implement it....

Thanks a lot...

Try an analogy. You know what an array of doubles is. How about an array
of structures? That still makes sense. You could have an array in which
each element is a stack. Likewise, you can have a stack in which each
element is a stack. And each element of the "innermost" stack could be an
doubles. Or structures or whatever.

So the crucial thing is to distinguish between elements and combinations of
elements.

At a guess, a stack whose elements are stacks (more
likely pointers to stacks).

Implement a generic stack type. Now stack stacks into it.

For generic stacks you probably want, given that we're in C,
a stack of generic /pointers/. So your generic stack will
use void* pointers to its contained objects. See, I made
it topical.
