I think the error in your code should be in how you are calculating the average of letters and sentences per word: float averageWords = sentences / words * 100 and float averageLetters = numberOfCharacters / words * 100;. You should actually multiply letters and sentences by 100 in each formula and then divide by words.

I found this example, really cool.
The function has been converted to a pointer.
int * onefunction()
{
static int returnA[2];
returnA[0] = 1;
returnA[1] = 2;
return returnA;
}
void main()
{
int *callfunc;
int a, b;
callfunc = onefunction();
a = callfunc[0];
b = ...

You can't return an array in C. You end up returning the address of the local array, which then gets assigned to your myReturn variable.

This (JpegBlocks[0] = 255) uses the set operator, not the comparison operator.
This allocation char StrFileHolder[7]; won't accomodate the null terminator when sprintf creates the string.

int sepiaRed = round((0.393 * image[h][w].rgbtRed) + (0.769 * image[h][w].rgbtGreen) + (0.189 * image[h][w].rgbtBlue));
int sepiaGreen = round((0.349 * image[h][w].rgbtRed) + (0.686 * image[h][w].rgbtGreen) + (0.168 * image[h][w].rgbtBlue));
int sepiaBlue = round((0.272 * image[h][w].rgbtRed) + (0.534 * image[h][w].rgbtGreen) + (0.131 * image[h][w].rgbtBlue))...

You seem to be confused about malloc(). malloc allocates memory from heap. You can store anything inside this allotted memory location.
Specifically it expects the following input: number of bytes of memory you want to be allocated.
int *ptr;
ptr = malloc(sizeof(int));
*ptr = 300;
printf("Address of ptr: %p\n", ptr);
printf("Value inside ptr: %...

char *flname = "0.jpg";
The string here is immutable. Writing to it again is undefined behavior. You need to stack allocate space for a file name. 000.jpg is 7 characters and you need one extra byte to store the null terminator so 8 characters will do it. char flname[8]; You almost had it.
In essence, I'm not sure what I could use to close the ...

My understanding is that list is a pointer variable initialised
without a value
No. It's initialized to NULL. That's what the = NULL part does. A variable can't be initialized without a value. Initializing means assigning a value. Uninitialized meaning memory is allocated, but you didn't write anything to it. Maybe this is what you meant, a pointer being ...
