Depends on the implementation of message queue

Can you give me more details?

If the message queue implementation supports different types of messages, then it's possible. You need to refer to the documentation of the one that you use. If you implement it yourself, you can do that either by having virtual base class or using std::variant or std::any

I'm programming in C not in C++ and I need message queue as IPC I'm not implementing anything

Ah, OK, you should have mentioned it :) then I have no idea

This is a university project that I want to solve. Can I send a picture of the project or not according to the laws???

Do laws forbid that?

Of course NO

Of course NO

Yes it's really rude way to say it

He could have told it kindly

Yeah

Perhaps. But like isn't this group ment to help someone?

At least you should have asked what he wanted?

What programming language(s) are you familiar with?

Oh okay. Python really isnt my strong suit ^^. Either way, pointers can be very useful for a lot of reasons but one example would be to pass something big by "reference". Like if you have an instance of a big struct you can pass a pointer to that instance in order to access its members without needing to copy the whole thing. Another thing is also the same situation and you want to modify the struct directly and not modify a copy of the struct.

Its also mich faster in execution time to only move a 4byte pointer instead of the whole struct :)

Is there any alternative for <ncurses.h> in C++? I need to use getch() but this header throws an error /usr/include/curses.h: In function ‘int main()’: /usr/include/curses.h:254:8: error: expected unqualified-id before string constant 254 | extern "C" { | ^~~

It looks like it's a C++ header being compiled as C?

I was using g++ whole time

#ifdef _WIN32 const char CLEAR[3] = {'c', 'l', 's'}; #include<conio.h> #else const char CLEAR[5] = {'c', 'l', 'e', 'a', 'r'}; #include<ncurses.h> #endif

so these are the first lines of code?

nah, i have a game class before that

#ifdef _WIN32 const char CLEAR[3] = {'c', 'l', 's'}; #include<conio.h> #else const char CLEAR[5] = {'c', 'l', 'e', 'a', 'r'}; #include<ncurses.h> #endif

i had a semicolon before pasting it, i put this code before main(), class and the other functions and it works somehow nevertheless, i'm very grateful for your support :)

Do anyone know about prime sieve array? I was watching a tutorial and in it the tutor was saying that the sieve array can be at max of size 10^8. Can anyone tell me why

class Singleton { private: static Singleton *m_singleton; public: static Singleton &Get() { return *m_singleton; } void Print() { cout << "we are inside singleclass " << endl; } }; Singleton* Singleton::m_singleton=nullptr; int main() { Singleton::Get().Print(); Singleton::Get().Print(); Singleton::Get().Print(); Singleton::Get().Print(); }

But my doubt is here "m_singleton" is intialised with nullptr right....and we haven't assigned that ptr to anything

So in the end.....Get() func should return a Null obj reference isn't???

This is the doubt

c and python i am currently learning now and moreover i know how to use them i want to know its usage in real life programs

1.Actually it is very helpful and mostly used in case when you create dynamic object at run time by malloc,realloc...etc 2. In manipulation of string.

What is the meaning of manipulation of string
