I honestly want to work as a freelancer

Me too!

I dont want to follow others orders

Except its hard to be a coder and freelancer at the same time its nearly impossible

Have you read the book Hackers&Painters？

Tbh never heard of it

Im actually focusing on algorithms

you will love it

Thank u i will add it to my list

wow, is't awesome

Thats why ur nickname is little artist

U got inspired by the book

😉

hahaha

Have u read the art of intrusion by mitnick

Actually, it's inspired by a team of Dota2 named Cloud9

Woooow

So u are a gamer

And a coding engineer ..nespresso what else?

ko is really positive

Tbh never heard of it😁

I play dota every week

Hey joe thnks buddy..we all need positivity nowdays

one of my hobby

ko how old r u

I actually cant play for a while i fried my laptop charger so im using an old rig ..

I see

What about u

I forgot to mention food

Lmao

Anyone know telegram groups for image processing or similar?

How do you guys deal with namespaces? Do you put files in according folders?

solution structure and namespaces are usually a different thing, BUT sometimes they match

Will it be possible that matrix features would be supported in C/C++ without using externel libs in the future?

hi Is there a way to overload a pure virtual functions in C++? I want in the base class 2 virtual function with same name but different arguments who inerhit the class should be choose which of two functions override

explain "matrix features"

Like glm::matrix?

hi Is there a way to overload a pure virtual functions in C++? I want in the base class 2 virtual function with same name but different arguments who inerhit the class should be choose which of two functions override

you can overload virtual functions. not sure if you try to apply that overload for the right thing

can you demonstrate what you are trying to achieve?

can you demonstrate what you are trying to achieve?

i want for example virtual int fun() = 0; virtual int fun(int &errorecode) = 0; and who implements the class should be able to choose if he wants errcode or not

and how client will be sure that derived class implements right function?

suppose that derived class does not implement fun(int &errorcode), and user calls p->foo(err) what should happen?

because he derives the class

so if he wants use errcode else not

I mean, you will lilkely use pointer to base class, right? What you expect when somebody or somewhere will call non-existing function?

compile error

That's impossible to achieve in compile time. Inheritanse is run-time stuff.

You can throw exception instead

You only can get compile error if derived class does not implement *all* pure virtual functions

That's impossible to achieve in compile time. Inheritanse is run-time stuff.

It is not C++ related stuff, it is just how run time binding works. Run-time.

so what can I do to allow user to choose if use a function argument or not?

virtual int fun() { throw std::exception("Not implemented!"); } virtual int fun(int &errorecode) { throw std::exception("Not implemented!"); }

in base class

if you don't want for object of base class to be created

add

base() = delete;

#include <iostream> using namespace std; int main() { cout << "Enter a year: "; int year; cin >> year; switch (year % 12) { case 0: cout << "monkey" << endl; break; case 1: cout << "rooster" << endl; break; case 2: cout << "dog" << endl; break; case 3: cout << "pig" << endl; break; case 4: cout << "rat" << endl; break; case 5: cout << "ox" << endl; break; case 6: cout << "tiger" << endl; break; case 7: cout << "rabbit" << endl; break; case 8: cout << "dragon" << endl; break; case 9: cout << "snake" << endl; break; case 10: cout << "horse" << endl; break; case 11: cout << "sheep" << endl; break; } // after 12 years zodiac's color green And then yellow, black, white How can i do that please help return 0; }

Like that Dog = green

what?
