Hello, I am a learning programmer...I have been practicing on and off for months in java.
I understand what a pointer 'does' and the basic mechanics on how to use them.
But what are their practical uses for a learning programmer like myself?
The only uses I have seen myself are examples of passing pointers through methods instead of the data itself so that you can run your program faster.
I also have seen the example of using pointers to complete a linked list.
Can anyone give me a VERY simple application where pointers are necessary?
