Any thoughts on gitea?

Hello guys someone can help me with a simple c code?

A simple like hello world #include <studio.h> Int main{ Pprintf("hello world"); }

😐

Why there is a type conversion error ?? And how to solve it ?? Error says : no viable conversion from '__gnu_cxx::__alloc_traits<std::allocator<std::__cxx11::basic_string<char>>, std::__cxx11::basic_string<char>>::value_type' (aka 'std::__cxx11::basic_string<char>') to 'int' vector<int> v1{1,2,3,4}; int v1_size=sizeof(v1)/sizeof(v1[0]); string str=""; for(int i=0;i<v1_size;++i){ str+=static_cast<string>(v1.at(i)); }

yeah, should be int v1_size = v1.size();

So this error is not because static_cast rather than v1_size here?

or size_t v1_size = v1.size(); to be precise

Hello

I'am beginner, please can you send me execises.

The group is majorly directed towards answering questions, not teaching or practicing stuff But you can check out website called codewars, it has plenty

Hey does anyone prefer c++98 to this modern junk

#include<iostream> #include<string> using namespace std; class binaary{ private:string s; public: void read(void); void check_binary(void); void complement_num(void); void display(void); }; void binaary :: read(void){ cout<<"input your num"; cin>>s; } void binaary :: check_binary(void){ for(int i=0; i<= s.length(); i++){ if(s.at(i) != '0' && s.at(i) != '1'){ cout<<"not a valid binary format"; exit(0); } } } void binaary :: complement_num(void){ for(int i=0; i<= s.length(); i++){ if(s.at(i) == '0'){ s.at(i) = '1'; } else{ s.at(i) = '0'; } } // cout<<"your complement number is"<<s; //this wont return your s i have tried so we use display function } void binaary :: display(void){ cout<<"displaying your binary num"; for(int i = 1; i<= s.length(); i++){ cout << s.at(i); } cout<<endl; } int main(){ binaary g; g.read(); g.check_binary(); g.complement_num(); g.display(); return 0; }

It should be std::vector::size_type actually. This is where using auto helps

> for(int i=0; i<= s.length(); i++){

Yes..?

But the online tutor had the same code... His code ran mine didn't

it must be undefined behavior

He used at member function

Modern C++ is waaay better than 98

Templates are turning complete. You can write a parser using them

Modules. So you want c++ to be like python now? Ok yeah i get you..

the c++23 standard should be as a different language lol imo

Which app can i used for coding c

hard times create strong programmers strong programmers create weak languages which are being used by weak programmers weak programmers create hard times

You do know why modules are preferred(modern languages like Rust in general) over header files right?

An ide

Yeah, but life is short lol

The language is being abandoned Rust is taking over I've seen a lot of programmers turned to Rust

Which type

Rust has an ugly syntax and is too verbose like your c++20

Any C/C++ ide. In windows, VS Studio. If you are comfortable with text editors, then VSCode

Lol i said android i dont have pc

Depends. Since in my knowledge, most Rust programmers are usually blockchain Dev's for some reason.

I'm not a Rust Dev, I really would love for C++ to get over from its dirty hole, but the committee just don't get it
