You can develop anything with C++
But it's not the best choice for everything

it is (at worst) a good choice for anything
Sasuke
An app is an application. I mean mobile apps. You can use cpp for other apps obv
Like creating android/ios application? Like Spotify?

So not really

Some agile softwares MUST not developed with C++!!

Agile softwares? They doesn't exist. Agile is not a software
BinaryByter
Lunatic is confused
BinaryByter
give him some time
Mihail
btw: how many bytes do you need for a "hello world"?
Eh that's not really a good comparasion
Mihail
It isn't

Okay, then lets stop discussing htis

Alright family, I feel like this is a beginner question.
What does int(*)(int) mean in a std::any_cast?
Raul
Basically I have an unordered_map<string,any> and I am trying to cast any to a function pointer.
Raul
So I have a function called:
int doMath(int a) return a+10;
Raul
Then I assign my map to an iterator and I do:
int result = std::any_cast<int(*)(int)>(iter->second)(10);
Raul
But I have 0 clue what int(*)(int) is doing. Anyone have any answers?
Carmine
Maybe it is a stupid question, but… why are you using function pointers and not lambda functions (std::function in <functional>)?
Raul
However I'll give you the issue:
Raul
std:: unordered_map<string, std::function<void()>>;
Raul
If I have a function:
void print()
{
std::cout << "Hi";
}
Then doing map["print"] = print;
Compiles happily!
Raul
However,
int doMath(int a)
And then:
map["doMath"] = doMath;
And boom! Compiler errors! Because:
std::function<void()> is not std::function<int(int)>
Carmine
However,
int doMath(int a)
And then:
map["doMath"] = doMath;
And boom! Compiler errors! Because:
std::function<void()> is not std::function<int(int)>
And a map of <string, std::function<int(int)>>?
Raul
And a map of <string, std::function<int(int)>>?
But I want 1 map. Not multiple maps.
Raul
That is the issue
Carmine
But I want 1 map. Not multiple maps.
You can use a void pointer, but casting every time in different types isn’t useful. IMHO you have to rethink your code
olli
But I have 0 clue what int(*)(int) is doing. Anyone have any answers?
int(*)(int) is the type of a function pointer taking one int argument and returning an int
Raul
int(*)(int) is the type of a function pointer taking one int argument and returning an int
Isn't this C-style casting?

How do i create an array of objects ?

Are there any binary reversing groups in TG?

I have a binary that is packed, and I am able to breakpoint to the poibt where it is unpacked, but I get an access violation exception
Jussi
I guess this is some sort of "anti-debugging" trick, but how could I patch it?
Jussi
The code I run BEFORE the breakpoint only XORs the other part of the binary, I dont see any "traps" against debugging

I have a contact class with name surname and telephone. I declare an object of contact class with the methods setSurname setName setTelephone. I create a contact using these methods
Magnvm_Khaos
If i want to create an agenda( many contacts together) how i can do it using an array?

It's better to use
std::array<contact, 10>
MᏫᎻᎯᎷᎷᎬᎠ
Unless you want a variable length
BinaryByter
Pretty much yes
MᏫᎻᎯᎷᎷᎬᎠ
Well
It's packed with size() member so you can pass it as a function argument without worrying too much for that
BinaryByter
yes, there's that
MᏫᎻᎯᎷᎷᎬᎠ
Second, it's handled if you get out of its bound
BinaryByter
Why is that better than a sigsev?

Exception
BinaryByter
segfault
BinaryByter
why is an exception better than a segfault?

Exception are occured before the segfault happens
BinaryByter
what does that mean?

btw ^^

Exception doesn't allow the error to happen
BinaryByter
well in both cases the error doesnt happen
