Do you need to allocate a structure before you use it if it only holds
one instance and is not in array format?

How could you use it if it isn't declared/defined?

Only if it contains a pointer, or anything that takes up memory. If a
struct just has an int or something in it, you don't have to allocate
any memory.

What do you mean by "allocate". Please give an example.

Context is important; please read <http://cfaj.freeshell.org/google/>.

Of course you have to allocate memory for it. You can do so either by
calling an allocation function such as malloc(), or by declaring an
object (which implicitly allocates memory).

We must do something. This is something. Therefore, we must do this.
