As you probably learned in your first programming courses,
pointers to variables allows you to modify variable contents
from a non-local environment. This gives the flexibility of
writing generic functions which do not alter "known" global
variables, but references to "unknown" variables. Such
functions can be reused. Function pointers gives you the
same flexibility, but at a higher level. Instead of calling
a "known" function, one can call any arbitrary "unknown"
function. This is the main advantage of function pointers:
greater flexibility and better code reuse.
