; return text.erase(4, 1);

it's a random func I just made up, there I'm curious about type of x

I will try

read about Sieve of Eratosthenes in your case at least for that problem

anyone knows c++?

/get cbook

Give it a shot buddy!

BTW they say using unsigned data types should be avoided, I know reason, but should I still avoid even if I know that none of the value (be it anything) is going to be less than 1, let alone negative

who says like this? please provide the link

https://www.learncpp.com/cpp-tutorial/unsigned-integers-and-why-to-avoid-them/

It's generally laziness or lack of understanding. I aways use unsigned int when the value should not be negative. That also serves the documentation purpose of specifying what the correct values should be.

from your link

when it can be error-prone to do some stuff with unsigned, they are OK in cases when you sure that they can never be underflowed (and preferably you have good static code analysis that can prove that).

yeah then I'm fine in my case, as I'm pretty sure that it would never underflow

it's all strings mainly

for example size_t is unsigned

for example size_t is unsigned

yeah

for example size_t is unsigned

so this one should be all fine right? Sorry to make you look through that

so this one should be all fine right? Sorry to make you look through that

by the way, you can do something like using string_size_type = std::string::size_type; and use string_size_type instead of std::uint64_t.

otherwise the real size type can be different on some other platform than you use now

what's the return type of std::basic_string::size ? If I am not wrong I think it's std::uint64_t please correct me if wrong

std::basic_string is a template. if you mean std::string (basic_string<char>), then the return type is std::string::size_type

so this one should be all fine right? Sorry to make you look through that

just use decltype(text.size())

so this one should be all fine right? Sorry to make you look through that

I would use size_t instead of uint64_t

so this one should be all fine right? Sorry to make you look through that

and then decltype(j) for i

so this one should be all fine right? Sorry to make you look through that

btw this entire function can be simplified to text.erase(std::stable_partition(text.begin(), text.end(), std::isalpha), text.end());

don't write Turbo C++ code. come to the modern age

At least there are no graphics.h and conio.h :D

Oh thanks, i knew about isalpha i wonder why i didn't use it there

Oh thanks, i knew about isalpha i wonder why i didn't use it there

actually sorry that's not enough. you still need to transform (std::transform, std::for_each, range based for loop) the entire thing to uppercase. lemme see if that is possible to do that with a one-liner.

Yeah ikr

ye i guess this is faster than using 2 algorithms

Sameer Khan, Hello guys , I want to know more about enum can anybody explain me in detail please help me. Sameer Khan, Please🙏🙏

what's the return type of std::basic_string::size ? If I am not wrong I think it's std::uint64_t please correct me if wrong

std::basic_string::size_type is the return value type

I think in most or all implementations it's the same as std::size_t

how to integrate with monte carlo method

what? why i gave warning?

please answer?

apparently no one here

https://en.cppreference.com/w/c/language/enum https://en.cppreference.com/w/cpp/language/enum

Actually I have seen it but what is the use of that I don't know that bro can you help me on that

Are you an idiot?

he is

https://en.cppreference.com/w/c/language/enum#Notes

Bro what where in can use that??

Bro what where in can use that??

lmao that's up to you and what you are doing

Actually I have seen it but what is the use of that I don't know that bro can you help me on that

it will answer your question. you just have to try a little bit. or is this a homework question and copying from cpp reference is too obvious

it will answer your question. you just have to try a little bit. or is this a homework question and copying from cpp reference is too obvious

Nope bro it's means a enumerator

lmao that's up to you and what you are doing

But that the my question where I can like if I have to assign the variable first so I can make the array and do that.

Like : enum director { A1, A2, A3}d1; Int main() { Int A1= 0; Int A2 = 1 ; Int A3 = 3 ; }

Like : enum director { A1, A2, A3}d1; Int main() { Int A1= 0; Int A2 = 1 ; Int A3 = 3 ; }

Isn't they are same??

Like : enum director { A1, A2, A3}d1; Int main() { Int A1= 0; Int A2 = 1 ; Int A3 = 3 ; }

i don't understand what you are trying to do

sorry
