It would be very nice, if you make a video or a series of videos explaining everything about git, and github and so on, please

hello sir , could you make a video about the Dining Philosophers problem using mutexes in c. (threads)

hello can you explain / implement the heap in c? I found your stack video very helpful in understanding the concept and would like to view the heap in depth as well

I will look into it

Hello Sir You are very helpful To me may i know sir where are you now ? Please Start regular lecture I love and Studied from your video hope we can see you again And All the best to you whatever you doing you will got sucess God Bless!!

[@CodeVault]

Will do. Thanks for the support

[@QanarIsDelirious]

this helped me alot fix some logics behind recursive exam quests :D in all but one of them the print of the recursive function did just "print" the finished value that was called in printf %d , function ... but this one bugger returned a number-- and i didnt get it that the system returns 2 values the untouched value and the decremented one.. and it shows the untouched one return to the print .. waited for the "for" loop to end and then before it opened the next recursion it then accepted its decremented faith xD .... the hardest part to C is just that these small littl logics that our professor understands at 3am drunk.... isnt integrated in all fine details in us when he explains the core function of the project he uses :D

[@riccardosebastiani4571]

Good morning Sir, could you do a video about pointers of array of struct? Like this: Struct struct_1 *p[ ] ; I mean, how can I use them in other functions (Not in Main)?

[@riccardosebastiani4571]

My program is working now! If you guy need help, use malloc for each index of the array and use *p[ ] in the prototype. Use the arrow operator ( p[i]->something ) REMEMBER to free each index

[@riccardosebastiani4571]

Anyway, I think is good idea doing a video about array of pointers. This can help everyone

[@CodeVault]

There is this video: code-vault.net/course/ar67avx6hk:1610029043923/lesson/he9jn5x8b1:1603733522083 But I will also keep in mind and make a video specific to your problem

[@bartlomiejodachowski]

Hi, is there video of yours where you mention about arrays size of 0 ???

[@CodeVault]

Arrays that have size = 0 you mean?

[@bartlomiejodachowski]

@@CodeVault yes. for example thre is a trick like this: typedef struct Message { unsigned id; char text[0]; }M; M* m1 = malloc *(sizeof(M) + sizeof(char)*n)* ; _//now m1->text has size n instead of 0_ works only when empty array is last member of a struct, but what is this empty array?

[@CodeVault]

Apparently it's called "flexible array member". Here's more details: stackoverflow.com/questions/36577094/array-of-size-0-at-the-end-of-struct I might make a video on this as I never used such a feature

[@bartlomiejodachowski]

@@CodeVault thanks :D I'm looking forward it

[@ForeverNils]

Can you please explain why do you use GCC why not CLANG?

[@CodeVault]

You can use whichever compiler you want. The only reason I use GCC is because I was familiar with it on Linux, that's about it

[@donttrackme8590]

What happen when we compare two variable from different types in C (in x86 arch) ?

[@CodeVault]

You usually just get a compilation error

[@tigranav.3960]

is ++a actually faster than a++ for base types (not for iterators)?

[@kingneo4913]

Yes! Not much, but yes

[@CodeVault]

That's an interesting question. From what I read ++a and a++ in C, for integers, without using their values are exactly the same (the compiler does some optimizations). If using the value, you should expect that ++a is better since a++ has to store a temporary value and then increment a. Here are some links: stackoverflow.com/questions/24901/is-there-a-performance-difference-between-i-and-i-in-c stackoverflow.com/questions/24886/is-there-a-performance-difference-between-i-and-i-in-c/24887#24887 Now, I haven't fully researched this and certainly not on multiple architecture and compilers. If anyone else knows a better answer please feel free to post it here and I'll pin it!
