Hi,
Pointers are in a lot of cases faster to use than
variables. As stated in a previous post, type *name
declares a pointer, pointers can only point to the
type declared unless cast to another type. Be careful
with casting though. Their are two other unary
operators for pointers, the & and the *. The & is the
"address of operator". Ex: p=&variable name;
The other operator is *, "at address". Ex: cout << *p
<< endl; This will print what the value of the
variable pointer to is.
Ex: int *p,value=100;
p=&value;
printf("%d",*p) //prints 100
printf(p) //will print the address not 100
This also just scratches the surface though. I like
books by Herb Schildt, he's easy to understand and
detailed.
Hope this helps,
Darryl
