I've been struggling for weeks trying to understand this and pointers and you literally got it to click in 15mins. You're amazing, subscribed.

Crazy. I was reviewing this earlier! Keep it up!

Love your teaching method and your comedy sprinkled throughout! Thanks man!

this is awesome! thank you so much for creating these illuminating lectures !

This was incredibly helpful, thank you for the detailed explanations!

Thank you Caleb! I'm in a C++ bootcamp and your channel has taken me from failing to an A!

Wow, Caleb! Thank you so much for starting this series. I am in the middle of your first series of C++. That series is really awesome. I like your teaching style. You are a great teacher. I found you concluded the previous series a little short. I am delighted to see this intermediate series is started. Kindly continue this series. Your series is really helpful.

This was a wonderful video. I'll be patiently waiting for more.

the way you teach is very effective and easy to understand. Thank you!

Great explanation Caleb! Awesome. Way to go!

This is the first time any C++ concepts really started to "click". Bro, keep up the good work! Thank you for your help!

Nice, idk if you explained it really well or if after playing with references and coming back to an explanation was the final thing to make me understand this concept, but I feel like I finally get it.

this is great. Now I got it. My prof sucks. He mixed pointer and ref and totally confused us.

Great video! Exactly the explanation I was searching for

Thank you! This was well detailed and clear.

Wish I found this video sooner. After 4 hours of trying to understand this concept I finally get it haha. Thanks!

This was such a great video all sorts of confusion got cleared so well. Thanks brother.

Thank you for explaining the memory efficiency of references, I like to know why code is "best practise"

concise and clear. thanks dude

this video is actually fantastic, thank you so much, i appreciate your work, keep it up and good luck with everything :D

Thanks Caleb.you are an amazing teacher.

Thanks for the great explanation! I am new to C++ and needed to understand this, and also the part after 13:00 was very informative and useful!

You are a great instructor.

you explain things the best ive seen. thanks

I like the technique of your teaching. Really it's a great tutorial man

Love this video, he really does explain it far better than the course material in the 300 level undergrad course I'm currently taking. Also... LEEEEEEEEROYY JENNNNNNNNKINS

i am in love with your teaching style.

Nice! Thank you for this.

Bravo! Thank you.

Bro. You're a beast. This is just what I was looking for.

10:35 troll joke made me chuckle out loud, great video!

Very well explained!

just perfect ! thank you!!

Thanks man. You helped me a lot.

Thank you for this very useful video!

This can't be explained better than this. Top notch

Good tutorial. Thanks.

Best caleb in the world 👍❤️

Great video, thank you man

Thank you so much ✨

so far the best explonation i could find

Great video!!!

your r great... such a simple and clear explantion /////

Thank you well explained

Thank you very much. God bless!!!

Thanks caleb 💛

I love the way that you write & diffrent in every time😂😂

This is awesome !

At 13:30, what if you did like &b = &c? Would that work or can you only assign b directly and not it's address?

Nice video. I like how you dont write any code on a computer. makes it better

QUESTION: 7:58 to 8:04....doesn't "int &x" at the function refer to the 'address' of 'a' rather than the 'value ' of a ( ie '5')? That is, when we call the function, aren't we passing in the "address of a" rather than the "value of a"?

@masheroz

How I think of it working is: when you call work(a), internally the program is saying int & x = a; and then doing the things on x. I need to retrain my brain on how the function arguments work from my Java days, but the 'int' is always correct, and says that the function expects an integer. If it is 'int & x', it will get a reference to an integer, and if it is 'int * x' it will get a pointer to an integer.

Thanks for the tips

Thanks a lot!

I got problems but I had problems with understanding reference. It seems to me like reference is sometimes treated as a memory address but then you can also treat them as normal variables. When it comes to pointers it is clear when that you always have a memory adress and if you want to see what is on that memory address, or change what is on that memory address, you deference the pointer by putting a * in front of the pointer. These references are a little bit confusing because they sometimes act as pointers and they sometimes act as normal variables. I don't see why I can't just replace references with pointers. For instance the function swap would go like this. void swap(int* a, int* b) { int temp = *a; *a = *b; *b = temp; } Also, when you use pointers as arguments of a function you know you are passing memory addresses to the function so you expect that the function might change the variables whose addresses you are passing. I find pointers more clear and understandable than references.

Few basic examples to remember: void work (x){return x;} // No reference void work (&x){return x;} // Argument reference void& work (x){return x;} // Function reference void& work (&x){return x;} // Argument + Function reference int& a=b; reference variable to variables int&& ref=work(x); reference from function (without reference) to variable int& ref=work(x); reference from function (with reference) to variable

Just finished the last series and I really hope this is the start of part 2

After watching this video I have two things to say: 1 - thank you, your explanation is heaven sent and 2 - after your Leeroy Jenkins comment, I gotta ask. You play WoW, because if you do were gaming 😂

Young and Intelligent Your the best teacher Caleb. From Ethiopia

exactly what i looking for!

Helped some what keep it up

Well explained

"But no... you just got trolled" I almost spit my coffee

Dude you are on fire today.

"Maybe that's a bit more depth than you need for this introductory video" Nope. Not for me, at least. That last detail you went over was super helpful. Thank you for the great video!

Thanks Caleb

Subscribed! 🙂

how can we use pointer to reference like this (int *& a)

thank you for this

Your the best bro

You make learning this like 10 times more fun, i apprecieate it!

This is a great video and I understand references and pointers now (from your other video). However, I could change the variables that were passed in as parameters even without references. For example (in C++ still because I've been learning for 2 days so far lol): void Swap(int x, int y) { int temp = x x = y y = temp } And that works fine so 🤷

its not the same as he said in this case x and y would be a copy of the values you passed, the variables outside the fuction will still be the same even if you change the values in x and y

@@flyingspaghettimonster8612 Oh ok thank you, would I need to create a reference inside the function then and then change the value of that reference? That's pretty cool

I love this 😇😃omg so useful

I hate this dude when i was noob but still want to see this dude

this is mean, reference is not a new variable refer to specific place in memory? it is the variable which it refer to??!! so this is not add on size of memory one place! right?

IS THE USE OF "&" SAME AS WHEN YOU USE IT I EXCEL?

there is no love it button, so i will type. Love it, thanks a lot.

Hey can you make something on typescript

perfect!

12:05, I still don't get it, what if i just write "void swap (x,y)" in the first line ? btw, ur vid is just so clear, i can understand most of it quite ezly, i just dont get the idea of benefit when using it and the question above, why should i assign reference to a var when i can just call it directly ? Thank you :))

Hi, I may not be the best person to answer but I'm gonna try... So, if x and y are global variables then you can easily do that, but if the function is separated from the variables and they are not global then you need to pass them through parameters, that's where the references come handy because you can actually change the variable itself and not just make a copy when you call the function. Hope this helps

@@jennims2885 so ur idea is if i pass (int &x) what happen inside the func will change x actually, and if i pass (int x) , func will only use x for calculate and after the func is called, x return to its before func calling value ?

@jennims2885

@@-kindredeternalhunter9907 yes, the function just makes a copy of the variable to use it inside the function, it will not change the variable itself; once the function ends, the copy gets erased. So for example, if you want to make a void function that can't return anything you will not be able to change the variable itself, the only way to do so is by using references.
