Hello and good morning. I need your help. Can someone explain this coding?🥺
...
...
Sorry for my bad english. 😅
...
I mean .. how does pointer and array work ? 🤔
Artöm
Who knows...
...
The pointer chapter .. for me, it's kinda hard understand😭.. just like, it can be swap wih the variable.. and .. I don't undersatnd🙂
...
And now .. it make me more not understanding .. ughhhhh
Mar!o
in the last line they iterate over array
Mar!o
a+n is the array end address
Mar!o
you can do pointer arithmetic like with an int

int 2 byte , char 1byte
...
Owhhh .. I see.
...
int 2 byte , char 1byte
I'm sorry. Can you explain, why char 1 byte 🤔 ... the coding show integer, right?😅

Google for search is better

Allright, thanks for help❤️😊

For Linux
Use GCC compiler
>GCC filename.c
>./a.out
For window
Install turbo c++, code block, dev c

Thank you very much for welcoming me

Why virtual functions can't be a templates?
MᏫᎻᎯᎷᎷᎬᎠ
Well template functions instantiations are known at compile time🤷🏻♂
MᏫᎻᎯᎷᎷᎬᎠ
The overload resolution is known at link time
MᏫᎻᎯᎷᎷᎬᎠ
That's why
MᏫᎻᎯᎷᎷᎬᎠ
Yeah
MᏫᎻᎯᎷᎷᎬᎠ
Thanks Madhu

How will be names lookup in C++20 modules?!
I mean
You define a module A in file b.cpp
And then you import A; in file main.cpp
How does the compiler know the module location, unless you supply that information as an arguments with g++, but it's a little bit painful if you have tens of files
In the include system you specify only the path, so it's known to the pre-processors
MᏫᎻᎯᎷᎷᎬᎠ
Or someone has to use Cmake Everytime huh!!
MᏫᎻᎯᎷᎷᎬᎠ
Okay
Thanks again :)

Hello guys, I came across an Object-Oriented programming based question. I have been trying to figure out which one to make the base and derived classes and I really got confused. Please give me a head up on how I can tackle the question.I don't need the code, just the frame
Here is the question
A car bazaar deals in various types of vehicles including cars, vans, buses, minibuses, trucks, pickups among others. A bazaar management program is required to keep track of these vehicles and the activities that happen to them. The bazaar also assigns employees to be responsible for the marketing, sales and maintenance as well as security services for these vehicles. Assume the bazaar operates within Nairobi and has at least three branches.
Required:
A design of the said program clearly outlining classes (base and derived) and their corresponding data members as well as any relationship between the classes.
A program to:
Keep track of which vehicle is in which branch at any particular time.
Keep track of which employee is in which branch
Which employee has worked on (marketed, sold or repaired) which vehicle.
Using C++ and employing OOP concepts, implement the required program, clearly outlining how you have used the concepts of: Classes, Objects, Encapsulation, and Inheritance.

I am getting error like below
error: no matching conversion for functional-style cast from 'std::unique_ptr<MockHealthCheckEventLogger>' to 'Envoy::Upstream::HealthCheckEventLoggerPtr' (aka 'unique_ptr<Envoy::Upstream::HealthCheckEventLogger>')
where MockHealthCheckEventLogger is inherited from HealthCheckEventLogger.
In my code event_logger_ is initialized as below
std::unique_ptr<MockHealthCheckEventLogger> event_logger_{ std::make_unique<NiceMock<MockHealthCheckEventLogger>>()};
problem solved if I am using a raw pointer
like MockHealthCheckEventLogger * event_logger_{ new MockHealthCheckEventLogger()};
I have to use a smart pointer here. Does anyone suggest how to implement that?
Hermann
a trivial question ... if I declare an array is large enough instead of accurately calculating its size do I have performance problems or something?
Manish
Mα∂ɦµ MockHealthCheckEventLogger is derived from HealthCheckEventLogger. and if I am using raw pointer there is no problem. Issues occur when using unique_ptr
Manish
Mα∂ɦµ void allocHealthChecker(const std::string& yaml) {
health_checker_ = std::make_shared<TestHttpHealthCheckerImpl>(
*cluster_, parseHealthCheckFromV2Yaml(yaml), dispatcher_, runtime_, random_,
HealthCheckEventLoggerPtr(event_logger_));
}
Error is at HealthCheckEventLoggerPtr(event_logger_));

Hi

Thanks

Hey guys, is there anybody out there willing to help me out with my AfterEffects project. If so, please DM me.
Hermann
is it better to use a malloc or a fixed size with the problem of wasting memory?
Asdew
That depends.

if you would remove/restrict idiots from this groups, it will be a pleasure
J.
The thing is anybody can ask stupid questions but it is seriously annoying to read warnings and bans the rules everytime. Admins please take care of it it is ugly.
J.
It's a great platform I just told my opinion sorry I have no time for this because working on a lot of projects right now. Whatever.
