Hai friends,
Can anyone write a program in C that would say
whether the given processor is Big endian or Little endian.

Big endian or little endian
Hi all,
I am not so sure but you can use Unions for that..
With the help of unions
decalre the struct of union like
union a
{
int b,
char c,
char d
};
now assign the same address of c and d to b..
what this will do the value of b would now be assigned
to c and d (b higher 8 bits to c or d depending on big
endian or little endian)..
now print the address of c and d corresponding to the
values c and d..
Regards,
Ashwin Mittal.

One solution would be (But you should worry about this aspect unless you really want to know).
main()
{
int x=1;
if((*(char*)&x)==1)
{//Little Endian;}
else
{//Big Endian;}

Did you execute point 1 ?? Prefer to follow point 4 on mailing lists at
least.
For you and people who are as lazy as you.

pushes the original question to the bottom. While any body would prefer
to have the main question at the top, and subsequent replies added to

Embeding inside a message can be better for long replies, while a top

Hi all,
In a big-endian system, the most significant value in
the sequence is stored at the lowest storage address
(i.e., first). In a little-endian system, the least
significant value in the sequence is stored first.
Regards,
Ashwin

Guys!,
See this code
main()
{
int x=1;
if((*(char *)&x)==1)//Little Endian
else //Big endian
}
This is much, much easier to understand.

This means that x is typecasted into char and we are
doing the AND operation with 1 i.e
IF BIG ENDIAN M/C is there then the MSB is placed onto
the leftmost part of memory address.. and when it is
typecated to char (that value 1 is lost) and you will
be having zero as a result of and operation..
like
1stly
(in case of 16bit compilers and BIG ENDIAN M/c)
RIGHT 00000001 MEMADDRESS+0
LEFT 00000000 MEMADDRESS+1
After typecasting into char
the x has value
00000000
And when and opertaion is done...
then
00000000 is the result...
Similary
For the Little ENDIAN , 16 bit compilers
X memory representation
LEFT 00000000
RIGHT 00000001
And after typecasting into char
the value of X
00000001
And when AND operation is done..
the value of X is
00000001
This is how you would be getting the result.....

Ashwin Mittal.

Big endian or little endian
main
{
int x=1;
if ((char)x==1)
printf("little endian");
else
printf("bigl endian");
}
isn`t it more appropriate

Don`t bother to google?
From the words "End In". Refer to the way data are stored in memory -
whether it is "big end in" first or "little end in" first.
Memory goes from low order to high order.
"Big end in" means most significant bytes are stored first (in lowest
memory).
"Small end in" means lest significant bytes are stored first (in lowest
memory).
There is also "middle-endian", in which bytes within 16-bit word are ordered
differently from 16-bit words within 32-bit word.
