I figured you'd have to use public access for much of the classes - otherwise I'd be making int main() a friend along with making the classes friends of each other, and even then I'd get an error with == operator being private due to a context of some sort of access inability in a template in a file called 'list.tcc'. I'm guessing my approach of not using public access at all would have been impossible?
You are so amazing with this stuff, Saldina. I just completed my C++ for Engineers and Scientists class and nailed a 95.6% for the class. I owe at least part of that to your great videos. And now that I know classes, I can understand this topic which he never did in my class. Thank you!!!! 😀
I have watched three different videos of friend functions on UA-cam and you are absolutely the best. You explains in details why we need to use friend functions and when to use them. I subscribed you and will keep watch your videos! You're very talented teaching c++.
When you finish making all the beginner videos, you should make some videos about Qt 6. It's more advanced and _way_ more capable, and it's relatively easy to use. Personally I love programming with Qt, since it just lets you do everything your way and it has a very deep connection with C++ (they "invented" a lot of the things in stdlib today like smart pointers etc...). I particularly find the concept of signals and slots amazing for multi-threaded programs. While it is mostly used to make GUI apps, you can also just make CLI programs that work really well. If you don't know anything about qt, then make it your new years resolution to learn it. I guarantee you won't regret it. Sretna nova godina!
Thanks a lot for those awesome videos!! I used to learn C++ and it was too hard for me so I gave up. After watching your tutorials, your excellent and outstanding work has given me confidence in learning C++ and interest in programming again. You are an excellent teacher and a role model for me on the way to learning code. Now I think the code is really cool, I also hope to become a programmer one day. Thank you again for everything.
Hi, thank you for your outstanding videos. Very helpful and refreshing. In C++, a function can be designated as a friend of a class, allowing it to access the private and protected members of that class. This friendship can be established in three ways: a stand-alone function, a member function of another class, and a separate class. In your last example, you mentioned that a member function of another class cannot be declared as a friend. To clarify, it is indeed possible to declare a member function of another class as a friend. What was likely meant is that a member function of a class cannot be declared as a friend of the same class it belongs to. In the context of friend functions, the typical scenario is to declare a stand-alone function or a member function of another class as a friend of a class, enabling it to access the private and protected members of that class. If you need to provide friend access specifically for a member function of another class, you can achieve this by declaring the entire class as a friend, not just the individual member function. Would you please clarify?, thank you.
Another way, to have firend function, #include using namespace std; class Base; class BaseFriend { public: void printResult(Base& b); }; class Base { private: float a; float power = 0; public: void setA(float l) { a = l; power = a * a; } friend void BaseFriend::printResult(Base&); }; void BaseFriend::printResult(Base& b) { cout

you said creating getters is not a good solution because, everyone would be able to excess the class variables using getters, but the same thing is true for a friend function also, everyone can still access them now using friend function.
Thank you so much for the videos. They are very helpful. The way you are explaining from basic level followed by intermediate level is very helpful. Also, please make the videos on advanced concepts and incorporating security measures (like buffer overflow) in C++ code. Also, kindly post videos very frequently.
Hi Saldina first of all, your videos are great and well explained, question, what is the differences between friends class and Inheritance what are the benefits of using friends over Inheritance?
I am studying c++ for months and i couldnt understand anything and i was afraid of my midterm exam but i feel like i am starting to understand so thank you so much (ps: your diction is very good so i can understand easily even though i am not native in English and also you speak sincerely so I don't start daydreaming in class and I listen carefully :) . Thanks again)
The reason the PrintResults function won't work is because you made it a member of the Homework class. So to access it you would have to use to dot operator after making an object of the homework class.
Share it with your friends, but she told us to be careful to choose friends and friends don't inherit and friendship isn't mutual, so basically now I haven't friends to share it. 😔
Hi, Saldina! good morning according to Afghanistan Time Zone. thanks a lot from this lecture also i was a little bit worry about you because you wasn't present on your social media.so I wish from GOD to help you what something wrong happened with you to solve As soon As possible.
Dear Saldina, i am trying to find in your channel a video of getter and setter but i can't find it anywhere.If you made a video explaining them can you please send me the link ? Have a nice day ! And thank you for your videos i understand everything you say and it's very helpful :)
C++ friend is just something not in the human world. Its advanced uses are far too complex! For example you have to friend the outer class before friend-ing the inside class if it is declared in private or protected field of the outer class, you cant friend other class's member function before the class is define, you have to let class A friend class B in order to let B friend a private member function of A! That was just a few😅

Can you please post a full detailed long video on below two topics:
Data structures using C++
STL using C++
Finally found the ultimate teacher...
So concrete and so useful. You're the best...
You made my preparation for the exam easier and less stressful. Thank you for the good work!
I come to your channel everyday to learn something new. Thanks!
I'm happy to hear that, cheers 🥰🥰

One of the most clear explaination of Friend function on the internet.

I'm in love with this channel, and even if I'm not fluent in english I can understand you pretty clearly.
she cleared the concept very clearly, good work
thank you so much, I watched 1000+ videos and they never explain everything in so much detail!!!

Hey Saldina, your lessons are greatt 😁. And one thing, I guess it's called perimeter, circumference is perimeter of circle...
You are the best teacher ever. Thanks for reminding me how beautiful programming is. *_*
Another way, to have firend function,
#include
using namespace std;
class Base;
class BaseFriend {
public:
void printResult(Base& b);
};
class Base {
private:
float a;
float power = 0;
public:
void setA(float l) {
a = l;
power = a * a;
}
friend void BaseFriend::printResult(Base&);
};
void BaseFriend::printResult(Base& b) {
cout
God bless you, Saldina! You are so good at explaining these concepts.

mam its my first time to watch your video .
your explanation is great, thank you for this type of useful videos
love from INDIA
Awesome stuff, thank you for helping me brush up on my OOP skills.
Wow, I love how you can make a topic seem so simple and easy to understand!!! Love it!
🥰🥰
Imas svoj stil, objasnjavas jasno i detaljno. Puno truda ulazes u svaki video i to se vidi. Hvala jos jednom.
:)
Saldina how about a code review series? We would love to send you our C++ projects 🙂 and would love your reaction on it.
you said creating getters is not a good solution because, everyone would be able to excess the class variables using getters, but the same thing is true for a friend function also, everyone can still access them now using friend function.
❤ Really Appreciate the efforts... Explained a lot of better than teaching in my university.
I finally understand them...thanks!
Hi Saldina, Can you please make a video on using friend classes with a forward declaration for the Google test without altering the source code?
Hey, waiting for the premiere ,lots of appreciation and thanks for teaching us.
we have not called PrintResults function yet, and walso we have to pass the et object as the parameter... God bless you!
Great Job! I learnt alot today, and I am grateful.🙂
I choose to stay not only because you're amusing (haha) also because you explain the concepts very well, step by step and logically.
great video , love from South Africa
You need to use this pointer when setting the length in setA function . It is a good practice!
I ready do admire your teaching always
You’re quite amazing 😻 .
Thank You! You explained it way better than how my book tried to! 👍👍👍

Hi Saldina first of all, your videos are great and well explained, question, what is the differences between friends class and Inheritance what are the benefits of using friends over Inheritance?
Excellent explanation, ty so much!
Could you please make a video about when we should use "const", and when should we pass by const reference or by value.. Thank you!
Wow so nice I completed Your OOP C++ video and I was about to learn friend function and your uploading a video so nice thank you Ma'am
I am studying c++ for months and i couldnt understand anything and i was afraid of my midterm exam but i feel like i am starting to understand so thank you so much (ps: your diction is very good so i can understand easily even though i am not native in English and also you speak sincerely so I don't start daydreaming in class and I listen carefully :) .

Please view Bro Code videos too. It's very detail course with real examples.
Thanks alot for these kinda outstanding videos, it means alot to me (student)
The reason the PrintResults function won't work is because you made it a member of the Homework class. So to access it you would have to use to dot operator after making an object of the homework class.
Instead of circumference it's called perimeter! Great videos thanks 👍
Hello, thank you for this great job. Could you please do a tutorial about modern C++ (like C++11 and more). Thank you in advance ☺️
Wholesome programming content indeed 😊
thank you for updating to dark mode
Really very instructive lecture !
Thank you
You used a Brazilian meme hahaha. I'm from Brazil. Excellent content, thank you.
// friend functions
// #include
// using namespace std;
// class Triangle{
// private:
// int side_length, circum;
// public:
// void set_side(int a){
// side_length=a;
// circum=side_length*3;
// }
// friend void PrintResults(Triangle); //no need to specify parameter name....parameter type is enough
// };
// void PrintResults(Triangle obj){
// cout
9:40 - You forgot to call the function :D
Hello from Philippines!
your lessons are great
thank you, very helpful!
incredible work!
I am happy to see that i am not the only one who forget basic mathametics while i am wriing some code. 😁😁
oh it happens to me on daily basis :)
Share it with your friends, but she told us to be careful to choose friends and friends don't inherit and friendship isn't mutual, so basically now I haven't friends to share it. 😔
excellent video, the humour was also good.
Thou shall not fall in love with your teacher 😭😭😭😭
something similar ....... coincidence do happen wow.......
disgusting
Victor are you saying you're gay?
Simp init
Nah u down bad
Merry chrismas and happy new year.
The results from a calculator and this program for the area is different. Quite similar, yet big gap. Why is that? How is float rounding?
ngl i never comment but your actually really good at explaining
Hi, Saldina! good morning according to Afghanistan Time Zone. thanks a lot from this lecture also i was a little bit worry about you because you wasn't present on your social media.so I wish from GOD to help you what something wrong happened with you to solve As soon As possible.
Thankyou saldina.
what keyboard you are using, sounds fantastic
Suspenseful stuff...absolutely blindsided by the area of triangle formula 🤣
best teacher😻🙂
Dear Saldina, i am trying to find in your channel a video of getter and setter but i can't find it anywhere.If you made a video explaining them can you please send me the link ? Have a nice day ! And thank you for your videos i understand everything you say and it's very helpful :)
those are parts of Encapsulation, here are videos for both C++ and C#
ua-cam.com/video/vQ6k1U6nADY/v-deo.html
ua-cam.com/video/a8ZB-TPB6EU/v-deo.html
@@CodeBeauty thank you !!!!
Have a nice day :)
a problem with using friend functions is that they are not as optimizable or as self documenting as comprehensive getters & setters.
excelent . thanks . i download all your videos. thanks
Would it be possible to post .txt with your UA-cam videos, it would be easier to follow along?
you are just awesome😇 I love the way you teach😄👌
thanks so much❤
What is the advantage of friend function over friend classes ???
Hey!
Is it a good idea to pass a parameter to the friend function by the constant reference?
I love your contant and your stille in explain
u are a legend istg
Can we access a friend function, friend member function and friend class in a same program?
awesome! thanks for share!
Please, could you explain a data structure type that is called a graph or tree Thank you very much
Would you like me to link you some resources I've found helpful?
Amazing ve beneficial videos, thanks ...
Good job, thanks 👍
4:10 I watched that part like 5 times... so cute haha
I actually did stay because you are extremely amusing 😂
Mam, I want to develop an application for laptop functionality testing. I am new to c++, which tool I can use
mam plzzzzzzzzzzzz 🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽 make video on aggregation and composition in C++
Great mam.
Where are you from
thank u very much princess
I thought about it carefully and I want you to be my friend.
04:15 Fun fact, this meme isn't Julia Roberts
C++ friend is just something not in the human world. Its advanced uses are far too complex!

That was just a few😅
You’re amazing 🤩🤩🤩🤩🤩
now printresult is not a global function
that's why it give error
Thank you
3:00 perimeter not circumference
great content!
Nice work
THANKS!!!
you are the best
I saw friend classes used very badly in 3dsmax years ago. So I am not a fan of this C++ feature. C# got rid of the feature btw.
