Homework solution: #include #include #include using namespace std; class RU-vidChannel { string Name; int SubscribersCount; public: RU-vidChannel(string name, int subscribersCount) { Name = name; SubscribersCount = subscribersCount; } bool operator==(const RU-vidChannel& channel) const { return this->Name == channel.Name; } friend ostream& operator
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 RU-vid 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++.
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.
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!
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.
currently I'm focused more on teaching C# because there is higher demand for C# developers, so you might wanna check my Practical Programming Course at www.codebeautyacademy.com We are building real C# application and you will be learning alongside other students, with me as your personal tutor. With this you will also gain access to exclusive Discord community. I'll be happy to have you there. :)
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
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.
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.
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.
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.
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. 😔
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# ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vQ6k1U6nADY.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-a8ZB-TPB6EU.html
