I'm not talking about not using c++ vectors and strings, in general it's a bad idea.

You have C in a core and a bunch of features from c++ bulit upon in the 20-year range. You're free to choose what feautures you do and do not like to use. Noone use 100% of c++

I am talking about teaching. It is more healthy to teach C++ way of doing things before teaching the C way so that they actually memorize the C++ way

C-strings being better? Make me laugh in strlen

Fixed message, I'm against c-strings in c++

I think it is better to understand internals if you use something

Oh yeah, but there is not only that. You don't want your new C++ devs to use qsort, printf, sprintf, and most of that stuff when writing C++ or handling raw pointers everywhere a unique_ptr would have been what they wanted

You can't write c++ and don't deal with pointers and memory stuff, it will pop out here and there. Better know how to work with it

Hi guys.. can anyonce here tell me easy guide to c++ STL? I am comfortable with c

STL died in 2003, what you mean is standard library

Proof?

Is that they use is competitive coding? Then that😅 i knw the basic syntax of c++ bt can't understand / read any solution from them

Video guides then

I'm not good in teaching. I think there're different ways to teach and a lot depends on the teacher.

Video guides then

Anything on mind?

Proof?

Is there any good book for c?

No, it is just that the STL was a thing written in 1994 that was later pushed into the C++ standard library

Let now not use linux and use gnu/linux instead. Who cares?

Let now not use linux and use gnu/linux instead. Who cares?

Well you are free to use GNU or not, I personally am slowly removing it so...

You can use Linux with pretty much any posix OS

I think that you can run most of openbsd's os on Linux if you remove pledge calls

WHAT are ostream and istream in c++ and how are these related to << and >> operators and what is cin and cout?

I don't want to flood about linux, I just mention it's a terminology problem

Can anyone help?

I don't want to flood about linux, I just mention it's a terminology problem

Well you can still use the literal SGI STL if you want to live in pain

No, it is just that the STL was a thing written in 1994 that was later pushed into the C++ standard library

They plz guide to learn that🙏

I advise you to read the documentation then tell us what you did not understand

What you want to learn is the Standard library, but I advise that if you know C, you learn C++ first

I learned it & can do programs with it. But when it comes to competitive coding... the solution/tutorials does nt make sense syntx wise :(

I think pic is better, arg says nothing

don't forget return a string :)

I read that the overloaded operator>>() is a member function of istream. So what is >> alone without operator written before it?

Send an example of it please

The operator⸮

all vars must be named what they mean

Why you need another var for arg?

it's a good sign of programming

use some prefix or postfix

Send an example of it please

Foe example is (vector) (forgive the brackets i am hsing ph) in c++ or c++ SL

I don't understand

for param mb some "p_num"

The operator⸮

What does that mean?

https://www.reddit.com/r/cpp/comments/cfk9de/201907_cologne_iso_c_committee_trip_report_the/

Interesting

What does that mean?

operator "?"

operator "?"

what

What does that mean?

it means like operator "if"

I read that the overloaded operator>>() is a member function of istream. So what is >> alone without operator written before it?

Right-shift from C

how is >> related with the istream class?

You already answered. It's a member funciton of istream

how is >> related with the istream class?

this->number = number;

I think you forgot 'this'

it’s a keyword

const ptr for ur object

This is address of class instance

it’s a keyword

or it's not const ? don't remember

const ptr for ur object

Not necessarily const

Depends on how object was created

It is T* const probably

You should learn, not hear

What's the book?

This technically works, because of variable shadowing (if you enable -Wshadow on gcc/cfe you'd see a warning), but better not do it, because it's confusing when the class is big

It is T* const probably

And if object is const itself, then T const * const

You could use an m_ prefix for member variables

That's a common practice with classes/structs

Yeah, qt creator gave him a warning as far as I can see

That's a common practice with classes/structs

I heard it's obsolete and not recommended

Compiler knows what's member of what

I heard it's obsolete and not recommended

Chromium uses it, for example

If that's obsolete, then what isn't?

Yes, but it simply starts to get confusing with a lot of member variables

Chromium uses it, for example

Chromium in many cases not checks malloc return, and what

Chromium uses it, for example

libstdc++ or libc++ use it. Don't remember which one, maybe both

And I've seen it in lots of places, so it's really common
