Unix itself does not use arrays. However, some shell scripting languages such as bash or ksh have simple rudimentary uses of a singly dimensioned array.
If you want anything multi-dimensional or special use such as associative arrays, then you need a scripting language such as perl, or awk or python, etc.

Why do you use ampersand symbol for arrays and not for a string?
You don't need to use ampersand for arrays; it's entirely optional even for strings (character arrays). This is because arrays will implicitly convert to a pointer at the slightest provocation. Thus for an array named X, you can either pass the array to a function as X, &X or &X[0], they all refer to the exact same address.
