Guys

✋✋✋✋✋

How are you doing

i'd love to eat more but i'm afraid of the walk to the fridge..............where are you?😢😢😢😢😢

i'd love to code more but i'm afraid to correct the code😑😑😑😑

Only one error: main.cpp:12:30: error: invalid use of incomplete type ‘class B’

the conpiler doesnt know what b looks like yet

it doesnt know that b has that function yet

welcome

then why it is working properly if i use

friend class B;

instead of friend void B::setdataofA(A&);

friend class B;

i already told you everything, do the thinking

could try enemy class B;

could try enemy class B;

What is Hardware independent and Platform independent? I will learn C programming

Think about what the word "hardware independent" says

lol

I sent it by mistake

I sent it by mistake

/warn sent pornographical content to the group

i'm sorry, but thats kinda severe

Yep

what kind of pornography did he send?

I am curious

Okay sir. I can understand. But what's Bot curl library? ...is it a bit channel in telegram?..

don't take it seriousely 😂

#include<iostream> using namespace std; class A; class B; class B { public: void showdataofA(A&); }; class A { int aa; public: void setdata(int aa) { this->aa=aa; } friend void B::showdataofA(A &a); }; void B::showdataofA(A &a) { cout<<a.aa; } int main() { A obja;B objb; obja.setdata(5); objb.showdataofA(obja); }

this code is working!

```

Сongratulation!

#include<iostream> using namespace std; class A; class B; class B { public: void showdataofA(A&); }; void B::showdataofA(A &a) { cout<<a.aa; } class A { int aa; public: void setdata(int aa) { this->aa=aa; } friend void B::showdataofA(A &a); }; int main() { A obja;B objb; obja.setdata(5); objb.showdataofA(obja); }

but this is not!!

i dont what is difference between them

they are the same?

can you point out the line where they differ?

i'm too lazy to parse them

only difference i found is defination of void B::showdatofA(A &a); is in different place

Roses are red.

only difference i found is defination of void B::showdatofA(A &a); is in different place

Oh I see

I see the difference, sorry

i don't see why one wouldn't compile

plzz try to compile both @linuxer4fun

why one is working and other not??

plzz help!!!

a is not a full type yet

the problem is not with your friend statement

it doesn't know what a.aa is yet

how could it?

ohk

public: int aa;

public: int aa;

I did this when I tried to fix this code, but class A has a friend function

In theory, it must work

Please help me in fixing this issue.

I have linked all required libraries but still I am getting this.

In theory, it must work

do your thinking

Please, try to press "prt sc sysrq" button

Pretty weird then 😯

Please, try to press "prt sc sysrq" button

perhaps, he has not got cinet connection

As you see, he has 🙂

good job!

I have linked all libraries required for glfw . My code was working fine on windows 10. But its not working in Linux.

windows uses DLLs

linu does not

windows uses DLLs

Yup that's pretty much it

so the linking is fundamentally different

Yes I compiled all files from source again in Linux using cmake

K

😭😭😭

Thanks

Well
