Hi guys, I have a question; it is well known that for polymorphism, we use virtual destructor to avoid memory leak. Typical example without the virtual keyword for destructor shows that if a member of parent class is a pointer, then the memory on heap cannot be freed. However, how about a typical int member of the parent class. Without calling the parent destructor (consequence of not having virutal destructor for polymorphism), will a typical stack variable be freed?

stack variables are freed automatically, you don`t need destructors for them

it is true that no code need to take care of the stack memory management, but the thing is, the end of a class is typically marked as the call of destructor, but without even calling it as a bug under polymorphism, does it really end?

the end of a class instance

i mean, will it happen to be only destructing the child part instead of parent part, if the destructor is not virtual

Well you should not call delete by a base pointer

If you don't have virtual destructor

i mean, will it happen to be only destructing the child part instead of parent part, if the destructor is not virtual

that is undefined behaviour.

Is using the result of an assignment expression allowed?

Hi! Are there any possible chances to make circle diagram on pure c++, that’s what my teacher in university told me to do

https://github.com/ssloy/tinyrenderer/wiki This is as pure as it gets without any external graphics api's

Yes, you could manipulate images such as the example above shows

Go ahead and ask your query but be sure to read rules if you havent already

Klimi just told you to read the rules

fread(this_kb->event_buf, sizeof(*this_kb->event_buf), 1, this_kb->kbdev); Any idea why this causes a segfault from time to time?

It could be anything

It may not be not even this line :P

It could be anything

solved by recompiling

Just had to hit the compile button again :P

solved by recompiling

By recompiling whole project?

make clean make -j

Is this computer knowledge related group.

UB??🧐

ohh!!

Like what cases exactly, other than the memory is full?

I've read that the OS do some virtualization processes in case if the memory is full like using the HDD for swapping the unused partitions of your program for later use, which frees some space in the RAM

I think that is how every 30+gb games or heavy softwares are handled

Yes it's outside of the scope, but has an affects for C++ runtime whether to throw std::bad_alloc or not

Patterns like what?

Okay Thanks

hello, someone can explain how to "compare" function is called without brackets and args? #include <stdlib.h> #include <string.h> #include <stdio.h> int compare( const void *arg1, const void *arg2 ); int main( int argc, char argv ) { int i; argv++; argc--; qsort((void *)argv, (size_t)argc, sizeof(char *), compare); for( i = 0; i < argc; ++i ) printf( " %s", argv[i] ); printf( "\n" ); } int compare( const void *arg1, const void *arg2 ) { return strcmp( * ( char ) arg1, * ( char** ) arg2 ); }

I know is a pointer to a routine in function qsort, but how function qsort can call compare function?

I mean the code in qsort to call compare function, thanks

void func(void (*func_ptr)(int)) { func_ptr(5); //this is your call }

void func(void (*func_ptr)(int)) { func_ptr(5); //this is your call }

tnk bro

hello, I'm doing a program. In this program, c# applications are called.

https://www.codeproject.com/Articles/1236146/Protecting-NET-plus-Application-By-Cplusplus-Unman

I'm editing this. The program is correct yet I need to detect and prevent memory leaks.

I don't want the C# application to be accessed via memory. Can you help me?

What will be the logic for digit to word conversion in C++ ?

What will be the logic for digit to word conversion in C++ ?

Ex:- 1047 -> One Thousand Fourty Seven

Perhaps you can load and read a json file. Like maybe you have one json from 0 -> 10, and another from 10 -> 100, then 100 -> 1000, etc.

Ex:- 1047 -> One Thousand Fourty Seven

Then just use some conditional statements to figure out which json file should be read

Or you take a look at nlp, I think that could help. Idk though

because that's not a VLA, nor is the warning related.

He's using non const int, it's indeed VLA

Btw flag for it is -Wvla

Then just use some conditional statements to figure out which json file should be read

I've got one logic but it's taking so much codes again and again. I'm doing this by changing some range of numbers by copy paste.

He's using non const int, it's indeed VLA

not in his variant, as he'll never re-enter main, thus, the array will only be initialized once. in the case of any other function - yes, you could have a VLA on the stack.

either way - that wasn't even the error he faced. it was not using the array anywhere

okay, and when's the variability in that arrays length gonna come in?

variable in all caps :P

lol

and where does 'a' get its value from?

do you even understand what a VLA is?

It's probably a GCC extension
