This guy is legit, for some reason after using C++ for 4 years, i feel like i never learned the language enough

After pausing the video 3 times, and meditating I finally got it, thank you Cherno

Cherno, thanks for these videos. After taking a year off of coding after school to pursue something else, reviewing these topics from a real-world use-case standpoint makes them make a lot more sense as to what they are useful for compared to how we learned them in school. Yes, we learned them well in school, but it was rarely made clear as to what the expected usage of each topic should be. I now have a better understanding of when I should overload operators!

Love this channel, I wish I found it 5 years ago back in university

Boy thanks again. This series has been on loop in my home for 3 months. I have been needing to override the ostream and was wondering what to do... and == TY for showing those useful tips

Sometimes. you just go through so much information and you understand it but you don't really understand it. Then sometimes, you stop to think and apply what you just learnt and you really understand the concept and you feel like your brain just expanded a little. This is happening too frequently since I have started watching this series.

Just what i was interested in. Thanks for the great stuff

This series is FABULOUS Cherno! You've clarified all of my doubts, thank u buddy =D

So clear, so neat and so well explained.

Thank you! I had difficulties with this but you made it a lot clearer.

Learning this in my CS class kinda made me die inside. I was able to understand you much more easily, thank you!

I'm loving C++ and your series

Basically do a: Vector2& operator++() { return (*this)--; } Vector2& operator--() { return (*this)++; } And watch the world burn. Pity that it wouldn't work.

Taking my first programming class and this series has been really helpful. Thank you.

This is so much more clear now! thanks!

i got stuck with an assignment for school, also using a Vector2f class in c++, this video got me started :D thx, i appreciate the help

That was some fast talking.

man, I must seem crazy being alone and clapping after each amazing video, TXS

Bloody great video

Wonderful explanation! Truly truly wonderful explanation of a pretty tricky concept to get your head around initially. Now it all makes sense.

Me and the bois watching The Cherno and growing brain cells

By far my hardest C++ lesson, might have to review previous lessons

just love your lectures~!

Can the "

It was really an informative video.Thanks Cherno😀

can you create custom operators? for instance if i wanted to make a class that represented a polynomial function and i wanted a member function that took its derivative would I be able to make say d an operator or would I have to either use a preexisting operator (making it harder to read) or be stuck with just the function?

well done! I finally understand!

Cherno My bro your one of the best teachers I've had and I didn't even pay you shit ! love your stuff man !!!

that's really cool!

Man, you are amazing, thank you a lot for your videos.

Thank you that's exactly what I need. our instructor is just telling us non senses in school

At 5:57 (and later at 11:09), is it okay to have a method call another one instead of doing the job itself in terms of performance? Is the assembly code exactly the same or?

Nice vidoes, probably best on youtube! I have a question: can i write my own oparetors, for example, operator === instead of overloading native == ?

thank you for sharing your knowledge

i'm working on a matrix library that works off of contiguous memory, so the basic way of accessing an element is Matrix[ columns*i + j ]; how can I implement operator overloading of [] such that I can still access it like Matrix[ i ][ j ]?

how bout operator[] ? not sure how that works

you literally saved my life!

At [ 5:57 ] you may have noticed he used the *operator* along with the *function* for the addition (which is defined just above that code by the way). Many of you may have thought ... Hey, can it cause performance issues !? , or can lead to slightly lower performance, the answer is ... *Yes* , but it depends ... - If you're making a *specific program* (for yourself), then do make a *single operator* , not along with the function.. As, it is really unnecessary. - If you're designing your own *specific Library* , then do what *Cherno* did. It will increase the *Functionality* and the *Flexibility* of your Library class. _Long story short ... It all depends._

Hey, Cherno, I really enjoy your video. I try to practice your technique. However, " return *this + other; " not work for me. I compile it with gnu g++. Is there any thing I missed?

For equal operator, do we need to define an errorThreshold epislon and compare two Vector difference with that epislon? Otherwise, the comparison result may be inaccurate.

I love how he gets tired of all the card thing lul

Is it possible to overload

Cherno deserves a medal!

I implemented leftshift operator as I said but gave an error like "ISO C++ forbids declaration of 'stream' with no type". What should I do instead?

At 7:32 will line 40 know to multiply first and then add? Does overriding the + and * symbol keep the order of operations?

Never fails to amaze me!

I am trying to make an operator oveload to insert the class atributes into a std::vector; but im really lost can someone send me on the right path?

Are your eyes really that color, it's cool man !

Do operator precedence rules remain the same upon being overridden, unless stated otherwise?

Just jump back to say thank you & clicked the thumbs up button for this video. Is there anyone like me have the same feeling: See your tutorial save me to click "x1.5" or "x2" botton.

"I left out operator overloading (in java) as a fairly personal choice because I had seen too many people abuse it in C++. " James Gosling

Hey Cherno, at 9:17 , why did we say that stream

I had to pause the video in the middle to like and subscribe because it's worth it.

Thank you for share!

your channels the best c++ tutorials on you tube without a doubt but man c++ is soooo much harder than python or php my brain is literally frying listening to you

So the operator overloads only apply to things done with Vector2 but nothing else? And what's this "other" thing he keeps passing? I don't see any passing going on but his functions have parameters. Does thing1 become the "other" that is passed in something like: thing1 + thing2 ?

I wish my brain would move as fast as you type

Can you ID an IDE that would highlight overloaded operators, such as color coding. It does make easier to read the code.

Why the output stream operator overloading function must be declared outside the struct scope ? why couldn't we declare it inside the struct ?

After the end of this series and the covering C++, can we get tutorials on a framework such as SDL or OpenGL? Or maybe something insanely new like Vulkan

very informative thank you a lot

I have to ask, what is the meaning when you write " :x(x), y(y) {} before the body of a function? is it a faster way to declare the variables?

I just did the calculation on the PowerUp Vector and the Speed Vector, and it turns out that PowerUp is actually slower!

working on a g++, c++11

Say I'd wanted to implement an operation like vector/scalar multiplication, e.g. Vec2 v(2.0f, 2.0f); float s = 2.0f; Vec2 result = v * s; Since this is a commutative operation I'd like to also be able to define a result for s * v, with the float coming before the Vec2. This can't be done inside the class definition because it will just assume the left side of the operator to be the object itself. I know the operator for the other order can just be defined outside of the class, like: struct Vec2 { float x, y; Vec2(float x, float y); Vec2 operator*(float s) const; }; Vec2 operator*(float s, const Vec2& v); but this seems a bit messy. Are there any conventions/other solutions for this? Also, sorry for the wall of text ^~^

06:43 He made the 'this' video, but didnt get to adding the link/card yet found here: kzfaq.info/get/bejne/kMWYg62Qqs7HlX0.html

If it helps from a python view, think of these operator overloading methods as deprecated methods from python (such as def __str__ and def __add__).

Can someone please explain why in the return you can write: return Vector2(.....); and not: return new Vector2(...); isn't the Vector2, that's created in the function gets destructed immediately? THANKS!

The best part is Cherno is criticizing the Boost.Serialization Library xD

if you don't overwrite the equals method in java, it will do == and basically check if the are stored at the same memory location. is that the same in c++ when you don't overwrite the == operator, or won't it even work because you have to overwrite the operator ?

very challenging stuff to understand. wow.

0:36 Actually,

some powerful stuff, really.

lol @ the boost reference

So sick.

"What are you doing" *stares hard* LOL😆

tysm very useful

//I write outside Vector2 like below without overloading the operator

I got so confused when I saw std::string. 🤣 This vid really saved me! Thx for the content!

If people need to go to the definition of your operator to understand what it does, you're probably not doing your job. Great video, Cherno!

Love u!

this video isnt for beginners.

Why do we need to create an overload for

11:00 I believe the compiler is able to auto generate the operator!= if you opverload the operator==, so you don't need to define your own, since the compiler just will negate the other operator you have defined.

What software is this???

Nice one, Your T-shirt , that painting in the wall , your eyes all have the same hue of green Is it coincident or planned :P

Wouldn't having operator!=(...) return x != other.x || y != other.y be more efficient (since you don't have to check 'y' if 'x' already failed the comparison).

You missed the bool operator :)

I'd be interested in a video about move assignment, copy assignment, assign by reference operators.

blows my mind

How do u not make this into a recursive overload at 09:10?

Can we do overloading on member functions for classes that contain more than one variable ?? if so is the case then what should the operator compare and how .

I haven't understood this for a year, and this guy explains it in 7 minutes *_wow_*

3:40 could someone explain why he wrote the constructor lines 8 and 9 like that and not like Vector2(float x, float y){ x(x); y(y); }

Binge watching these before my data structure c++ based class in Uni

following what you said about having operators be relevant, I have a really tough one. In electronics, the parallel impedance of some components is calculated by taking the inverse of the sum of the inverse impedances... like 1 / ((1 / z1) + (1 / z2)). In electrical engineering, it is commonplace to express this function with the || operator. do you think I would be out of line to overload that functionality into that operator?

awesome
