"imperative" and "procedural" are the same thing, and C is a prime
example.  It is such because the structure of a C program is a
collection of procedures which start with "main".  Each procedure is a
linear list of statements to be executed in order.

Lisp is "functional".  The functional paradigm is based entirely on
functions.  A function receives some input values (arguments) and
returns some value.  It is based heavily on discrete mathmatics and

The other two categories of programming languages are OO
(object-oriented) and Logic.  Python, C++ and Java are OO languages.
Prolog is a logic based language.
