What’s the point of using pointers?
There are many instances where pointers will
come in handy. One benefit of pointers
is saving space. If for example you had
a class that contained 10 doubles and an array of 100 strings that will take up
quite of bit of memory. If you need to
reference it without pointers you would actually have to make a new copy of
that whole thing and keep two of them in memory. If you use a pointer instead you are using
about 0.5% of the memory that you would have used otherwise.
As in the example above, you save space by using
*terry to point to the char 'h'. This may not seem like a problem with windows
that has 100’s of MB of memory but if one day you are creating a program for an
embedded system like the ones found in PDA’s or missiles you will only have a
couple of KB of memory to work with.
