Little endian Vs Big endian

Question

Lets say I have 4Byte integer and I want to cast it to 2Byte short integer. Am I right that in both (little and big endian) short integer will consist of 2 least significant by

Answer 1

First of all, you may already know it but let me mention that the size of int is not guaranteed to be 4 bytes and that of short, 2 bytes across all platforms.

If in your first question you mean something like this:

int i = ...;
short s = (short)i;

then yes, s will contain the lower byte(s) of i.

I think the answer to your second question is also yes; at the byte level the endianness of the system does come into play.
