I think it is because bit1 is only 1 bit fwide and whn u initialize it to
1,since MSB is 1 it treats it as a negative integer...Plz correct me if i am
wrong...

Int bit3:4 will be read as lower order 4 bits of bit3 and this will be
treated as int (signed). Thus lower order bit of bit3 which is 2, are
0010 which is 2
try with
1) int bit3:2, output will be -2
2) unsigned int bit3:2, output will be 2.

I hope it is cleared now

Re: [algogeeks] output help

On a little-endian machine, bit structure will be represented as:

 0x00 00 00 45

which is bit.bit4 = 0010 (2 in decimal) bit.bit3 = 0010 (2 in decimal)
bit.bit1 = 1 (1 in decimal)

since bit.bit1 exists at the rightmost position, while displaying data as
integer, compiler just repeats the same bit to all the remaining positions
making it 0x (-1). You can confirm it while setting bit.bit1 to 0

using typedef u define the static keyword as int
and the statement static int j thus becomes
int int j

hence the compiler gives the error multiple storage class in declaration
specifiers

typedef doesn't declare an instance of a variable, it declares a type (type
alias actually),

static is a qualifier you apply to an instance, not a type, so you can use
static when you use the type, but not when you define the type.
