Is cin << is outdated ?

BinaryByter

C requires more advanced knowledge of underlying concepts of a system. It is easy to fuck up if you don't know exactly what you're doing, however at the end you get a product that is generally faster and able to hook into lower levels of the system. Python is slower and usually less powerful, however it has really nice syntax, lots and lots of modules and a very helpful community. It is much easier to program in and it's my preffered language since it is quick to develop and has a nice way of abstracting a lot of low level things.

good luck keeping your python projects organized

no

BinaryByter

but its not part of conio

std::cin

Is it planned to support utf8 string in C++?

What do you mean?

STL

std::string doesn't support utf8, or does?

Yeah.... Its cin>>

Mat

It does afaik

Mat

Yeah.... Its cin>>

It remains std::cin. Without std:: you're not referring to the standard cin implementation

Elnee

It does afaik

Hmm, thx

std::string is std::basic_string<char>, a single char is not always enough to store an UTF-8 character. Depending on your platform utf-8 is more or less supported. E.g. on Linux you basically can use std::string and UTF-8, size() might however not report what you would expect, it will report the number of char required to store the text, not the number of characters in your string.

I think he was talking about the operator hahaha

Mat

Just to be sure we're talking about the same cin. Sometimes here pops up strange libraries with some esoteric implementations 😂

Hi

Why is it necessary to setup stack n bss

D

Before executing C code ??

Isn that compilers job ??

Hello friends which best book for learning about c libraries

BinaryByter

kek

BinaryByter

bad question

BinaryByter

very bad question

Anonymous

why

BinaryByter

you don't tell us which libraries you want to learn

Anonymous

networks and process

BinaryByter

btw: most libraries have sections with books where you can learn about that lib

can you give me link plzz

Ok thanks

good luck keeping your python projects organized

I'm working on python projects and python libs are kind of loosy (no offense: python & js communities don't do things in a strict way). Backward compatibility and cross platform are what python and JS famous for but they are not guaranteed.

BinaryByter

> python & js communities don't do things in a strict way this is exactly the reason why python is not fit for bigger projects

BinaryByter

you are kinda forced to do everything in a lose way

Jøhn

cout is a method of object std... so it doesn't matter if you intensiate the class or not, you are using OOP...

Using objects != using oop

> python & js communities don't do things in a strict way this is exactly the reason why python is not fit for bigger projects

I and my colleagues did encounter backward compatibility problems and cross platform problems, especially for those low level stuff. (Stereotype) I've been working with other python developers and I guess some of them are not aware of/don't have the knowledge of how things work

BinaryByter

the two things that destroy easy languages more are indeed lack of knowledge and lack of competence

BinaryByter

but backwards compatibility is really IMPORTANT

your variable "string" is never initialized

also, think what happens when the last character of the string is a .

Hi, guys. I need your help. Why temp print works but timeArray.substraction not? Substraction returns Time. What's wrong and how to solve it? If needed there is a code https://github.com/RXDYE/oopLab3

Dima

you need to implement operator << in Time class

Dima

ostream I think

Daniel

yes, it's overloaded so temp(is TIme object) prints ok

Daniel

is there possibly a problem with operators priority? i did not realize what's not okay

Daniel

i made the function returning a link to Time and it's fixed. But why?

I would still prefer not to use the whole namespace but rather using std::sqrt; instead

Raul

This is a different application because you have used it within a scope. And that is fine. However you would confuse people with that line of code and you should leave a comment explaining why you are using namespace std; there. using namespace std; is bad within a global workspace. In this case, you know exactly what you want, so that is fine.

Raul

Typing std:: is the best way to go in my opinion. I would prefer to know exactly what library I am using.

But sometimes you need ADL, typing std:: however does not allow for these lookups. Hence you should be using the functions you want to lookup by it's argument type
