hey everyone , i want to ask a question about the value that return from a method of the class :
if i have a class , i can return a reference to the object that made? for example:
» class A {
int x;
int y;
default constructor()...
method for example :
*A &* foo(bla bla bla){}

Can you right code...
Because I doesn't understood what you want to explain...

*A & * foo() ? Doesn't make sense. You should share the whole code. Use pastebin or something though

Can anyone make a software to decompile a complied file
Blue
I’ll pay them

Can anyone make a software to decompile a complied file
You said same thing last time and you're trying to decode a coded file... that is not decompile.
Blue
It’s just encrypted file
Blue
It’s decompile, when I have a software that can make that file that is Known as complie
Blue
So reversed is decompile
Talula

No it's not, you want to decode an encoded form.
Talula
Forms are not "compiled" specially written by 3rd Party which doesn't make a compiler.
Blue
It’s not what u thinking
Talula
We talked and I know what you are talking about...
Blue
Nooo u are not understanding that
Blue
As u don’t know about the software which I am talking about ,
Talula
Your are talking about that accounting software Tel (something).

+= operator needs to be friend function?
Bumpy
why?
Ehsan
Lol

+= operator needs to be friend function?
There are two types of such operator, you can make it member function or free function. If it's a free function and your data is private, you need to declare is as a friend
hiddenpiggy
friend T operator+(T& a, T& b);
hiddenpiggy
T operator+(T &other);
hiddenpiggy
they are all the same

Hi, we have an embedded cpp group would you like to join? (saw your profile looks like you might be interested)

Boolean operators needs to be friends?

not exactly

its depends of?

If you need to access private members outside the class, you need a friend function. If you are inside the class, you don't need a friend method. It depends on the structure of the code

ok , so if i have a example.hpp file that's contains the declaration of the methods and functions ,
and also have a example.cpp file that's contains the implementation of this functions , i need to use friend keyword ?

thanks! . Does this also include the functions that are not necessarily Booleans? for example + , - and more

It's the same thing. They are operator just like the booleans one

thank u very much!

No one knows about QT more than you do.
That's not true

Hey guys. I have a question. Can you use static vector variables in a class to store values every time the program is ran?
Damo
While compiling make file..I'm getting some errors

The question is not very clear, what do you mean by "store values every time the program is ran"? You mean initialize them once?

For serialization you need to save values in a file of some sort. Depending on the circumstances, you might use anything between a text file(light ones such JSON, yaml, toml, csv) and a full fledged database(mariadb, mongodb).

Hi guys! Can you help me please?!
I want shift one column in array, but my experience and Google don't help me (
Example
Source array
1 2 3
4 5 6
7 8 9
Results array
1 _ 3
4 2 6
7 5 9
Where 8 will be deleted and _ is empty.
if you shared C example, i will be pleasure! thanks!

Hey , I want to calculate the CPU cycle per iteration .
So it should be
(Runtime of iterations*Clock_Freq_of_CPU)/( no of iterations * Total elements transfered in total loop )
Epem
But I am not able to calculate the no of elements transferred in the loop
Epem
For (I=0; i<slices;I++)
{
X=(I+0.5) *0.0006
Cout<<X;
Sum+=/////
}
Epem
How to calculate the total no of elements transit in the loop.

uhhh you're better off counting the assembly instructions by hand I'd say
Diego
I'm pretty sure each asm instruction is a single cycle if you don't account for threading
Diego
That is, if you don't use any system calls like cout
Epem
I'm pretty sure each asm instruction is a single cycle if you don't account for threading
But why would that be? It will take around 3-4 cycle / Instructions. I know the answer but how to approach It 😉

Why would it take 3 cycles for a single instruction though?
