well at least I tried to help him but he seems to be silly
I don't think what he will keep it too long (be unbanned).

Function ("abcd");
How can we modiify the literal in C

How to create a student database using tree structure in c of several classes with several sections.
If you mean Relational database, they are not related to C anyhow, except they are written in C mostly.

anyone knows OOP in Cpp?

Wtf lol

Guys is there a way to declare a constexpr std::string? Should I use a string view instead?

In C++20 there's a constexpr std::string
But if you want to store just a string literal, constexpr std::string_view will be applicable (since C++17)

Alright thank you! I'm so hyped on c++ 20 especially on concepts and modules!
Ilya
Mar!o
Me too I think they a nice modern way to replace the header system and they will also clean up the post processor hell. Why do you think they suck?
Dima
bringing all that hipster stuff from higher level languages, eh?
Dima
I wonder if at one moment cxx will turn to unsafe c# code
Dima
lol, nah
Mar!o
I understand your point but I think there are still many things in C++ which could have an modern overhault
Mar!o
Sure you are right I for example would hate It if they would add Garbage Collection or Reflection
Mar!o
But Modules make things cleaner - no more forward declarations, no more macro redefinitions, cleaner code
Dima
Dima
well reflection already exists in some meaning
Dima
but we can turn it off
Mar!o
Would be a shame if we couldn't ;)
Mar!o
What do you think about concepts?
Anonymous

They promise compile-time reflection to C++26 standard
Mar!o
Jesus... hopefully it's possible to disable it
Mar!o
There is really no need for reflection - iv'e written dynamic modern game engine gameplay systems without reflection - reflections is a nice tool but not needed in c++
Mar!o
Not... oups
Mar!o
I mean who is writing a business application or a simple app in c++ there are more suitable languanes like C# or python
Dima
I did my own kinda reflection stuff to simplify my game engine UI editor
Dima
simply some hashmap with property names and callbacks
Mar!o
Ur also a game engine programmer?
Mar!o

Yeah thats a nice way Ive written a simple python script which then generates the data files for me - its really easy no need buildin reflection
Mar!o
And typeid is still there to our rescue ;)

So the operation will be done in which precedence?
C++17 added The right operand is sequenced before the left operand. to [expr.ass].
hence x is 30 and y is 21
you can see the change from C++14 to C++17 when using MSVC

May I know what this tool is?
Compiler Explorer (e.g. https://godbolt.org/z/VyM2f-) you can either use the official version or run it locally. It's really awesome

Thank you so much

Does anybody know when C++ 20 will be released - sprint, summer?
Mar!o
Or at least when it will be available in msvc and visual studio 2019

The C++20 standard is planned to be launched right after the next meeting, which takes place in 2020 (I think in march). After that, it's a question of time for the compilers to implement it. In MSVC there's already a big portion of C++20 implemented, but also in clang and gcc
Francisco
Just turn on the flag -std=c++2a in gcc and clang or /std:c++latest in MSVC and the you can use C++20 (what's been implemented so far)

I know but there are still missing many things :/
Chandradeep
Is there any time difference functions for C lang?
Chandradeep
Actually i want to find the difference of two times which are in string... And i dont want to use time.h time_t as i need to map the date also
Esha
A little

C++ is an extended version of C Only

But there are some advancements

There's missing things even from C++17 in gcc and clang, so be patient
Francisco
The only compiler supporting full C++17 (including the STL) is MSVC. gcc an clang are still missing little bits
Francisco
Which means that you shouldn't expect any compiler to support full C++20 until, at least, 2022 (being optimostic)

Wow okay I didn't knew that because I'm developing my games only for Windows. I see there are also benefits when I'm using a compiler from a big company like Microsoft.

Not really
MSVC has some bugs and lack of some optimizations, afaik
