ARRAY
C++ provides a data structure, the array, which stores
a fixed-size sequential collection of elements of the
same type. An array is used to store a collection of
data, but it is often more useful to think of an array
as a collection of variables of the same type.
Instead of declaring individual variables, such
as number0, number1, ..., and number99, you declare
one array variable such as numbers and use numbers[0],
numbers[1], and ..., numbers[99] to represent individual
variables. A specific element in an array is accessed by an index.
All arrays consist of contiguous memory locations.
The lowest address corresponds to the first element
and the highest address to the last element.
