In this video we will learn "Stream Insertion And Stream Extraction Operator Overloading" in c++ programming language.
There are few points to remember is as follows:
1. When we need overload these operators?
2. It can't be class member function (reason we will discuss), you have to make it friend function of your class.
You will get to know why we need to overload these operators in c++.

God bless you.. I just learned so much for free than from a book I bought for 50 dollars..

[@CppNuts]

Thanks man!!

[@khalidaaliyeva2250]

"" is stream extraction operator. The left-hand operand of this operator must be an istream object. Again, the direction of the arrows indicates that we read from the stream. We extract from the stream.

[@maheiramkhan]

Thanks.

[@moonwalkingdancer8369]

hey hold on why do we use referances in ostream&operatror

[@heybuddy_JAI_SHREE_RAM]

this explanation just blow my mind 🤯🤯u have got a new subsciber

[@CppNuts]

Thanks man..

[@AkhileshSingh-y4v]

I have a question: At 6:35 timestamp, you said that if the data members which we are using for '' operation are if public then we don't need to use friend keyword. my problem: I tried to overload the function in a template of struct but i wasn't able to do it without making the overloaded function as a friend function. But all the members of struct are public by default then why I have to make that overloaded function as friend function. (All the declarations are inside the struct template). Please help me in this.

[@pushkarkumarsharma3256]

Sir, I don't understand if we return input, output but where we receive it . In the example P1=P2+ P3 here we return and store it into P1 but in this example input and output return but where we receive it this thing I don't understand.

[@buidu691]

i don't really understand line 22,return input statement just is cin copy ,Do i think right ? Pls explain for me.Tks a lot

You are welcome..

[@Turkish_Microwave]

thanks man this really helped me out !

[@hassankamran3480]

How are you calling private data members just by objects? Shouldn't we be using getter function instead?

[@syedatifshah8020]

Full of information...i am very pleased sir .may allah bless you

[@CppNuts]

Thanks

[@maheiramkhan]

This was very helpful. Thankyou, sir.

[@CppNuts]

Welcome!!

[@surajnaik4645]

Test(int x=0) :x{x} {},can u tell me what does this line do and what does x{x} do?

[@CppNuts]

It initialise x into x.

[@Chopperaemon]

line number 15: Test(int x=0):x{x} {} what does that x{x} does in this statement and why is there an empty bracket??

[@Sindujaify]

This is called initializer list in c++. It is similar to x = x where first x is member variable and 2nd x is passed parameter and {} is just a place holder

[@rudrapratap3303]

wonderful explanation!

[@CppNuts]

Thanks..

[@seizondhakal1047]

What a valuable video!! Thank you..

[@ArjunArjun-vw5fq]

friend why we assign constructor with default arguments like cons_name(int x=0):x{ }{} why we are assigning x=0??

[@CSSuccessGamer]

Thanks for the video! Do you have tutorial for creating binary tree class and overloading it to print out the root and left or right nodes? And for adding in new stuff to the tree?

[@CppNuts]

After completing threading and STL topic i will start DS and AL.

[@kkgt6591]

Nicely explained.

[@CppNuts]

Thank you so much!!

[@cid007007]

int main() { Base b(10); Test t(30); cout

[@CppNuts]

Here is the link i wrote it for you: coliru.stacked-crooked.com/a/68ef59b37d05fd9d let me know if you still have some doubts.

[@cid007007]

@@CppNuts Thanks alot working : #include using namespace std; class Base { int x; public: Base(int x=0):x{x} {} friend class Test; }; class Test { int x; public: Test(int x=0):x{x}{} int operator + (Base& b) { return x+b.x; } }; int main() { Base b(10); Test t(20); cout

[@CppNuts]

Good..

[@akanshmishra7302]

can you explain once again why we are returning by reference? Where are we returning actually? Sorry, I didn't understand that part.

[@Ch_abdullah00]

Well explained ❤️

[@nithyanarayan8080]

Very nice video. So If I want to do it for more than one class, how will I pass my object as second parameter to overloaded functions? Can you please help me here?

[@mikelai7483]

why we need to put ostream & operator

[@JohnWickXD]

Nope bro...Without returning reference, it will returned as a value...but we want to use it again as a cin object....

[@ThatManAcid]

thanks this actually helped out a lot good explination

[@CppNuts]

Thanks man!!

[@avikmallick2493]

Sir in 11:21 I didn't understand how the cin>>t is becoming cin and then it is reading t1.can u plz explain?

[@Sindujaify]

because the overloaded function return cin

[@stormbreaker9913]

Which IDE you are using??

[@CppNuts]

Sublime Text Editor 3

[@sakshams03]

Thanks for the wonderful video, can you please explain how to write overloading function inside the class, there it gives error because reference to class is implicitly present as this keyword.

[@fardinanamaungon8890]

What will I do if my class has more than one variables?

[@abhipsachatterjee5470]

Test(int x=0):x{x} {} in this expression what x{x} means? someone please reply
