Answer / kirankumaryakkala
ans. by using unions we can find it see.
union
{
char ch[2];
int i;
}u;
u.i=512;
printf("%d %d",u.ch[0],u.ch[1]);
printf("%d",u.i);
basically u will see this type of implementation while u r
going through some C books.
depending on the storage seen at ch[0],ch[1] u can find.
u can find the output as ch[0]=0,ch[1]=2 \\little endian
(or) ch[0]=2,ch[2]=0\\bigendian
like this u can find the endian....

You have an int array with n elements and a structure with three int members. ie struct No { unsigned int no1; unsigned int no2; unsigned int no3; }; Point1.Lets say 1 byte in the array element is represented like this - 1st 3 bits from LSB is one number, next 2 bits are 2nd no and last 3 bits are 3rd no. Now write a function, struct No* ExtractNos(unsigned int *, int count) which extracts each byte from array and converts LSByte in the order mentioned in point1.and save it the structure no1, no2, no3. in the function struct No* ExtractNos(unsigned int *, int count), first parameter points to the base address of array and second parameter says the no of elements in the array. For example: if your array LSB is Hex F7 then result no1 = 7, no2 = 2, no3 = 7. In the same way convert all the elements from the array and save the result in array of structure.
