Yes, you can

Putting this-> everywhere decreases code's readability

Remember what using initialise list is always better
I_Interface
Better code optimization for compiler

Just believe😂
It's a good practice
I_Interface
And if u are using const it will be more faster
I_Interface
If u using constexpr it will be more faster

const can be faster?

It's not important for him right now

Watch cppcon video from Jason Turner about Practical participate

Of course you didn't
It can be noticable in high performance applications mostly
You can play around with it and look the generated assembly code

My only experience with assembly code is on 51 series MCU lol

Consider you have a class with such constructor:
Class(int x);
And you have a function:
void func(Class arg);
Anonymous
Then you call the function
func(5);
Anonymous
This code is correct
Anonymous
But the func doesn't take an int as a parameter, right?
Anonymous
So compiler looks at the list of constructors of the Class
And it like "well, i can construct a Class object from an int, so it's a valid function call"
Anonymous
Sometimes it's an appropriate behavior, sometimes it's not
Anonymous
The explicit keyword tells compiler that it cannot create an object of a class implicitly
Anonymous
If a Class has such a constructor:
explicit Class(int x);
Anonymous
It's not a valid func call anymore
To make it valid, you should explicitly tell the compiler
func(Class(5));
Anonymous
Because we declared such a constructor

Well, what programming experience do you have?
Anonymous
Well
Anonymous
You're on the wrong way, my friend

Because classes should not be the first topic in anyone's programming learning path

You should start with a book called "C++ Primer Plus" by Stephen Prata
I_Interface
It's a wrong book

It's a better option

What is the book, again? And the author?

@IWASFRAMED, got it?

I started with Herbert Schild C++. Also is good
I_Interface
Why?
I_Interface
Idk why he don't like it, but it was a good book for me as for beginner

Just believe me

I don't does it suck or not

But if the first chapter is about classes

There's something wrong

Ok?

I don't like it

I don't like how the info is structured
Anonymous
It should not be in that order
Anonymous
So it officially sucks

Just take the Prata's book and be happy
Anonymous
It's recommend by good c++ developers
Anonymous
Simple projects and another, more advanced, book
Stephanos
After the First book i guess you should start watching talks
Stephanos
In YouTube or at conferences
Anonymous

Yeah, it's a good learning resource too
Stephanos
And Always Look Up Terms one doesnt know on cppreference or stackoverflow
Anonymous
But it's harder to know which talk you should watch
Stephanos
I guess getting a Mentor is the best Thing
Stephanos
But getting the right one is also really hard
Anonymous
But it's harder to know which talk you should watch
Because most of the talks are on advanced topics
Stephanos
Because you never know whos a jerk
Anonymous
I can recommend Kate Gregory's talks
Anonymous
So start Prata, try some things by yourself
Try to build your own programs
Google what you don't understand
Anonymous
It's too early for you to watch talks
Anonymous
Learn basics first
Anonymous
Then you can try to start Qt
Anonymous
And other things

Use Prata, ok?

Hi. Does anyone here know about basic programming language?
