how is data stored at bit level according to "Endianness" ?
- by bakra
I read about Endianness and understood squat...
so I wrote this
main()
{
int k = 0xA5B9BF9F;
BYTE *b = (BYTE*)&k; //value at *b is 9f
b++; //value at *b is BF
b++; //value at *b is B9
b++; //value at *b is A5
}
k was equal to "A5 B9 BF 9F"
and (byte)pointer "walk" o/p was "9F BF b9 A5"
so I get it bytes are stored backwards...ok.

so now I thought how is it stored at BIT level...
I means is "9f"(1001 1111) stored as "f9"(1111 1001)?
so I wrote this
int _tmain(int argc, _TCHAR* argv[])
{
int k = 0xA5B9BF9F;
void *ptr = &k;
bool temp= TRUE;
cout<<"ready or not here I come \n"<
for(int i=0;i<32;i++)
{
temp = *( (bool*)ptr + i );
if( temp )
cout<<"1 ";
if( !temp)
cout<<"0 ";
if(i==7||i==15||i==23)
cout<<" - ";
}
}
I get some random output
even for nos. like "32" I dont get anything sensible.
why ?
