Answer 1

0x0 can be hold by long l not by char
and in union u dont access members

Answer 2

I believe what you are looking at is a struct. If you are more familiar with object oriented programming, think of it like a class. You could declare something as being of type 'union' and assign things to its member variables, the char array and the long. Unfortunately, having not used these much myself, I am not familiar with what u={0x0] is doing.

Answer 3

unsigned char c[4]; is an array... you can see it like that.
c [0, 1, 2, 3 ]
and u.c [0]
is associate Array u.c [0] it means it hold 0 value

Answer 4

i have no clue!!
