Hey, so I've been searching the web for a while for some popular applications that use C. All that I can find so far is, Git, Vim, Linux, and Unix. I also know the Windows kernel uses it a little bit, but that's it. Does anyone know some popular apps that use C? Doesn't have to be programming related, just an actual app that's written in C? Sorry if this question sounds redundant or anything.

Hey guys, I made pong clone in Golang with Raylib. Was wondering what you all thought about it.

I'm trying to create a dynamic array which can be modified using the functions Array_Push(array, val) & Array_Del(array, index). Now the current way I have this I need a variable to keep track of the size of it. My implementation of this concept is to store the data/size in a struct like so:
 struct Array {
  void **data;
  int size;
 }
However in order to read the actual array you have to type array.data[i] which I think is a little bit redundant. My solution to this was attempting to store the size of the array in a different index. I didn't want to store it inside [0] as that would create a lot of confusion, so I wanted to try storing it inside of [-1]. An obvious problem with this is that [-1] is outside the array. What I did instead was create an array via void **array = malloc(sizeof(void*) * 2) (the * 2 is so when you push with realloc() it doesn't free empty memory,) then setting the size via array[0] = (void *)0. After that I increment the pointer to it via array += 1. However when I try to free it free(array - 1), I end up freeing non malloc()ed. I think this is just an issue with my understanding of pointers, so I wanted to ask where my logic is going wrong, along with if anybody actually knows how to do what I'm trying to do (in the title).

Ok, so I've been thinking for a bit, and I know there's a ton of alternative "libre" frontends for websites like YouTube and Reddit. However, I was thinking: what If I just wanted to make my own frontend? Not specifically for the intentions of "libre", but I wanted to change the controls and appearence of the website. I'm honestly unsure of how to approach this. Any thoughts?
