Thank you.

Answer 1

why am I incorrectly referencing a pointer in a struct?

zmienna_strukt.a=NULL;
...
scanf("%s", wsk->a);

You refer correctly, but the pointer points to NULL. It is impossible to read there scanf'om. In order to be able to read, it is necessary that the pointer points to the allocated memory of sufficient size. For example like this:

struct morgan zmienna_strukt;
    struct morgan *wsk;
    unsigned char buf[100];

    wsk=&zmienna_strukt;

    printf("Впиши значение: ");
    fflush(stdout);
    scanf("%d", &zmienna_strukt.b);
    printf("%d \n\n", zmienna_strukt.b);

    zmienna_strukt.a=buf;
    buf[0] = 0;
    printf("%s \n\n", zmienna_strukt.a);

    printf("Впиши значение: ");
    fflush(stdout);
    scanf("%s", wsk->a);
    printf("%s \n\n", wsk->a);
