Overview of this and previous video:- In previous video, we declared a function outside class and that function tried to access the members of class which is not possible. So we declared the function friend. In this video, we made 2 classes with their respective functions and the members/functions of one class tried to access the members of other class which is not possible. So we declared the members of one class the friend of other class or we can declare the whole class friend of other class. Rest is syntax which we need to understand.
@@anwesh07 'add' function is not trying to access the variables a & b in Complex class bcoz they have same name but they are stored in different memory location. Let us say if you have a class A with variable 'int a' in private & a function to set and display for 'a'. Now there is a function outside the class to display 'a' as well. In the parameter if you will write (int a) and {cout

You are very good teacher Maine aaj tak aapke jaisa koi teacher nahi dekha youtube par bhi aur kahi bhi Sachme aap ki padhane ki technic bahtreen hai 👌👌👌❤️❤️❤️❤️
@@artishsharma7859 Well as far as I could understand , he here declared calculator class before complex class which does not has a specific reason so if u do not wish to change the position of the class then u can do so but then u will have to Forward declare the Calculator class instead of Complex class, rest same.
Bhai main cheez thank u so much for zooming the program while typing ... Whenever the size is small it's difficult to see .. but next moment u zoom (ctrl +) it and u make everything easy , enjoyable and intresting ...❤️❤️❤️❤️👍👍🙏 Thank u so much
we can also do like-- (for checking greater number in 2 classes) class A{ int a; //here we have declared the function as a frind funtion friend check(int a,int b); public: void read(int val1){ a=val1; } }; class B{ int b; friend check(int a,int b); public: void read(int val2){ b=val2; } void check(int a, int b){ if(a>b){ cout
Nice video.But you didn't tell that why you placed calculator class above the complex class at time of error (at 5: 50). Because in stating we don't have to declare complex class at top and sum real function at bottom.And I got all points other than this and thanks for videos
By mistake he declared calculator class first,after that complex class. but in calculator class we have complex class as a datatype in one function which is not declared yet.So just declared complex class before calculator so that he doesn't get errors . Without re declaration you can just write calculator class after complex class.But sir explained alternative way if we don't want to change position of code. I guess 😀
It's because when declaring the friend functions, for scope resolution you obviously need to write thr name of the class calculator... And there the compiler will throw an error.. So it needs to be declared first.
I guess in class calculator We wrote int add(int a, int b){ return (a+b); is not really used to in program Also print function of class complex is not used . It can be used very well for smooth output and clearance. i wrote this comment after doing this lecture and practical experience. apologize if I'm wrong. My aim is not to provide any wrong info to anyone.
Of course programming is hard. It's definitely not an easy task. But you have to learn it every day without skipping a day and constantly grind yourself then you will understand little by little everyday. c++ is quite hard than other languages like python, javascript,etc. So don't give up yet.
9:21 हैरी की बातो से ऐसा लगता है जो फनी वे में बात करु तो , कोई आदमी, एक एक करके पकोड़े बनाने की रेसिपी बताता हो ,और बीच बीच में कहे की ये चीज याद रखो ,ये याद रखो ।जब हम पूछे की भाई पकोड़े की रेसिपी क्यू याद रखे हमे तो चाय बनानी है ,तो फिर वो कहेगा ,वो ठीक है लेकिन अभी ये पकोड़े की रेसिपी याद कर लो काम आयेगी।
see despite of just forwarding declaration of complex class above than calculator class . We select to define the complex class and then calculator class. In this way we have full definition of complex class so we can access it directly in calculator function. Isn't it??

Hey harry, I just wrote the code for making an entire class as a friend and that's the code below, kindly check it and suggest some improvements: code: #include using namespace std; // creating a class complex to handle the complex numbers class complex; // by forward slashing // creating a class calculator to handle the mathematical functions class calculator{ public: void sumcomplex(complex c1,complex c2); // by forward slashing }; // defining the complex class over here class complex{ int a,b; public: void setnumber(int x,int y); // making an entire class as a friend // all functions of the class calculator can now access the private data of the class complex friend class calculator; }; void complex :: setnumber(int x , int y){ a = x; b = y; cout

The course is very helpful especially for beginners, your way of explaining is very awesome and unique. I love this course.

we can also do like--

//here we have declared the function as a frind funtion
friend check(int a,int b);

It's because when declaring the friend functions, for scope resolution you obviously need to write thr name of the class calculator... And there the compiler will throw an error.. So it needs to be declared first.
because compile don't know what is sumrealcomplex, it we define calculator class below complex class it gives error
.

Just amazing, I am from westBengal👌👌👌
1st time it did'nt clear so much but after watching the lecture 2nd time , all clear good work harry bhai>

We wrote int add(int a, int b){
return (a+b);
is not really used to in program
Also print function of class complex is not used . It can be used very well for smooth output and clearance.

void sumcomplex(complex c1,complex c2); // by forward slashing

// defining the complex class over here
class complex{
int a,b;
public:
void setnumber(int x,int y);
// making an entire class as a friend
// all functions of the class calculator can now access the private data of the class complex

Why can't we keep the complex class before Calculator class and forward declare the calculator class ?
listen to the video once again and you will understand it. He has explained everything very nicely.
even we forward declared calculator class but yet the function we are making friend function in complex class is not declared yet
i have the same doubt
if it is cleared please enlighten me
