Back in the days of K&R, Kernighan and Ritchie published an addendum

C Programming Language".
 The first difference they noted was that
   "Structures may be assigned, passed as arguments to functions, and
    returned by functions."
  From what I can see of the ISO C standards, the current C language
has kept these these features. However, I don't see many C projects
using them.

Weird. Virtually every C project relies on assignment of structures. Passing-returning structs by value might be more rare (although perfectly valid and often appropriate too), but assignment... assignment is used by everyone everywhere without even giving it a second thought.
One dark corner this feature has, is that in C (as opposed to C++) the result of an assignment operator is an rvalue, which can easily lead to some interesting consequences related to structs with arrays inside.
