    There's nothing to master in pointers, pointers are literally addresses of memory, idk what you see is complicated in that, whenever you need the value/content in that memory address you de-reference it using the asterisk *, that's all there is
    Additionally, double pointers are pointers that point a place in memory where a pointer is stored and it's the same for triple pointers ....

        the use of the asterisk in C is completely moronic, since the asterisk can mean either DEREFERENCE operator, or pointer (aka REFERENCE) type, depending on where it is.

    you just dereference an address in memory and what is used in the operation si what is stored at the line of addresses the size of the type of the pointer starting from the address in the pointer and going up.
    >multi-dereferences
    they dont even exist machine code but its just
    >look to address, read 8 bytes of values, look at the address they point to
    etctec

      No because it's a pointer to a pointer, so it's an integer that contains the address value of another integer value that points to an integer.

    Pointers are just indexes
    Thing of the memory of your program as just being a giant array of bytes
    And pointers are just indexes into that array that refer to different width chunks depending on the pointer type
    So an int* refers to the starting index of series of bytes in the array big enough to store an int

    They're just numbers representing addresses.
    What confused me for an embarrassingly long time was the arithmetic, then I realized that the `+ 1` for a pointer wasn't the same as the normal `+1`.

        The address is a number.
        A variable, say an int, is a number stored at an address.
        The pointer is a variable, say a size_t, that stores the number of the address of the other variable.

    I feel like it's the C syntax that trips people up, not actually the pointers. At least that was the case for me a long time ago when I first learned about pointers.

    Imagine you have an array
    A pointer is an item in the array that holds the index to another item in the array
    A double pointer is an item in the array that holds the index to the other pointer.

    The array is your memory.

    why would you use pointer? do they use less resources when you invoke them instead of using the variable directly?

      You could avoid pointers by passing back and forth the entire state of the program as an argument like those functional frickwits
      I'm sure copying gigabyte of memory on each function call is an acceptable sacrifice in exchange for never having to learn how to manipulate memory correctly
