How do you use pointers to reference the address of an element in an array?

How do you use pointers to reference the address of an element in an array?

We just started going over pointers in my C/C++ class, and I'm a bit
confused at how they work. I am presented with this problem:
Assume you have declared a multi-dimensional array char ma[5][30]. What is
the address of the element "ma[0][0]"? Use two (2) different ways to
assign the address to a pointer variable, p. (Do not give a concrete
address for ma[0][0] - this will vary each time the program is run, based
on the memory allocated.)
I know how much this community frowns on providing the "answers" to a
homework problem. I don't need the answer, but hopefully someone can
explain to me how I can use a pointer to get the address of an element in
an array?
