Re: [Dev-C++] What's the difference?

[Adam M. <up...@in...>]

Hi.

If you don't need pointers - don't use them. Unfortunately sometimes it is
indispensable to use pointers. One little and simple example:
when you want to pass argument to function and this function
chages its value. To do this you must pass pointer or reference to
the argument. And one more usage of pointers - dynamic memory
allocation.
