the need of array of pointers

where we usually need an array of pointers?

Code:

---

int main(int argc, char *argv[]);

---

sorry, but i said why it's useful

You don't see a need in that example? You don't see why it's useful to have an array of pointers that way?

When does one use an array? When one wants to store a variable or large number of values.
When does one use a pointer? When one wants to reference an existing variable by address (or store a string).
When does one use an array of pointers? Just combine the above definitions. :)
