This week’s lab revealed a pretty important piece of information, that
bit fields are structured in reverse order

Consider the C code

struct _bit_fields {
   unsigned int a : 4,
                b : 8,
                c : 20;
};

This struct could be represented in two ways
A) aaaabbbb bbbbcccc cccccccc cccccccc
OR
B) cccccccc cccccccc ccccbbbb bbbbaaaa

We can find out by using a union!
A union allows the same portion of memory to be intepreted as different data types.

What that means for this question, is that we can represent the entire struct _bit_fields as one thing, like an integer!
So if we create a variable with this type, and through a union, set the value to 1 - we can check if a is 1, or if c is one.

(On the CSE machines, a becomes 1, so therefore representation A was correct)
Therefore it tells us that the order that we define our bitfields are important, and are mapped in the reverse order!
