I personally think that it is a way to practice arrays and pointers that way

otherwise you sometimes don't even need to create an array sometimes in certain problems

can i make facebook clone with c++?

No

Facebook is mainly a webapplication, try html, css, js, php and sql

can i make facebook clone with c++?

of course, you can do everything with any Turing completeness language

actually Facebook uses c++

Really?

How do I use an extern class?

Yeah, for backend. I was talking about front end. Probably every big company uses C or C++ one way or the other. It is a must. Thanks for sharing though, I didn't know that

How do I use an extern class?

extern std::vector<commsyPost> libCommsy::posts; static data member definition cannot specify a storage class

Yeah, for backend. I was talking about front end. Probably every big company uses C or C++ one way or the other. It is a must. Thanks for sharing though, I didn't know that

I don`t think so if you mean uses = coding. there is monopoly for web frontend

probably you can use c++ webassembly, or don`t use Javascript at all. anyway is possible

Again: none for you

If you ask questions like this, you won't get a job interview right now

Why?

Why?

Because you do not understand how developers work and what developer you want to be

Don't judge a person

Lol

Don't judge a person

I'm not judging you I'm just stating a fact

Minimum how much languages we want to learn while going for job interview?

You're not proficient in a single language, you should be proficient in the concepts that apply between them, Working with a developer to teach them a new language is half a year if not less, but having someone learn the logic behind it that is a much less forgiving task.

If you dont know the theories, concepts and co behind the language(s) and your computer however there's always wordpress template designer positions open.

But I know C, C++, java, Csharp, python

Y u say so?

I know it

How do I define exceptions in another object file?

Like i have libcommsy.o and main.o And libcommsy.o has specialised exceptions

How do I define exceptions in another object file?

what do you mean "define exceptions"?

add class as usual

what do you mean "define exceptions"?

like extern <exception> Which does not work

add class as usual

Undefine reference

#include <exception>

#include <exception>

I did that

I know it

If you are able to solve problems from hackerrank using C++, it doesn't mean you know it

#include <exception>

My class in the header file: class libCommsy { public: ... // Exceptions class invalidSIDError; class invalidRoomError; class invalidPostError; class descDownloadError; }; libcommsy.cpp: // Exceptions class libCommsy::invalidSIDError {}; class libCommsy::invalidRoomError {}; class libCommsy::invalidPostError {}; class libCommsy::connectionFailError {};

If you are able to solve problems from hackerrank using C++, it doesn't mean you know it

How can u say I solved C++ problem in hackerrank

How can u say I solved C++ problem in hackerrank

Because I don't think you have written anything besides hackerrank-like problems

You just need to learn to be realistic

Thank u 4 ur advice

So you do not know C++?

Great

So you do not know C++?

I know it

Then answer the questions https://t.me/programminginc/320558

If you know C++

If you do not answer, you do not have a clue about C++

If you do not answer, you do not have a clue about C++

I know the code

ANSWER THE QUESTIONS

I don't want to show u

I know it

Ok so you're officially admitted that you do not know C++

Good luck with finding a job

Lol

It's a type trait to determine if one class is base of another struct Base {}; struct Derived : Base {}; struct NotDerived {}; is_base_of<Base, Derived>::value // == true is_base_of<Base, NotDerived>::value // == false

Type traits is not a basic topic of C++

You don't have to know what they are unless you claim that you KNOW c++ or have a specific job with templates in C++

I think the person even do not know what undefined behavior is and never saw a C++ standard document

#include<stdio.h> struct array { int A[10]; int length; int size; }; int reverse (struct array *p) { int i,o ; for(i=p->length;i<=0;i--) { o= p->A[i]; return o; } return 0; } int main() { int q; struct array s={{3,4,5,6,7,5},5,10}; q=reverse(&s); printf("%d",q); }

would this print array in reverse order?

i am getting error like the loop will run atmost 1 time

I think the person even do not know what undefined behavior is and never saw a C++ standard document

U r right I know only to solve C++ fundamental codes

#include<stdio.h> struct array { int A[10]; int length; int size; }; int reverse (struct array *p) { int i,o ; for(i=p->length;i<=0;i--) { o= p->A[i]; return o; } return 0; } int main() { int q; struct array s={{3,4,5,6,7,5},5,10}; q=reverse(&s); printf("%d",q); }

for (int i = p->length - 1; i >= 0; --i)

U r right I know only to solve C++ fundamental codes

Yes I did a mistake there but i corrected it later and again the compiler responded that increment never executed

If you do not what undefined behavior is you're a noob in C++

Can you tell how grow in coding

Read books and code projects, not only hackerrank projects

Can you provide a path on your experience
