Answer 4

I need to use them more.

Pointers can be a great asset to C++ programs.

Answer 5

Pointers allow for indirection when manipulating data, in other words a pointer provides an indirect means of accessing the value of a variable. Pointers are very powerful, but are often misunderstood and misapplied. If I sound like I understand pointers, well I might a bit, but not as much as I could or even should. I'm still learning about pointers all of the time.

Read up on pointers and try them out.
