Great, now we can read it but it doesn't make any sense

.

Rab all

what?

Write a program to print the mark list of the students each record contain roll number ,name ,and total mark

First, we won't do any of your homeworks, second, that also doesn't make any sense

Cpp have some package manager? Like pip in python, yaourt in arch linux e.t.c

it has many, conan is one of them, but i prefer to use cmake externalProject to manage them

Not homework

this is your assignment

and it’s easy tho

No

No

Do it yourself and if you have questions, you can ask

Folks, advice my please some awesome workshops or cookbooks for learn c++ on practice

Something like this

Omg

Some thing like using arduino

or something else interesting

Without unreal engine lol

are there any functions to insert text from the keyboard to save it in a string variable?

Yeah

why this error

"I want a list, not a linked list, how to get that in C++?"

Is there any android app were I can try c program

termux

Can we install gcc on termux?

Yes

[Error] request for member 'c_str' in 's.std::basic_string<_CharT, _Traits, _Alloc>::operator[]<char, std::char_traits<char>, std::allocator<char> >(((std::basic_string<char>::size_type)i))', which is of non-class type 'char'

what does it mean

string conStrBin(string s){ string s1; for(int i=0;i<s.size();i++){ s1+=bitset<8>(s[i].c_str()).to_string<char,string::traits_type,string::allocator_type>(); } return s1; }

Bladee fuckerss🔥🍕

/warn unsure

template?

yes

and i use to_string

i solved ahahahha, string conStrBin(string s){ string s1; for (int i=0;i<s.size();i++) { s1+=bitset<8>(s[i]).to_string(); } return s1; }

32/5000 should I use int or size_t?

and i use namespace std

OK thanks a lot

is the stoi function contained in the <string.h> library?

I saw from the link you shared that the other fields can omit them, but does not recognize that function. why?

How should I do otherwise?

Use atoi

But meh

You have to write the char* into the string in that case, but rather try to use a more up to date compiler and version of C++ if possible

C++03 is 15yo

And C++98 is old enough to buy its own beer

on the left is the string containing the binary value and on the right the result of the atoi function, is there no way to get that same value?

on the left is the string containing the binary value and on the right the result of the atoi function, is there no way to get that same value?

So you want to parse a string that represent a binary into that number if I understand correctly?

Yes

The string for example is "10010101" , my int variable must be 10010101

The string for example is "10010101" , my int variable must be 10010101

http://www.cplusplus.com/reference/cstdlib/strtol/ string a = "10010101"; char* ingnored; uint64_t value = strtol(a.c_str(), &ignored, 2);

I know but I want 1001010 , but my int is worth a decimal number, it certainty implies the decimal value

You don't provide an actual value when you use it, just a pointer

You don't provide an actual value when you use it, just a pointer

And well it is not used for memory safety within the function but as an out parameter

But since one may want to compare it with a.c_str()+a.size()...

I know

The function will initialize it

If it were me I'd do string a = "10010101"; char* consumed; uint64_t value = strtol(a.c_str(), &consumed, 2); if(consumed==a.size()+a.c_str()) { //The string have been entirely consumed }

Because generally your string is not just solely a number

Using C functions at all is unsafe

just add the special ingredient called _s and you are good to go

Which is why I also advise to update his standard

just add the special ingredient called _s and you are good to go

Or just use C++ and a range based number parser like a sane person

But in case of error you will at least be able to do stuff and will not crash over an absense of null terminator

But in case of error you will at least be able to do stuff and will not crash over an absense of null terminator

And if you are just a little bit cunning you parse a string_view that limits the number of digits usable to the actual range the user will want

Hi guys, I'm new to C and to the channel. I have a question about fgets() reading from stdin.
