C question about sizeof()

    char x, s[5], *p = NULL;
    int y, a[10], *q = NULL;p = &x;
    q = a;
    printf("char: %ld, int: %ld\n",  sizeof(char), sizeof(int));
    printf("x: %ld, y: %ld\n",  sizeof(x), sizeof(y));
    printf("s: %ld, a: %ld\n",  sizeof(s), sizeof(a));
    printf("p: %ld, q: %ld\n",  sizeof(p), sizeof(q));
    printf("*p: %ld, *q: %ld\n",  sizeof(*p), sizeof(*q));
}

char: 1, int: 4
x: 1, y: 4
s: 5, a: 40
p: 8, q: 8
*p: 1, *q: 4
