To add to the oddities:

You can copy entire structures by value by doing "x = y".

This ends up being implemented as a memory copy loop, but I'm not sure what happens with the padding bytes. There's a chance they get copied as well, but I really don't know.

In the code base I work with, it's common to see arrays inside of a structure which they're the only member of. This makes it a little easier to copy them, though I'm not sure if that was the intended purpose.

Something like this would be defined in a header...

typedef struct { char myArray[50]; } Test_Struct_T;
