A question about a subject in the "C Unleashed" book

Thanks Peter.

In page 37 the book says"

stuct like

stuc FOO foo
memset(&foo,0, sizeof foo);

is not guranteed to have the desired effect if the structure
definition of FOO contains floating point numbers or pointers.
The book recommands usigng {0} to do the job. (struct FOO foo={0})

My question is that we can initialize a stucture in the beginning
of the program using {0} but what about ,for example, middle of a
program?

static struct Foo foo_zero = { 0 };
struct Foo foo;
..
foo = foo_zero;
