It all can get stupidly complicated as we've seen, but the syntax follows simple rules: 1. start reading from the identifier out 2. favor [ ] and ( ) over * int (*(*x)[ ]) ( ): - Following rule #1, we start at x x - The identifier x is alone in parentheses with an asterisk, so it is [§1] a pointer *x - Outside of the parentheses, we follow rule #2, so it is [§2] an array (*x)[ ] - We're left with an asterisk inside the parentheses, so [§3] pointers *(*x)[ ] - Outside of the parentheses, rule #2, [§4] functions (*(*x)[ ])( ) - The functions return [§5] int putting §1, §2, §3, §4 and §5 together: x is (§1) a pointer to (§2) an array of (§3) pointers to (§4) functions that return (§5) an integer Once you got the hang of it, you can rewrite the example like: * [ ] * ( ) -> int And stitch things together in a way that makes sense. "->" means "returns" and it's optional/redundant (anything immediately after parentheses in this notation is a return anyway) Take the example of 5:34: [ ] * * (* char, * (* char) -> * int) -> [ ] * (* * char, * ( ) -> * char) -> * int Array of pointers to a pointer to a function that takes (a pointer to a character and a pointer to a function that takes (a pointer to a character) and returns a pointer to an integer) and returns an array of pointers to a function that takes (a pointer to a pointer to a character and a pointer to a function that returns a pointer to a character) and returns a pointer to an integer It looks insane, but it's not that difficult to wrap your head around if you're writing it following those two simple rules

C believes that smart users know that the void* returned by the function is a specific type among the 100+ custom types, it will be a linklist + table with a specific internal mix of pointers to stack and pointers to allocated heap, and then you have to be careful about pointer casts, linklist iteration, use void* to calculate offsets, of course you will remember which one is CHAR8* string and which is CHAR16* string, finally free the heap allocation and perfectly avoid the pointer to the stack. The biggest advantage of C is that it is suitable for keeping your job.

In older computers, especially Lisp machines, pointers always came with a size. A pointer was a 2-D object to the hardware. It had a location, and a size. The weirdness of C/C++ pointer types is an attempt to recapture some of the elegance of earlier hardware in a later era where the hardware forgot about data safety.
@mage36905 ай бұрын
Location + size pointers are referred to as "wide pointers" in modern C++, AFAIK. You're right though -- C's syntax is a desperate attempt to make the size portion of a wide pointer into a compile-time issue rather than a run-time issue, mostly for performance reasons.

I finally understood. The type signatures are provided not the obvious way around, but outside in. For example: int x() is a function named "x", returning an integer. But instead of "x", I can put something different and it will mean, put the whole function inside whatever is in that position. For example "int (*x)()" means to put the function inside the *x. So It's a pointer to a function. But it's not just functions, it's **everything** if we analyze the "int (*x)()" again we get: int , which means to put the integer inside something that something: () It's a function! which means, that we put our int iside the return paramater of that function what's something: * it's a pointer! which means, we put our whole function with integer return type into a pointer. that something: x It's a name "x" which means, we put our whole pointer to a function with a return type of integer into the name "x" Let's do another example: char *(*(*(**x[])())[])(); it's a char, which is in a pointer, which is in the return type of a function, which is in a pointer which is in an array which is in a pointer, which is in the return type of a function, which is in a pointer, which is in a pointer, which is in an array, which is in "x"

Its doesnt matter here, yes, but this also reminds you how other operators work like array access and dereference operators. *x[8] means "take the 8th member of x and dereference", where as (*x)[8] means "dereference x and take the 8th member of that"

The way i look at it is, the way you declare a pointer, is the way you access it. So if you got int *(*p[]), you'd access the innermost value (being the int) in the same way: *(*p[i]). And then you work your way backwards To make the point(er) clearer ill go through this. So you access the int by doing *(*p[]), so *p[] is an array of pointers to int, and *p points to an array of pointers to int, and p is a pointer to an array of pointers to int

A pointer consists of: 7, 9, 9, 9, 9, 9, 12. I.e. 7 bits unused, 12 bits for the physical offset in memory and the 9's are offsets into a page "tree" if you will . Most CPU's today only use four-level pages, so the top 16 bits (instead of 7) are unused - but Intel is starting to use five-level pages too. It's also why pages are 2^12 (4096) in size, and why large pages can be 2MB (2^(12+9)) and 1GB (2^(12+9+9)) respectively. You can cast a pointer to a number, and shift the bits into different values to clearly see how there's a clear pattern when you allocate memory etc.

Pointers are like your fingers, fingers that are pointing at something (aliased "x"), that object "x" is stored in an area known as the memory address A pointer holds the memory address containing variable "x" To obtain the value located in the memory address of variable x pointed by the pointer, use `&ptr` Now, a pointer to a pointer holds the memory address containing the original pointer object pointing to variable "x" above Repeat to keep getting the memory address of everything the previous level is pointing

Pro tip: if you have to use raw function pointers in C++, use the new style of typedefs: using Func = void(int, int); Func* x; - much more readable IMO. In general, avoid declarations that sandwich the identifier in the middle like the plague.

The biggest problem with pointers is batshit insane C syntax.

3:29 --> See line 15 (3:21) for further clarification. In short, line 25 is saying that you want to first dereference the pointer, followed by selecting the function at index 0 for that pointer; then you have to de-reference that index (the array itself decays to a pointer containing the addresses of each function) in order to call the function you want from that double pointer. i.e., createFunctionPointerArray() returns "& -> {&add, &subtract}". You're making an embedded function library, I guess you could say, that the variable references, and you have to dereference all those pointers to access the function you want. Easy to understand?

I'm assuming the brackets that aren't used or don't have anything in them are just placeholders for new nested variables and code to be added in the future?... Either that or code that already exists with those brackets in mind and are connected to similar code.

im new to the concept of pointers and memory allocation, since i just started learning c++ a few days ago. decided to spend an hour or so looking at this after learning the basics of pointers until i feel like i understood enough about how it all ties together, i guess i learned more about it but now i have a painful headache...
