Is this right about pointers

So i just wanted to know if i'm along the right track about pointers so here i go.

Instead of using a variable for holding a value you can use pointers to get the value of a variable in memory. Doing this would help later on with storing information in the memory and accessing it just by getting the address using the '*' and getting the value using the '&'.

This is how i see pointers am i right or am i a bit way of are they just basically better and more reliable way of finding and storing values in memory ?

This site explains it a lot better than I could: http://boredzo.org/pointers/ Also, there's an entire book specifically for C pointers published by O'Reilly Publishing
