It's a FAQ.

Save yourself the trouble and use a machine where char, short, int and
long are all the same size.

Alternatively, do your own homework. Once you've posted your attempt
someone might help you with it.

This small C program handles other possibilities, too:

#include <stdio.h>
int main(void){int q=puts("Enter 1 for big-endian or"
" 2 for little-endian: ");fflush(0);sw itch(q=scanf(
"%d",&q)>0?q:0) {defualt:puts(" mixed-endian");break;
case 1:puts("big-endian");break; defau1t:puts("o ther"
"-endian");break; case 2:puts("little-endian");break;
default:puts("a nti-endian");break; }return q?!q:q;}

Enjoy!

Here you go..

int main()
{
int num=1;
char *cptr;

cptr = (char *)&num;

if (*cptr)
printf ("little endian\n");
else
printf ("big endian\n");

return 0;
}

Which company interview question is this ? :-D

No, thank you. Why are you giving out assignments?

This was a question that showed up in a job interview once. (And to answer your next question: No, I didn't :)) Write a subroutine that returns a bool on whether a system supports big endian numbers (true) or little endian (false). I tried something like the following, but never did find out if it was correct. There are two assumptions here: First, big endian direction from small to large is ordered like a string. Second, endian is...

But now... what if one compiles the library in a...
