Compile time error

its not

It is not = delete d

if my template class has pointer members of the template datatype and i delete them in the destructor. everyrhings ok?

Why do you allocate manually in the first place?
Vlad
Especially if your class is clearly a data owner
Vlad
Use unique_ptr's instead

ok going to read docs. thankyou

VB SUCKS... Even though back in 1996, I started Windows programming using VB... but trust me it SUCKS.
I know a guy who wrote 2d game engine in VB back in the day :P. He works at Sega now

Good for him but I'm sure in Sega he doesn't work on VB anymore.

one more thing visual studio gave an error invalid address specified to RtlValidateHeap(...)
upon deletion of a pointer.
what could be the reason?

Vlad
Looks like you should cover the basics first, bruh.
Z0OM
yes it was

is someone free? i really need help. i have spent 1 and a half days to figure out just whats wrong with code. tried debugging logging output. but i am unable to figure out whats wrong. if someone can buy the time to look in my code I would be very thankful. but code is very big. multiple classes. ~Thankyou
Vlad
>multiple classes
>big
That's how many? 5 or smth? :P
Z0OM
i guess the mistake is somewhere in one of the 3 classes.

What external libraries do you use? And, is your code runnable on Qt+mingw on windows?

yes linking is fine. there are no errors. but code is not doing what i want it to. the problem is in basic c++.

I'm going crazy by libuv, shit-like handle off. uv_timer_t this immediate end is going to have to wait to close.

Dev C++ is outdated af.
Never use it, if you encounter errors no one will help
What about codeblocks?
Vlad
last update was on Thursday, 19 March 2020
As far as I know it supports only MinGW and vs2010 compilers
Vlad
And mingw still hasn't got c++17 implemented
Vlad
And also a pain in the ass to develop for
Merazi
And mingw still hasn't got c++17 implemented
but it supports GNU GCC, that even supports the new c++20
Vlad
And it drags. And always did.
Merazi
Then codeblocks would be good only if you're running linux(?
Vlad
The only reason in the universe to use it. That if you port posix heavy program on windows
Vlad

It's fine for linux. But editor is still dated and lacks some functionality.
Andrew

no, there better code editors on linux for C

Hi do you guys answer c programming questions?

Depends... if it's not based on question paper.
Don Peter Joseph
i have a doubt
Don Peter Joseph
p1=(struct poly*)malloc(n1*sizeof(struct poly));
Don Peter Joseph
can i write like this where p1 is not a pointer
Don Peter Joseph
c
Don Peter Joseph
p1 is a structure variable
Don Peter Joseph
i dont know
olli

Are you sure about that? My MinGW GCC supports coroutines and quite some C++ 20 features. A lot of MinGW patches are accepted upstream by GCC, just count how often "mingw" is mentioned in their codebase
I don't see where all the "hate" for mingw comes from, it's easy to setup, easy to use and at least my version is pretty much up to date with upstream.
olli

If your compiler implements uintptr_t you can do this
uintptr_t p1 = (uintptr_t)malloc(n1* sizeof(struct poly));
I don't know whether this would make sense in your case tho, why not just use a pointer?

/report ethical homework go brrrrr

i want to make a question, do you guys prefer
if(statement)
{
expression
} or
if(stamement){
expression
}

I prefer the first one as it is more readable for me

We prefer a pasting service

What about codeblocks?
codeblocks might lack some functionalities as other said.
But, considering the smaller size of installer, I guess that codeblocks is more appropriate for not powerful computers.
It also has wxsmith (a visual editor for wxwidgets) which makes it one of few options for this

Ok. I almost uninstalled it remain only with visual studios
