Little endian and Big endian in C programming

JIGAR PATEL Category

This is the most complex concept…. i have read enough on net and some books but still i was not getting this concept. i was not understanding how this will effect my c code. But i have did some experiments with some example code and tried to understand things. and here now i am going to share those examples.

In computing, the term endian or endianness refers to the ordering of individually addressable sub-components within the representation of a larger data item as stored in external memory (or, sometimes, as sent on a serial connection)

You can understand basic things about at

Little endian and Big endian

Big-endian

The most significant byte (MSB) value, which is 0A_h in our example, is stored at the memory location with the lowest address, the next byte value in significance, 0B_h, is stored at the following memory location and so on. This is akin to Left-to-Right reading in hexadecimal order.

Little-endian

The least significant byte (LSB) value, 0D_h, is at the lowest address. The other bytes follow in increasing order of significance.

Now lets see with some code
