x86 is little endian, while sparc is big endian. So question really is asking to find if underlying system is little endian or big endian.

union{
	short s;
	char b[2];
	}x;
	x.s = 1; /* 0(MSB)1(LSB) */
	if( b[0] == 1 ) /* lower address has LSB */
		return x86
	else
		return sparc

public void main(){

}

static int lengthx()

bool endianness()
{
int num;
char *ptr;
num=1;
ptr=(char*) #
return (*ptr); //returns the byte at lower address
}

/*returns true if the machine is little endian,i,e X86 or false if the machine is big endian,i,e sparc */
