true

Each variable in an array has the same name and data type

true

In most applications, the values stored in an array come from a file on the computer's disk and are assigned to the array after it is declared

true

The number of elements is always one number more than the array's highest subscript

true

To refer to the first variable in a one-dimensional String array named strFriends, you use strFriends (0) --read "strFriends sub zero"
