Question about pointer

[Dominic D'Apice]

Hello all,

I'm just discover the pointer concept, i understand how it works.

But, right now, i don't know what is the advantage of utilisation of
pointer in a program

Can someone tell me what king of program we do with pointer ?

Thanks in advance

  There are more than a few ways pointers are useful.  Just two are:
Dynamically allocating memory for objects of varying size and lifetime.
Linking related objects so that a procedure given one can access the other.

You really need a good book on programming (and probably more than one)
to see some of the uses, and problems, of pointers.
